After you register for the developer account, the first most important thing you need to do is register a Bundle ID. Every iOS app is associated with a Bundle ID, which is a rare identifier registered with Apple.

  1. On the official Apple developer account select “Certificates Identifiers and Profiles”. On the left side, the menu selects “Identifiers”.
  2. Click “+” to create a Bundle ID. Select “App ID” on the next following page and select continue.

Now, you can download the zip file and extract it. Next, you can found that a file named “AppIcon.appiconset” inside the “Assets. cassettes” folder. Copy this file and open the flutter project on your Android studio. Select the iOS file in the project directory called your_project_name/ios/Runner/Assets.cassettes/AppIcon.appiconset. Paste and change the copied folder in the given location.

You can change the screen by removing “LauncherImage” with “LaunchImage.images”. Apple has provided the instructions on its official page, Please take an effort to read it.

How to do the app store connect listing process?

Next, you have to go through the apple store connection and select "my App." Select on the “+” icon to create the App. On the pop-up window, write the App name, select language, select the Bundle ID that you made in the last step, and write SKU.
