Login Auth0 - Flutter

Help

I’m developing a mobile app in Flutter and integrating Auth0 Login.

I have an issue on most devices where, when I open the application, an error pops up that I can’t resolve at the root level, and to move forward, I make a new call to the Login method, and then it gets resolved.

I can’t replicate this on iOS or Android emulators! Everything works fine in development; it’s something that happens when installed on devices from the store.

That is, on the first login attempt, the error appears; if I retry the call, it works fine.

The error on iOS is:

error domain com apple authenticationservices webauthenticationservicesession code=3 the uiwindowscene for the returned window was not in the foreground active state

and on Android:

A change on the Lock Screen security settings have deemed the encryption keys invalid and have been recreated. Please try saving the credentials again

@override
void initState() {
  super.initState();
  WidgetsBinding.instance.addPostFrameCallback((_) {
    loadData();
  });
}

Future<void> loadData() async {
  try {
    await dotenv.load();
    final credentials = await ref.read(loginProvider.future);
    credentials.fold((failure) {
      errorCount++;
      if (errorCount <= 3) {
        showAuthExpiredSessionAlert(context: context, fn: loadData);
      } else {
        showAuthErrorAlert(context: context, error: failure, fn: loadData);
      }
      return;
    }, (credential) {
      //Redirect home
      context.go('/home');
      return;
    });
  } catch (e, stackTrace) {
    if (mounted) {
      errorCount++;
      if (errorCount <= 3) {
        showAuthExpiredSessionAlert(context: context, fn: loadData);
      } else {
        showAuthErrorAlert(
            context: context,
            error: Failure(e.toString()),
            stackTrace: stackTrace,
            fn: loadData);
      }
    }
  }
}

As you can see, in the “catch” I show an error message with the retry button, and then the login works correctly 100% of the time.

I haven’t found anything about why this is happening. Any information will be appreciated.
