Putting the Widget in a Scaffold solved this for me.

Before:

Navigator(
  onGenerateRoute: (settings) {
    if (settings.name == '/...') {
      return MaterialPageRoute(   
        builder: (context) => NestedScrollView(..)
      );
    }
  }
)

After:

Navigator(
  onGenerateRoute: (settings) {
    if (settings.name == '/...') {
      return MaterialPageRoute(   
        builder: (context) => Scaffold(
          body: NestedScrollView(..)
        ),
      );
    }
  }
)

I was experiencing this lag as well, running debug mode on chrome. Despite not having any lag on debug mode in a emulator.

Running chrome on profile mode, as @Lunedor suggested, seems to eliminate all these performance issues.

push or pushNamed doesn't close current screen if you want to new screen get replace(not on) your current screen you need to use pushReplacement or pushReplacementNamed method

so try below code and check methods in flutter documents to get the whole idea about navigation:

Navigator.pushReplacementNamed(context, '/RegisterScreen');
