How to navigate other routes from nested screen ?

[imjeen]

There are some screen page under the root of app,
and they are not in tabs. Such as Login Screen.

I Try to try to navigate to these screen page by the way: Navigator.of(context).pushNamed('/login'); but it cannot.

Finally, I found a way to resolve it.

Navigator.of(context, rootNavigator: true)
    .pushNamedAndRemoveUntil(
  LoginScreen.routeName,
  (_) => false,
);
