This is how I did it. First acquire current user. If the user is not logged in the value is null otherwise, the user is logged in.

// Get the firebase user
User firebaseUser = FirebaseAuth.instance.currentUser;
Widget firstWidget;

// Assign widget based on availability of currentUser
if (firebaseUser != null) {
  firstWidget = Home();
} else {
  firstWidget = LoginScreen();
}

// Run the app with appropriate screen
return MaterialApp(
  debugShowCheckedModeBanner: false,
  title: 'UniClass',
  theme: ThemeData(
    primaryColor: kPrimaryColor,
    scaffoldBackgroundColor: Colors.white,
  ),
  home: firstWidget,
);
