How to pass data to another window and forbid going back?

Question

Dart

I have 2 windows. The first one is, for example, loginScreen() . In it, I want to go to the second mainScreen() window and pass data there:

Navigator.push(
    context,
    MaterialPageRoute(
        builder: (context) => MainScreen(token: "qwerty"),
    )
);

But because of Navigator.push , a back button appears on the top left.

I read that this button can be removed using

AppBar(
    automaticallyImplyLeading: false
)

But then when you press the hardware back button, it still returns to the first loginScreen() window. How do I change the window then?

Answer 1

use pushReplacement instead of push
then automaticallyImplyLeading: false is not needed
