Can you add a video of the splash screen? I don't understand what is happening.

I already added it.( it is showing by URL ..! )

Screen_Recording_20241108_113939_One.UI.Home.mp4

FlutterNativeSplash.remove() is commented to test.

I think you may need to follow these instructions:

https://docs.flutter.dev/release/breaking-changes/splash-screen-migration

I read all the documents, but there was nothing relevant.

I don't know why not.. 🥲

Thank you for your help.

From what I can see, it seems to be an issue due to an error that does not stop on the splash screen despite calling the function FlutterNativeSplash.preserve(widgetsBinding: widgetsBinding).

Is there a particular case where the preserve() function doesn't work?

here is my code.

void main() {
  _init();
}

_init() async {
  final WidgetsBinding widgetsBinding = WidgetsFlutterBinding.ensureInitialized();
  FlutterNativeSplash.preserve(widgetsBinding: widgetsBinding);
  print('preserve');

  if (!(await InternetConnectionChecker().hasConnection)) {
    //인터넷연결페이지
    runApp(const InternetCheckMain());
    return;
  }

  if ((await ApiCheckService.instance.apiCheck()) == 0) {
    runApp(const ApiCheckMain());
    return;
  }

  await _initSharedPreferences();
  ....... setting ....... 
  await ....
  await ...

  FlutterNativeSplash.remove();
  print('remove');

  runApp(const MainApp());
}

Problem is in MainActivity.kt .

I just comment this line.

class MainActivity: FlutterActivity() {
    // override fun onCreate(savedInstanceState: Bundle?) {
    //     intent.putExtra("background_mode", "transparent")
    //     super.onCreate(savedInstanceState)
    // }
}
