Launch screens provide a simple initial experience while your iOS app loads. They set the stage for your application, while allowing time for the app engine to load and your app to initialize.

All apps submitted to the Apple App Storemust provide a launch screen with an Xcode storyboard.

The default Flutter template includes an Xcode storyboard namedLaunchScreen.storyboard that can be customized with your own assets. By default, the storyboard displays a blank image, but you can change this. To do so, open the Flutter app's Xcode project by typingopen ios/Runner.xcworkspace from the root of your app directory. Then selectRunner/Assets.xcassets from the Project Navigator and drop in the desired images to theLaunchImage image set.

Apple provides detailed guidance for launch screens as part of theHuman Interface Guidelines.
