Start with the iOS asset path ios/[project name]/Images.xcassets/LaunchImage.launchimage and inspect the listed launch image files and Contents.json structure. Add the iOS launch-screen assets described in the issue, with the listed device sizes, orientations, and minimum system versions; done means the launch screen is represented by that asset catalog.
