I want to navigate to next screen then do not back to any screen, but when I use Navigator.pushReplacement my app has back button. I mean, arrow back key still work. I want to go to next screen totally, and no back.

Hope anyone help me.

This is my code

return BlocProvider<PostBloc>(
      create: (BuildContext context) => postBloc..add(CreatePostStartEvent()),
      child: Scaffold(
        body: BlocConsumer<PostBloc, PostState>(
          listener: (context, state) async {
            if (state is PostCreationSuccessState) {
              Navigator.pushReplacement(
                  context, MaterialPageRoute(builder: (context) => const Posts()));
            }
          },
      ...

```
Navigator.popAndPushNamed(context, '/second');
```
This method pops the current route and pushes a new named route.

If you need to clear all screens in the navigation stack and push a new one in Flutter, you can use the Navigator.of(context, rootNavigator: true).pushNamedAndRemoveUntil method. This will remove all existing routes and push the specified route as the new one.
```
   Navigator.of(context, rootNavigator: true)
                .pushNamedAndRemoveUntil(
              '/home',
              (_) => false,
            );
```
- Navigator.of(context, rootNavigator: true): This accesses the navigator of the root context.
- .pushNamedAndRemoveUntil('/home', (Route<dynamic> route) => false): This method removes all the routes until the given predicate returns true. The predicate (Route<dynamic> route) => false always returns false, ensuring that all routes are removed. Then, it pushes the new route specified by the name ‘/home’.
  This approach is useful when you want to reset the navigation stack and start a fresh with a new screen.
