I need to replace my current screen and found replace method in Navigator's API. But I didn't find any example for it. Maybe somebody knows how to use it.

Thanks.

Route route = MaterialPageRoute(builder: (context) => NextPage());
Navigator.pushReplacement(context, route);
Hope it helps
I have never used Navigator.replace() but this  Navigator.pushReplacementNamed might help you.
Navigator.pushReplacementNamed(context, '/thread_list');
                Unfortunately, this method doesn't work. Looks like I should just replace the body of the main widget by setState() method.

                It really works, and for me it was the best solution. Navigator.pushReplacementNamed(context, '/home');

                Navigator.pushReplacement replace current router to new. But it's not clear all history. For example Login -> (Add) Register (Replace) -> Home (Click Back button) -> Login

If you also want to pop all the routes on the Navigator stack, use
Navigator.pushNamedAndRemoveUntil(context, '/page2', (route) => false);
Navigator.pushAndRemoveUntil(context, 
  MaterialPageRoute(builder: (_) => Page2()), (route) => false);
Here the doc of Navigator.dart
Replaces a route on the navigator that most tightly encloses the given context with a new route.
The old route must not be currently visible, as this method skips the animations and therefore the removal would be jarring if it was visible.
To replace the top-most route, consider [pushReplacement] instead, which does animate the new route, and delays removing the old route until the new route has finished animating.
@optionalTypeArgs
  static void replace<T extends Object?>(BuildContext context, { required Route<dynamic> oldRoute, required Route<T> newRoute }) {
    return Navigator.of(context).replace<T>(oldRoute: oldRoute, newRoute: newRoute);
replace method is like
Navigator.replace(
    context,
    oldRoute: MaterialPageRoute(builder: (context) => OlRoute()),
    newRoute: MaterialPageRoute(builder: (context) => NewRoute()),
                copy paste a text from the documentation  doesn't count as an answer, please make your next answer more specific and helpful
