Signing user out on 401 in the app with bloc, flutter_bloc and JWT auth.
Hello everyone,​I'm developing an app with bloc and flutter_bloc with JWT authentication and I cannot figure out a good way to sign a user out of the app on 401 error (Unauthenticated).Currently, I have a global Authentication BLoC that controls which screen to show by checking if the token exists in a Secure Storage. For this part, I pretty much followed the tutorial on the bloc package's official website.

 @override Widget build(BuildContext context) { return MaterialApp( home: BlocBuilder<AuthenticationBloc, AuthenticationState>( builder: (context, state) { if (state is AuthenticationAuthenticated) { return HomeScreen(); } if (state is AuthenticationUnauthenticated) { return LoginPage(); } if (state is AuthenticationLoading) { return LoadingIndicator(); } return SplashPage(); }, ), ); } 

In my services, I use Dio to make requests with some interceptors attached that add the auth header to requests and catch 401 errors.

 static dynamic errorInterceptor(DioError dioError) { if (dioError.response.statusCode == 401) { return UnauthorizedException("Unauthorized", dioError); } } 

Currently, all my other BLoCs that need to make network requests(via repositories -> services) have a dependency on AuthenticationBloc and try-catch blocks that check if the error is an instance of UnauthorizedException, then Logout event is sent to AuthenticationBloc that practically kicks the user out to login screen and removes the token from storage.It doesn't seem like a very good solution to me, considering the fact that most of the BLoCs will be dependent on AutheticationBloc.What would be the best approach for my use case?

Tables with Listview.builder
Is there any plugin which uses listview.builder to create tables with fixed header and column . I am currently using this https://pub.dev/packages/table_sticky_headers but because of too much data the table load very slow . Would also like to add bidirectional scrolling , search function and highlight row and column feature . I have not seen any plugin which meets all criteria .
