Flutter - Encountered a Error at an unrecoverable point. Failure was:

[constantinLu]

Description
Sorry about labeling a bug, but I could not find any related label for my issue.
Error saying string value of a bloc state is empty, but when looking into the bloc observer the states are mapped correctly.

Steps To Reproduce

The problem that I have is that The BLocBuilder from AddressView it does not take into account the newly updated state.

From my undestanding is that the bloc state is updated to late since the BlocBuilder still takes the old value. (the empty value)

Class where the exception is thrown: AccountView.

Bloc is Provided in the app_widget.dart , then I add an event to the satefull class AccountView -> and build the view. (Crashes on the BlocBuilder).

In the BlocObserver the state changes correctly but when it reaches the BlocBuilder the initial value is taken into account and not the newly changed state with the initialized values.

class AppWidget extends StatelessWidget {
  static const String title = 'Vault Pass';

  const AppWidget({super.key});

  @override
  Widget build(BuildContext context) {
    final _appRouter = getIt<AppRouter>();

    /// PROVIDES ACCESS TO BLOCS TO THE CHILDREN
    return MultiBlocProvider(
      providers: [
        BlocProvider(
            create: (context) =>
                //adds event right away! with ..add()
                getIt<AuthBloc>()..add(const AuthEvent.authCheckRequest())),
        BlocProvider(create: (context) => getIt<RegisterBloc>()),
        BlocProvider(create: (context) => getIt<LoginBloc>()),
        BlocProvider(create: (context) => getIt<RecordBloc>()),
      ],
      child: MaterialApp.router(
        routerDelegate: _appRouter.delegate(),
        routeInformationParser: _appRouter.defaultRouteParser(),

Expected Behavior

• should map the next mapped state values
