-# Launch Screen Assets
-
-You can customize the launch screen with your own desired assets by replacing the image files in this directory.
-
-You can also do it by opening your Flutter project's Xcode project with `open ios/Runner.xcworkspace`, selecting `Runner/Assets.xcassets` in the Project Navigator and dropping in the desired images.
