If you are going to use the FirebaseUser and want to keep track of the state or Logged in user throughout your app, i would suggest that you use the Provider on the highest level of your app. For me its the easiest using the Provider Package [LINK] which is basically ScopedModel v2 according to some tutorials/videos Example void main() { runApp(MyApp()); } class MyApp extends StatelessWidget { MyApp(); @override Widget build(BuildContext context) { return MultiProvider( providers: [ StreamProvider<FirebaseUser>.value( stream: FirebaseAuth.instance.onAuthStateChanged, // Provider here ), ], child: MaterialApp( title: 'My App', debugShowCheckedModeBanner: false, theme: ThemeData( primaryColor:

The Provider package can be very useful for using data transmitted between screens and widgets. The package: [LINK] For example, I use this package to transmit auth and storage data between my screens without the need of passing the same argument for the next screen and the next one so on.

So instead of using a Streamprovider, you would use a FutureProvider where you would call the getFontSize function inside of.
