Issues with #16. Authenticating Users with FirebaseAuth

[FredWolfe]

does anyone have the update of this tutorial, this process is old and so my register screen cannot navigate into the chat screen, tried to follow all the processes of migrating and updating deprecated codes but still no avail. I am literally going nuts here.
I keep seeing this in the run Console;
"Ignoring header X-Firebase-Locale because its value was null."
what is this and how do i fix it, better still has anyone passed this tutorial epsiode in 2020, current day. Pleaassse help me, I am new to flutter programming

Future<void> main() async {
  WidgetsFlutterBinding.ensureInitialized();
  await Firebase.initializeApp();
  runApp(FlashChat());
}

Add this to main.dart and also import firebase core library
