UI doesn't react to state changes after using Navigator.push about bloc HOT 4 CLOSED

This is not an issue with Bloc but with your design.

You have your bloc above MaterialApp, which is great -- all pages can access it.

Imagine routes/pages as "papers" and widgets as "drawings" on that paper. Based on what you described, your pages are Home Page and Second Page. On page Home there might be "drawings" welcome or first. That means when you are on Home Page, you can actually see bloc builder to build something.

But when you navigate to Second Page, again imagine a paper, you cannot see changes on Home Page, but only your current page, no matter if Home Page actually still exists or not. So if you want to create navigation based on states, you need to choose different approach, since your does not do that.

I would recommend i.e. creating states based on auth state like AuthInProgress, LoggedIn and UserNeedsToLogin etc. and then you have two options.

Use BlocListener under provider (you may need Builder above BlocListener to provide current context) and listen to changes there and there you can redirect to different pages (display different "papers"), or you can use something like GoRouter package which I recommend anyway and GoRouter object has redirect callback which you can implement like this maybe, you get the point...

MyStates? lastState;

FutureOr<String?> handleRedirect(
    BuildContext context,
    GoRouterState state,
  ) {
    final appState = context.read<MyBloc>().state;

    // Same route.
    final isSameState = appState == lastState;
    if (isSameState) {
      return null;
    }
    lastState = appState;

    // Auth in progress.
    if (appState is AuthInProgress) return null;

    if (appState is UserNeedsToLogin) {
      return '/login';
    }
    
    return null;

I hope you understand the concepts why your solution couldnt do that thing you wanted. Feel free to ask more questions for sure. :)

I have the same problem and I couldn't find the solution. 🤔🤔🤔

I've had the same problem for about 2 weeks and I still haven't resolved it...

Thank you very much for your early answer. So, I think that in conclusion is not a good idea to think about screens as if they were states. I'm currently redesigning my app.
