I'm developing an app with Flutter. I'm using flutter_native_splash right now, I'm trying to create a splash screen with a background image. At this time, what size of the splash image should be specified? Can I implement two splash screens, iOS and Android, with one image?
You can use one image to implement a splash screen for both iOS and Android. When you use a flutter_native_splash package, then you have to configure it in the pubspec.yaml file, which is the place where you need to configure this package.
