Basic usage

void main() => runApp(MyApp());

class MyApp extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    return ChangeNotifierProvider<AuthState>(
      child: MaterialApp(
        home: ParentPage(),
      ),
      create: (_) => AuthState(),
    );
  }
}

3. The AuthManagerWidget manages the screen shown in each of the authentication states

class ParentPage extends StatelessWidget{
  @override
  Widget build(BuildContext context) {
    return AuthManagerWidget(
      splashScreen: MySplashScreen(), //optional
      introductionScreen: MyIntroductionScreen(), //optional, user not logged
      loginScreen: MyLoginScreen(), // user not logged, the introduction has been completed
      mainScreen: MyMainScreen(), // user logged (email, google, apple or anonymous)
    );
  }
}
