Think Beyond Future !

Cryptocurrencies such as Bitcoin and Ethereum are evolving increasingly famous due to their many advancements over traditional fiat currencies. If you want to use any of these blockchain-related cryptocurrencies, you’ll direct to comprehend how blockchain wallets work.

This blog describes what is blockchain wallet, gives justifications as to why you might use a blockchain wallet, and explains the different kinds of blockchain wallets. It also includes blockchain wallets.

Why Use a Blockchain Wallet?

Traditional banking methods pose several issues for doing any transaction. For one thing, transactions are often lagging. For another, any transaction has to die through an intermediate, like a bank, meaning there is a major point of loss. And there are problems in maintaining track of all accounts and credits, data can get threatened, abused, or even deteriorated across numerous systems where the accounts and balances are maintained. Blockchain wallets reduce or delete these issues.

What is a Blockchain Wallet?

A blockchain wallet is a cryptocurrency wallet that permits users to handle different types of cryptocurrencies—for instance, Bitcoin or Ethereum. A blockchain wallet helps someone deal with funds efficiently. Transactions are unassailable, as they are signed. The wallet is available from web devices, including mobile ones, and the privacy and individuality of the user are supported. So a blockchain wallet delivers all the qualities that are required for safe and secure transfers and interactions of funds between different parties.

It is very comparable to the method of sending or accepting money through PayPal or any other gateway used today, but you use cryptocurrency rather. Examples of blockchain wallets have Electrum, Jaxx, Mycelium, and Bitcoin paper wallet. There are many more established on the requirements you have and the security you demand.

How Do Blockchain Wallets Work?

First, let’s examine what private and public keys are and how these legends are related to a blockchain wallet. Whenever you construct a blockchain wallet, you are supplied with a private key and a public key that is associated with your wallet. Let’s use email as an example. If you like to receive an email from someone, you give him or her your email address.

But giving out your email address doesn’t mean a person will be capable to send out emails via your account. Someone would have to understand your email account’s password to do that. Blockchain wallets pursue a matching process using a public key and a private key together. A public key is equal to your email address, you can present it to anyone. When your wallet is developed, a public key is developed, and you can share the public key with anyone in order to receive funds.

The private key is top secret. It’s equal to your password, it should not get felled and you should not tell it to anyone. You use this private key to expend your funds. If someone gets entry to your private key, there is a high chance that your account is compromised, and you might end up losing all the cryptocurrency deposits in your account.

Blockchain Wallet Features

Now that you understand how Blockchain wallets function, it is crucial that you should know about their characteristics. Here are some of the essential elements of Blockchain wallets:

  • Satisfied to use. It’s just like any other software or wallet that you utilize for your day-to-day transactions.
  • Highly secured. It is just a case of booking your private key.
  • Allows instant trades across geographies. And these are barrier-free, without mediators.
  • Low trade fees. The cost of transferring funds is much more inferior than with traditional banks.
  • Allows transactions across numerous cryptocurrencies. This allows you to do easy currency conversions.

Blockchain Wallet Types

There are two kinds of blockchain wallets established on private keys, hot wallets and cold wallets. Hot wallets are like regular wallets that we hold for everyday transactions, and these wallets are user-friendly. Cold wallets are identical to a vault, they store cryptocurrencies with a high level of security.

Hot Wallets and Cold Wallets

Hot wallets are online wallets through which cryptocurrencies can be transferred fast. They are open online. Examples are Coinbase and Cold wallets are digital offline wallets where the dealings are signed offline and then announced online. They are not held in the cloud on the internet, they are kept offline to have high safety.

With hot wallets, private keys are kept in the cloud for more rapid transfer. With cold wallets, keys are in various hardware that is not related to the internet or they are kept on a paper document. Hot wallets are comfortable to access online 24/7 and can be accessed via a desktop or mobile device, but there is the chance of unrecoverable theft if felled. With cold wallets, the process of the transaction benefits in guarding the wallet against unauthorized entry.

Wallets are three kinds:

  • Software wallets.
  • Hardware wallets, which you pack into your USB drive.
  • Usual paper-based wallets, for which you publish your public key and private key on a piece of paper and keep it in a safe place.

Software Wallets

A software wallet that is downloaded on a machine, it could be a desktop or a mobile device, or it could be a web-based wallet that can be accessed online. Breadwallet, Jaxx, and Copay are widespread software wallets. We can further classify software wallets as desktop wallets, online wallets, and mobile wallets.

Desktop Wallets

Desktop wallets are cold wallets in which the private keys are held in cold servers. You can open the wallet from the Internet, do some offline commerce, and then bring it back online. In case the central server is lost, then a cold server, essentially your desktop, is operated as a backup server.

These wallets can be installed on any system but can be accessed only from the system they are established on, so you make certain the desktop or the device on which you are downloading the desktop wallet is secure, and that you’re supporting the hardware and not allowing the machine go anywhere.

These wallets are undoubtedly cost-efficient. Electrum is a popular desktop wallet.

Online Wallets

These are other types of hot wallets that operate on the Internet. Users have the advantage of accessing these wallets across any machine. It could be on any device, or you can need it from your mobile browser. The private keys are held online and are controlled by a third party. For example, GreenAddress is a Bitcoin wallet that is known on the web, has an Android app, is available on a desktop, and also is available on iOS.

Mobile Wallets

Mobile wallets are comparable to online wallets save that they are made only for mobile phone use and accessibility. These wallets have a user-friendly interface that allows you to do transactions efficiently. Mycelium is a mobile wallet.

Hardware Wallets

A hardware wallet is a type of cold storage machine, generally like a USB, that supplies the user’s private key in a covered hardware device. These wallets are identical to portable devices that can be attached to the computer. As noted before, they are less prone to negative attacks and are hack-proof. Ledger, Trezor, and KeepKey are the top hardware wallets on the market.

To make marketing from your hardware wallet, you have to confirm that the hardware wallet is plugged into your computer system.

Paper Wallets

A paper wallet is an offline method for storing cryptocurrencies. The wallet contained both your private key and public key, which are accessed using a QR code. Since these wallets are safe, they are widely used for holding large amounts of cryptocurrencies. Bitcoin Paper Wallet and MyEtherWallet have used paper wallets.

A paper wallet functions with your software wallet to move funds from your software wallet to the general address displayed on your paper wallet. First, you park your funds in a software wallet, then you share the funds from your software wallet to the public address printed on the paper wallet.

Blockchain Wallets Comparison is a wallet that supports both Bitcoin and Ethereum. It is comfortable to operate and has a low transaction fee. It has an API that is revealed, so you can easily make your own custom wallets.

Ledger Nano S is a hardware wallet that delivers high protection for your account. It is known for Bitcoin, Ethereum, and Litecoin. It is also likely to maintain numerous accounts and access them anytime.

A Bitcoin paper wallet allows you to print your own tamper-resistant Bitcoin wallet. It minimizes the threat of hacking.

Jaxx allows a user to trade currencies within the wallet. It is known for Bitcoin, Ethereum, Litecoin, and many other cryptocurrencies. With Jaxx, a user can view his or her balance as soon as the processing is finished.

Use Case: Cryptocurrency

- Posted in App Development by

Crypto acquisitions have come a long way since Bitcoin. What began out as a P2P payment system has generated an array of use cases that stretch far beyond the initial identification of cryptocurrency. While the prior function of crypto assets such as ETH and BTC is a subject of some discussion, what’s undeniable is that digital currencies can now be utilized for more than merely paying for interests and favours. Here are the five most important use cases for crypto investments that establish the extent of the fintech revolution taking place.

Use Case 1: Digital Cash

Created as a peer-to-peer electronic money system, if the identification of Satoshi’s whitepaper is to be accepted at face worth, Bitcoin lived up to its billing for preferably five years. Before the mainstream arrived terms with Bitcoin, it fueled a nascent digital economy that included black market goods and gambling. It was also obtained by tech-savvy vendors and early adopters, for shopping everything from graphics cards to t-shirts.

As web fees started to rise, causing multiple merchants to drop support for BTC, growing followers of Bitcoin Core loyalists, who would come to be known as maximalists, started supporting a store of value description over that of a medium of exchange. With BTC becoming problematic for low-cost payments, the P2P torch handed to Bitcoin Cash, which started to live in mid-2017 as a fork of Bitcoin. The BCH network has since held its community’s purpose of enabling fast and low-cost payments, with thousands of merchants accepting bitcoin cash in-store and online.

Meanwhile, during the 2017 ICO boom, scores of crypto projects started up with generic cost tokens attached to them as the reason for increasing funds. When the tide ran out on the crypto demand in early 2018, it became evident that aboriginal ERC20 payment tokens absolutely weren’t feasible, with most passing a slow death due to high velocity and low liquidity. The crypto assets that endure today as P2P currencies are mostly restricted to pre-2015 coins such as dash and litecoin.

Use Case 2: Programmable Money

Smart contracts even predate Bitcoin, having been created by Nick Szabo. Smart agreements are simply the blockchain-based executable principles that actions a certain outcome supplied certain requirements have been met. Although interchangeable with Ethereum, most crypto grids have a degree of smart contract programming, including Bitcoin itself.

RSK has planned a smart contracting forum that capitalizes on the safety of the Bitcoin blockchain and its web effects. As BTC’s power over altcoins has increased this year, so has the allure of making Bitcoin ahead of less decentralized options such as Tron and EOS. As a result, developers that might have formerly flocked to so-called “second-gen” blockchains, have had cause to examine Bitcoin in a whole fresh light. As for the Bitcoin Cash network, Simple Ledger Protocol has enabled the distribution of sub-tokens, constructed using opcodes that Satoshi initially integrated into the Bitcoin protocol.

Use Case 3: Collateral

Lending has evolved into one of the most critical applications of the burgeoning decentralized finance movement, allowing individuals to collateralize fiat loans against cryptocurrency and vice-versa. On Ethereum, lending usefulness such as Maker, Compound, and Instadapp have flourished, with hundreds of millions of dollars worth of support now locked up in lending protocols. Other defi lending answers retain Dharma and Dydx, while centralized options include Salt, Youhodler, and Nexo, which allow people to get a fiat loan in interaction for locking up their crypto. There’s also the option for holders to make annualized curiosity by locking their cryptocurrency into these lending protocols.

Use Case 4: Governance

Governance might not sound like the most effective of use cases for cryptocurrency, but an on-chain poll is a very good means of ensuring provable voter turnout. Bitcoin miners have long engaged themselves in elementary governance by signalling help for protocol transformations by signing new blocks.

Blockchain government has gotten more refined since then, with Dash, introducing a thriving budget voting means that’s been imitated by scores of projects. There are now crypto assets whose primary function includes governance, such as 0x, maker, condemned and definitely. In acquisition, crypto projects such as Aragon in corporate governance by enabling token-holders to vote on key findings using a damp. So far, participation in on-chain administration has been downward for crypto projects, showing that voter apathy is a universal problem.

Use Case 5: Collectibles

non-fungible tokens mean unique digital assets. These generally comprise in-game collectibles such as skins or characters, or in virtual fact games can represent digital land or possessions. This causes it feasible to trade the assets to fellow collectors or parties and provides full ownership of the collectible. That’s not to say that NFTs are completely decentralized, however, as their value still relies on a central authority, say Cryptokitties or Cheeze Wizards, which hosts the picture associated with each token and contains the virtual world it works in. Nevertheless, collectibles represent an improving vertical within the cryptosphere, with NFTs possible to become extremely embedded into esports and virtual reality in the years to come.

Evolving Applications for Crypto Assets

Cryptocurrencies are immature, and thus multiple of the envisioned use cases for them have yet to totally materialize, often because the infrastructure is always being created. Security tokens, hybrid tokens, products, crypto commodities, privacy coins, stablecoins, work tokens, discount tokens and many more have yet to prove themselves but are possible to achieve a foothold as crypto adoption grows and the ecosystem matures.

From national reserve currency to time-stamping documents, Bitcoin resumes proving its versatility. One of the best things about permissionless grids is that anyone can operate them however they stay fit, be it at the bottom layer or via secondary and tertiary layers. The crypto space has grown in bounds and bounds over the past decade. 10 years from now, crypto assets will be serving programs that we have yet to envisage, let alone design.

Make sure your future app development company uses the most well-appropriate app development framework in the case of both born and hybrid apps. They must also be explicit about the fact that the code belongs to the customer since they are spending for its development.

To ensure proprietary privileges of the mobile app and its coding, ask the vendor to sign a copyright agreement expressing that you hold the mobile app entirely, including, design, source code, and all of the contents.

Customer References and Past Work

Before you hire a mobile app vendor, make sure that you look at their past work. Ask them to guide you to some previous project case analyses, and live apps, in order to assess the rate of their work. Most mobile app development firms will have an online portfolio, or a paper listing their past work.

Check the apps they have developed so far, and download some of them to check their functionality, assessments, and ratings. Always go for a professional mobile app developer, and examine a few significant things such as a checklist of appropriate skills that you are examining for your spouse. In addition, check on their earlier clientele, as their feedback could be very beneficial.

Once the development process is fulfilled, the app must be tried to guarantee product quality. App testing is an enormously significant step before any app can be established for the public. Here are a few questions you require to ask your vendor:

  • Are they only answerable for the development approach of the app, or will they also test the app?
  • How will they carry out their beta testing, in order to resolve problems?
  • How quick are they in resolving issues?

In addition, you must make sure that the vendor has a reliable team of rate analysts who utilize the latest tools while performing the test.

Data Security

Security concerns such as personal violation, system info leaks, uncertain storage, and insecure deployment, can negatively impact your app’s lifespan. Therefore, choosing vendors that make mobile apps with secure code is a critical step in the app development process.

Third-Party Software Integration

The best mobile application development companies can equip you with a broad scope of elements and services to be incorporated into your app.

It is important for an app today, to present a whole experience, rejecting no need for the user to proceed to the website interface for conducting an extra action like payment or customer care-related actions. Apps ought to satisfy these expectations.

This is why businesses must confirm that the future mobile app vendor equips the best back-end system integration procedures to underestimate the cost of mobile answers. Look for integrated mobile apps with back-end applications such as CRM, POS, and ERP, to get adequate results and better-quality products.


Before hiring a mobile app development company, verify how they offer an app to the app store, and how they manage the mobile app liberation for a customer. A qualified vendor will either present the app for you or direct you through the recommendation process.

Always look for a company that will collaborate with you throughout the app development procedure, and is prepared to ship the code once the initial development is finished, and the app is hosted.

All the courses inside an application are not made by the app owners therefore they have the educational institutional courses completed by top educators. When a student inquiry for courses on a particular subject, the courses of these institutions seem right at the top of the search bar. This occurs because the colleges and institutions pay an extra amount to these e-learning apps to construct their courses occur at the top of the courses list.

Challenges in e-learning Mobile App development

Developing study material and documents to access

Creating the best study content be a great challenge for app developers. The success of an e-learning mobile application depends very much on the study material. Apart from the online live classes, learners want notes and documents for revision. Generating this material is paramount if you need your students to stay on the application and continue with what you are providing.

Video content development

Creating an online video takes a lot of effort behind the scenes. The same is the case with e-learning videos. Making a video with an educator teaching an exact subject is not the final or first step, there are other directions associated with it like editing the shooted video to make it worth watching without any useless content, mixing other major things such as sound, proper light effects, framework and more.

Tutor training programs development

The teachers who are opted to teach the students on the e-learning platform require to be taught the insights that are needed for taking a class online. The programs for teachers require to have stuff on multiple subjects from which the teacher can learn and broaden his overall understandings of a particular subject. Addition of multiple courses such as video courses, online teaching programs that facilitate classes through video conferencing, text chat messages, etc.

Server load balance for hassle-free streaming

Load balancing is the efficient distribution of network for application traffic across various servers in a server farm. There require a load balancer among the user devices and backend servers which will get and then give requests to any server that is able of completing them. This process is important as the live classes require to be shot before any interference otherwise the complete flow of studies will be interrupted.

Discussion board

This program in the app makes increasing the interaction among the app customers. With the help of discussion forums, the app customers can simply produce a new topic or include a comment under the topic.


Making the competition among the learners is a large way of motivating them and leaderboards are integrated into the application to do just that.

Chat room+Video steaming

This option makes the students ask their teacher a doubt about a topic through a text in the chat room even in the middle of the class. The mentor can stop proceeding further to pay attention to the doubt of the learner and only moves on after providing the student with the solution for his problem.

Video lesson streaming

E-learning applications are initially in attention as they give free video lessons for the learners. Through the e-learning apps, the students can stream a live video lesson to gain perfect knowledge on the topic they are looking to master.

Case Study: Food Delivery App

- Posted in App Development by


Foodiday is a food delivery application that provides food delivery at your doorstep in very little time and with the best packaging and hygiene. By providing the food from every famous food place nearby online food ordering is the process of ordering food from an application. The product can be either ready-to-eat food. This online food ordering system sets up a food menu online and customers can easily track the orders. There are various facilities provided so that the users of the system will get service effectively. Increasing the use of smartphones is also considered as a motivation. So that any users of this system get all services with a single click. Another motivation can be considered as the system will be designed to avoid users making fatal errors, users can track their food items through GPS users can provide feedback and recommendations and can give ratings, It will give appropriate feedback to restaurants. In the proposed system there will be no limitation on the number of orders the customer wants.


With the development of Foodiday.We know that people look over the mobile app for ordering food to comfort their life. With the huge number of young professionals in the big cities, people can’t find much time to prepare food. By developing this food delivery app to make the job too easy in Kerala. Download this app from the play or app store, register into the app, select the menu to place food delivered to your doorstep. Most of the young professionals and other office goers found this method too easy to place a food delivery app in Kerala and has become in stand popular among users. People have a huge number of choices to select among the apps to compare and pay with offer price from online food ordering apps.

Foodiday is a food delivery app designed to make it simple to find and order food one is craving.

The time frame for developing a food delivery app:

  • While using flutter:16 weeks
  • While using Native-Android:16 weeks
  • While using Native-IOS:16 weeks

Below are some of the issues that we wanted the redesign to address.

The community of existing food delivery apps causes it hard to find dishes one wants.

  • Grouping dishes by eatery forces users to scroll through long restaurant menus
  • Many dishes have no pictures making it so effort to scan and know what they are ordering

Current explanations do not sufficiently address those with dietary restrictions

  • There are no options to ban foods with certain ingredients
  • User has to read dish explanations or avoid ordering from certain restaurants

Suggested restaurants and dishes are not personalized

  • No option to count dish or restaurant to favourites
  • Easy to reorder past dishes, but falls short of suggesting similar ones

The interface offers too many food options

  • Many customers who use the service are usually hungry, busy, or tired and needs instant-gratification
  • Do not require making too many decisions
  • Lower patience levels
  • Want things very quick

My Role

  • Do competitive study by trying contender apps and reading app reviews
  • Make user interviews with students and instructors who order food online or eat out
  • Develop and post user surveys online
  • Participate in generating user personas


Domain Research

With the project idea expressed, the team identified the iOS App Store for food delivery apps. This gave us a better sense of the current food delivery apps out there. For each app, we determined what key elements they had and read reviews to determine pain points and what features people like. We used this data to formulate our user interview questions and will review them when making workflow and design decisions.

Below are some concepts collected from user reviews:

  • Need choice to cancel the order
  • Need right notification of delivery will be late
  • Notification if the dish is unavailable and suggests another
  • Advise customer if ordering near restaurant closing time
  • Option to include a dish to favourites for easy reordering
  • See order status and delivery ETA on the home screen
  • display contact info of deliverer and restaurant
  • display order number with client support phone number

User Interviews

My team reached around interviewing students and instructors to know about the following:

  • How often, why, when, and how they order food online
  • Why they would select one food delivery service over another
  • Their background using one of the food delivery services
  • How food allergies affect their placement experience
  • How they locate new restaurants and dishes
  • How they order food in the app
  • Areas they consider competitors can enhance on

As I had never ordered food online before, conducting user interviews gave me a better sense of what users run through in the ordering and delivery knowledge by responding to the 5 W’s (who, what, where, when, why, and how). It was also useful in coming up with more questions as unexpected points were introduced.

From the user interviews, we found that customers are:

  • Food-based or restaurant-based
  • Price susceptible and are concerned about delivery fees
  • Enjoying more correct order status information
  • Visually driven.
  • Neutral in helping local businesses and organics

User Surveys

Afterwards, we developed and deployed a user survey on different communities on Reddit which garnered 315 answers over 3 days. The survey was one of the key ways of deciding what elements are required and not with more significant confidence. It also ensures some of the user interview results.

The survey results also modified the initial project idea, which was a “Don’t make me think” technique to food ordering with customized proposals, rating, scheduling, and budgeting.

We discarded the scheduling and budgeting features as most people are not curious about scheduled deliveries and people order food a lot further from the app, making budgeting unusable.


With the research piece concluded, we drove onto the planning stage where we developed user personas, customer journey maps and user flow diagrams.

User Personas

From the user interview conclusions, we made 2 user personas, restaurant-based and food-based users. Restaurant-based users track the current model of food delivery apps where dishes are grouped by the restaurant. Food-based users follow a new model where they are more curious about finding dishes rather than restaurants.


  • Need to visit the eatery first before ordering online
  • Need to read restaurant reviews and blog mentions
  • Usually, order from the usual restaurants
  • Will utilize whatever food delivery app the restaurant endorses


  • Enquire for food to satisfy one’s cravings.
  • Look at pictures to comprehend what to expect
  • Periodically tries ordering from new restaurants


  • Don’t need to or couldn’t cook or pick up food
  • Deals price, restaurant type, delivery fees, and speed are the most
  • Looks at a distance, thoughts, pictures, and values when selecting a restaurant

Customer Journey Map

Afterwards, we made a current and prospective customer journey map to emphasize the touchpoints, actions, thoughts, and pain points. To help us know the current flow, we downloaded the foodiday mobile app and executed through methods to see how the apps completed or did not meet the user’s requirements.

User stories

Here are the user narratives showing the user’s plans for each major page.

Dishes page

  • As a restaurant-based user, I need to identify restaurants so I can call from my favourite restaurants
  • As a restaurant-based user, I enjoy discovering the best restaurants for a typical cuisine in my area so I can order delicious food
  • As a food-based user, I like to search for distinct dishes so I can see food I am craving for
  • As a user, I like to see presented dishes founded on my choices so I do not have to create as many decisions
  • As a user, I like to discover dishes with free delivery or other values so I can save money
  • As a user, I like to see my famous dishes so I can reorder them

Filter page

  • As a user, I like to sort dishes by distance, rating, cost, and favour so I can uncover dishes fast
  • As a user, I like to filter dishes by cuisine or allergies so the recommendations fit my tastes and dietary limitations

Dish info page

  • As a food-based user, I like to see pictures of words so I have an idea of what I am calling
  • As a user, I like to know which restaurant a dish comes from so I can create reported purchasing decisions
  • As a user, I like to check restaurant reviews before summoning so I can be guaranteed the food quality
  • As a user, I like to know the restaurant beginning hours so I understand when they can deliver
  • As a user, I like to count dishes to my favorites so I can readily revisit and/or reorder them
  • As a user, I like to be capable to convey a link to the dish to others so I can bring others to check it out
  • As a user, I want to customize dish toppings so the dish fits my tastes
  • As a user, I like to count a note to a dish so I can select element changes or omissions

Cart/Checkout page

  • As a user, I like to understand the estimated total before fitting out so I know how much I will be paying before I input the lesson and payment facts
  • As a user, I like to be able to go back to scanning so I can count more dishes to the cart
  • As a user, I like to change the dish options or remove dishes in case I switch my mind
  • As a user, I like to have my address and payment points saved so I can fit out faster
  • As a user, I like to be capable to count delivery instructions so the delivery agent can buzz themselves in
  • As a user, I want to have the opportunity to have the pass emailed to me so I can get job reimbursements

Order status page

  • As a user, I like to have the accurate GPS tracking of my order so I understand when it will arrive
  • As a user, I like to be able to call the client consent or the delivery agent so I can track up if something goes wrong
  • As a user, I like to be capable to cancel an order if I made a misstep
  • As a user, I like to order the food and delivery service individually so my rating is more precise
  • As a user, I like to pay the delivery tip after the delivery so I can tip according to the delivery rate
  • As a user, I like to see tickets of past orders so I have a record if the order that reaches is incorrect


For this project, the group determined to try a hybrid approach to prototyping where rather than making the mockups from scratch for each set of fidelity, we repeated them. This will permit more time for testing and fixing the prototype. Extra time was also given to understanding how to build a high-fidelity prototype with spirits in Invision Studio.

What is bootstrap?

Bootstrap is an available and open-source CSS framework aimed at responsive, mobile-first front-end web development. It includes CSS- and javaScript-established design templates for typography, forms, buttons, navigation, and other components.

What is the bootstrap grid?

The Bootstrap Grid System is used for layout, especially Responsive Layouts. Recognition of how it operates is vital to understanding Bootstrap. The Grid is made up of groupings of Rows & Columns inside 1 or more containers. The Bootstrap Grid can be used only, without the Bootstrap JavaScript and other CSS Elements. You are just required to download and reference the “bootstrap-grid.css” which includes the Grid and Flexbox classes. More info on only doing the Bootstrap Grid CSS.

Here’s the most general example of using the Grid:

< div class="container">
  < div class="row">
     < div class="col">I'm your content in the grid! < /div>
  < /div>
< /div>

What are the different types of bootstrap grid systems?

Bootstrap grid is a great system for creating mobile-first layouts. It's a very extensive tool with a large number of benefits. Below we give you the core principles. It's an uncomplicated overview of the most generally used examples. Bootstrap’s grid system uses a set of containers, rows, and columns to design and align content. It’s built with a flexbox and is fully active.

What are the basic examples of a bootstrap grid system?

Below is an illustration and an in-depth explanation of how the grid system comes together.

< div class="container"> 
< div class="row">
 < div class="col-md"> One of three columns < /div> 
< div class="col-md"> One of three columns < /div> 
< div class="col-md"> One of three columns < /div> < /div> < /div>

The above example produces three equal-width columns across all devices and viewports using our predefined grid classes. Those columns are centered in the page with the parent .container.

Taking it to step by step:


Bootstrap needs a containing component to wrap site contents and house our grid system. Without a container, the grid won't operate properly.


Rows build parallel groups of columns. Therefore, if you need to break your layout horizontally, use row.


Bootstrap's grid system allows up to 12 columns across the page.

How does it work?

Breaking it down, here’s how the grid system comes together:

  • Our grid supports six responsive breakpoints. Breakpoints are based on min-width media questions, meaning they assume that breakpoint and all those preceding it. This means you can constrain container and column sizing and behaviour by each breakpoint.
  • Containers horizontally pad your content. Use .container for a responsive pixel width, .container-fluid for width: 100% across all viewports and devices, or a responsive container for the mixture of fluid and pixel widths.
  • Rows are covers for columns. Each column has horizontal padding for controlling the space between them. This padding is then checked on the rows with negative margins to defend the content in your columns is visually arranged down the left side. Rows also hold transformer classes to consistently apply column sizing and gutter classes to improve the spacing of your content

  • Columns are amazingly flexible. There are 12 template columns free per row, allowing you to perform different sequences of components that traverse any number of columns. Column classes show the number of template columns to span. widths are set in sections so you always have the same corresponding sizing.

  • Gutters are also warm and customizable. Gutter classes are open across all breakpoints, with all the same areas as our margin and padding spacing. Change regular gutters with .gx-* classes, upright gutters with .gy-*, or all gutters with .g-* classes. .g-0 is also available to switch gutters
  • Sass variables, maps, and mixins power the grid. If you don’t need to use the predefined grid properties in Bootstrap, you can do our grid’s origin Sass to build your own with more semiotic markup. We also add some CSS custom properties to consume these Sass components for even larger flexibility for you.

What are the most common examples?

A few of the most popular grid layout examples to get you close with construction within the Bootstrap grid system.

Five grid tiers

There are five Bootstrap grid system, one for each range of devices we support. Each tier creates at a minimum viewport size and default to the greater systems unless overridden.

< div class="row">
  < div class="col-4">.col-4< /div>
  < div class="col-4">.col-4< /div>
  < div class="col-4">.col-4< /div>
< /div>
< div class="row">
  < div class="col-sm-4">.col-sm-4< /div>
  < div class="col-sm-4">.col-sm-4< /div>
  < div class="col-sm-4">.col-sm-4< /div>
< /div>
< div class="row">
  < div class="col-md-4">.col-md-4< /div>
  < div class="col-md-4">.col-md-4< /div>
  < div class="col-md-4">.col-md-4< /div>
< /div>
< div class="row">
  < div class="col-lg-4">.col-lg-4< /div>
  < div class="col-lg-4">.col-lg-4< /div>
  < div class="col-lg-4">.col-lg-4< /div>
< /div>
< div class="row">
  < div class="col-xl-4">.col-xl-4< /div>
  < div class="col-xl-4">.col-xl-4< /div>
  < div class="col-xl-4">.col-xl-4< /div>
< /div>

Three equal columns Get three equal-width columns starting at desktops and scaling to great desktops. On devices, tablets and below, the columns will default stack.

< div class="row">
  < div class="col-md-4">.col-md-4< /div>
  < div class="col-md-4">.col-md-4< /div>
  < div class="col-md-4">.col-md-4< /div>
< /div>

Three unequal columns

Get three columns begins at desktops and scaling to multiple widths. Don’t forget, grid columns should include up to twelve for a single block. More than that, and columns create stacking no matter the viewport.

< div class="row">
  < div class="col-md-3">.col-md-3< /div>
  < div class="col-md-6">.col-md-6< /div>
  < div class="col-md-3">.col-md-3< /div>
< /div>

Two columns

Get two columns creating at desktops and scaling to great desktops.

< div class="row">
  < div class="col-md-8">.col-md-8< /div>
  < div class="col-md-4">.col-md-4< /div>
< /div>

Two columns with two nested columns

nesting are simple—just put a row of columns within an existing column. This provides you two columns scaling to large desktops, with another two within the larger column.

At mobile machines sizes, tablets and down, these columns and nested columns will stack.

< div class="row">
  < div class="col-sm-6 col-lg-8">.col-sm-6 .col-lg-8< /div>
  < div class="col-6 col-lg-4">.col-6 .col-lg-4< /div>
< /div>
< div class="row">
  < div class="col-6 col-sm-4">.col-6 .col-sm-4< /div>
  < div class="col-6 col-sm-4">.col-6 .col-sm-4< /div>
  < div class="col-6 col-sm-4">.col-6 .col-sm-4< /div>
< /div>

Mixed: mobile and desktop

The Bootstrap v5 grid system has five t classes: xs, small, medium, large, and extra-large. You can use almost any mixture of these classes to build more dynamic and suitable layouts.

Each classes scales up, meaning if you plan on setting the equal widths for md, lg and xl, you only require to md.

< div class="row">
  < div class="col-md-8">.col-md-8< /div>
  < div class="col-6 col-md-4">.col-6 .col-md-4< /div>
< /div>
< div class="row">
  < div class="col-6 col-md-4">.col-6 .col-md-4< /div>
  < div class="col-6 col-md-4">.col-6 .col-md-4< /div>
  < div class="col-6 col-md-4">.col-6 .col-md-4< /div>
< /div>
< div class="row">
  < div class="col-6">.col-6< /div>
  < div class="col-6">.col-6< /div>
< /div>


Additional included classes in Bootstrap make containers that are wide until a particular breakpoint.

< div class="container">.container< /div>
< div class="container-sm">.container-sm< /div>
< div class="container-md">.container-md< /div>
< div class="container-lg">.container-lg< /div>
< div class="container-xl">.container-xl< /div>
< div class="container-xxl">.container-xxl< /div>
< div class="container-fluid">.container-fluid< /div>

What is Adobe XD?

Adobe XD is a vector-placed UI and UX design tool and it can be used to design anything from smartwatch applications to full-fledged websites. Let’s take a glance at what it gives designers and why it’s become such a dominant tool in web design management.

What is Adobe XD used for?

What’s essential to retain is that Adobe XD addresses the two main problems Photoshop and other graphics applications couldn’t:

  1. Communication design isn’t static. A designer cannot give a fluid and dynamic design using pixels simply.
  2. A modern design method requires more than a polished completed article. Wireframing, iteration, and performance are all part of the collaborative arrangement with UI and UX design.

Adobe XD is a model for vector-based UI design, wireframing, interactive design, prototyping, and great-fidelity web design, for whole teams.

How can you export Adobe XD assets?

Start your Adobe XD file and choose the asset or the artboard you require to export. To select an artboard, select the artboard title.

You can also identify assets or artboards for exportation and then export them all in size. To mark assets for export, remove the Layers panel and press the Mark for Batch Export icon.

To transport a JPEG on macOS, select File > Export. On Windows, select the Hamburger menu, and select Export. There are 3 options to export:

  • Batch: Export assets that are identified using the Mark for Export option.
  • Selected: Export chosen assets.
  • All Artboards: To transport all the artboards in your design.

When you transport assets as JPEG, you can place the state level of the exported JPEG according to your requirements. Want any of the percentage benefits in the Quality drop-down list, navigate to the destination folder, and click Export.

If you have any doubt about this Adobe XD tutorial and Adobe XD plugins. Don’t hesitate to contact us through the given email. Airo global software will always be your digital partner.

What Is Augmented Reality In Flutter?

- Posted in Flutter by

AR core in flutter is a wonderful plugin that gives us an API to perform Augmented presence in flutter applications. This is one of the emerging new technologies in the business. With this plugin, we shall consider the different features presented by this plugin the flutter, so let’s start.

How to Enable ARCore?

To qualify ARCore functionality in Android Studio you require to complete the following steps:-

  1. Include AR Required or AR Optional entries to the manifestAR


You need to include the below entries in your AndroidManifest.xml file:-

< uses-permission android:name="android.permission.CAMERA"  />
< uses-sdk android:minSdkVersion="24" />
< uses-feature android:name="" />
< application …>
   < meta-data android:name="" android:value="required" />

AR Optional
< uses-permission android:name="android.permission.CAMERA" />
< uses-sdk android:minSdkVersion="14" />
< application>
   < meta-data android:name="" android:value="optional" />
< /application>

The difference between the AR Optional and AR Required is that AR Required app requires an ARCore Supported Devices that had Google Play Services for AR-enabled in it. In AR Required apps the play store automatically stores the Google Play Services for AR.

While in AR Optional apps can be installed and run on the machines that don’t support ARCore and also play store will not enable the Google Play Services for AR automatically.

  1. Modify build.gradle

Please ensure that your project's build.gradle file includes the below code.

allprojects {
   repositories {

Add the below dependencies in your app-level build.gradle file

dependencies {
 implementation ''
  1. Sceneform plugin in your app-level build.gradle file
android {
   compileOptions {
       sourceCompatibility 1.8
       targetCompatibility 1.8
dependencies {
   implementation ''
   implementation ''
  1. Enable android X

Include the below code into your


Which are the Classes provided by the plugin?

There are a total of 13 classes provided by this plugin.

  • ArCoreView
  • ArCoreController
  • ArCoreFaceView
  • ArCoreFaceContrller
  • ArCoreSphere
  • ArCoreCylinder
  • ArCoreCube
  • ArCoreNode
  • ArCoreMaterial
  • ArCoreHitTestResult
  • ArCoreRotatingNode
  • ArCorePlane
  • ArCoreReferenceNode


This class returns the view kinds. There are two kinds of views in it.


There are 4 properties in it:-

  • onArCoreViewCreated
  • enableTapRecoginzer
  • enableUpdateListener
  • type


This kind takes an ArCoreController. We shall discuss ArCoreController in our later section.


Initially, set to false. It is made an augment by MethodChannel.


Initially, set to false. It is used as an augment by the MethodChannel.


It is a view type, it is AUGMENTEDFACE, STANDARDVIEW. It is set to STANDARDVIEW by automatic.


This controller used to add a ArNode using addArCoreNode function, include a ArCoreNode with anchor using a addArCoreNodeWithAncher function and also remove node using removeNode function.


It is a stateful widget that makes an ArCoreAndroidView. It has two characters: enableAugmentedFaces, onArCoreViewCreated.

At first, enableAugmentedFaces is set to false.

Zeplin is a well-designed curriculum that feels lightweight but is really pretty robust. I'd say it's proper to call it the industry standard for delivering off designs to engineering. Here's a quick walkthrough.

What is Zeplin?

Zeplin is a collaboration device for UI designers and front-end developers to help teams with the design hand-off, allowing designers to upload their wireframe designs from Sketch and add them to project folders in Zeplin.

Why should anyone use Zeplin?

One should use Zeplin for the below reasons -

  1. Once you build mockups on the sketch, all you have to do is transport the artboards on Zeplin with the select a single button.
  2. Zeplin provides you to club added artboards into a group and arrange them according to your choice which will be repeated in every other user who is a member of the project.
  3. That being said, various users can run on a project and add comments or bookmark any particular mockup.
  4. It follows version control very effectively and updates mockups accordingly.

How to use Zeplin to automatically generate measures, styles, and assets?

  • Download Zeplin and create an account
    Go over to to build a Zeplin information and connect the Mac app. You get 1 project for free.
  • Start a new project in Zeplin
    Once you've established Zeplin on your Mac, keep your project type.
  • Choose your pixel density
    If you're running with the standard iPhone artboard in Sketch, you're running in 1x.
  • Export your artboard from Sketch to Zeplin
    With the artboard chosen, use the easy-to-remember shortcut to transport the artboard to Zeplin.
  • View your mockup in Zeplin
    In Zeplin you can agree on any element in your plan to get all of its features: position, spacing, color, text styles, etc. They even provide you with a nice "copy" button so you can simply take the exact copy you've written, eliminating any room for error in spelling.
  • Share the specs with your developer
    If you'd like to share a single screen, you can quickly grab a link from the right-hand panel when observing an original screen in Zeplin.

However, I'd suggest going back to the Project Dashboard view in Zeplin, where you can request the developer to the project using their email address.

Those are the basics of Zeplin, and frankly, there's not much difference to it, which is excellent. Try it as a free account and see if it improves your workflow. Zeplin also has a Slack combination that will suggest channels when innovative designs are combined or changed. I've found it to be a bit overkill, but if you're into that sort of thing, then go for it!

There are multiple social login features to use in Android apps. Here we will know about social login using Facebook, so we need to integrate the Facebook SDK in the project to make use of Facebook login.

What are the steps needed to build a Facebook login page?

First thing you need to do is to have a Facebook developer account and then build a new app. Install android studio and open or create a new project where you want to include Facebook login. In your project, include the following code in your Project.

    repositories {

Now, add the following code in Module:app with the new version of Facebook Login SDK in it.

dependencies {
     implementation ''

Sync the project Now start with app -> res -> values -> strings.xml file to include the lines and replace the [APP_ID] with your APP_ID, which you can get from Facebook Developer console. Open app -> manifest -> manifest file and add this line outside of the application. Include the meta-data element inside the app element in AndroidManifest.xml file. Now first thing you need is Key Hash, so include these lines in the activity class before Facebook login code:

protected void onCreate(Bundle savedInstanceState)
    ... printHashKey();

    public void
    // Add code to print out the key hash
    try {
        PackageInfo info
            = getPackageManager().getPackageInfo(
        for (Signature signature : info.signatures) {
            MessageDigest md
                = MessageDigest.getInstance("SHA");
                  Base64.encodeToString(                      md.digest(),
    catch (PackageManager.NameNotFoundException e) {
    catch (NoSuchAlgorithmException e) {

Now run the application. You will see Key Hash value in logcat, save this for later needs. Go to Facebook Developers console and choose setting -> Basic -> Add Platform and a popup will open up to select a platform. Select Android as a platform. Include your project package name under ‘Google Play Package Name’. Add the class name where login will be implemented in projects like ‘LoginActivity’ and also include the key hash value under ‘Key Hashes’. Now in android studio, include this personalised button in your *.xml layout file:

Include this code in app -> res -> styles.xml :

You can personalize this button instead of an above custom button, you can use the Facebook button also as Facebook LoginButton. Make a file named ‘bg_button_facebook.xml’ in app -> res -> drawable folder Now make a button in *.java file and some syntax to initialize Facebook SDK :

// Declare variables
private Button mButtonFacebook;
private CallbackManager callbackManager;
private LoginManager loginManager;
    protected void onCreate(Bundle savedInstanceState)
        = findViewById(;
    callbackManager = CallbackManager.Factory.create();
          mButtonFacebook.setOnClickListener(new View.OnClickListener() {
            public void onClick(View v)

Add ‘facebookLogin’ option outside onCreate() in the java file. This is the program code for Facebook login response.

public void facebookLogin()
        = LoginManager.getInstance();
        = CallbackManager.Factory.create();
            new FacebookCallback() {
                public void onSuccess(LoginResult loginResult)
                    GraphRequest request = GraphRequest.newMeRequest(
                         new GraphRequest.GraphJSONObjectCallback() {
                            public void onCompleted(JSONObject object,
                                                    GraphResponse response)
                                  if (object != null) {
                                    try {
                                        String name = object.getString("name");
                                        String email = object.getString("email");
                                        String fbUserID = object.getString("id");
                                        // do action after Facebook login success
                                        // or call your API
                                    catch (JSONException | NullPointerException e) {
                    Bundle parameters = new Bundle();
                        "id, name, email, gender, birthday");
                public void onCancel()
                    Log.v("LoginScreen", "---onCancel");
                public void onError(FacebookException error)
                    // here write code when get error
                    Log.v("LoginScreen", "----onError: "
                                             + error.getMessage());

Now include another needed option ‘disconnectFromFacebook’ for login , similarly add this to onCreate. This is used to disconnect applications from Facebook as there is no need to stay connected.

public void disconnectFromFacebook()
    if (AccessToken.getCurrentAccessToken() == null) {
        return; // already logged out
    new GraphRequest(
        new GraphRequest
            .Callback() {
                public void onCompleted(GraphResponse graphResponse)

Include ‘onActivityResult’ option onCreate in same activity:

protected void onActivityResult(int requestCode,
                                int resultCode,
                                Intent data)
      // add this line

Now you are finished with the coding. Run your application in your emulator. You can now login with Facebook also in your application.
