    You should add your Firebase project to your Flutter App.
    Here is the link how to do that https://firebase.google.com/docs/flutter/setup?platform=web.
    After adding it properly, Firebase generates a config file then your code will be

    void main() async {
  WidgetsFlutterBinding.ensureInitialized();
  await Firebase.initializeApp(
     options: DefaultFirebaseOptions.currentPlatform,
  );
  runApp(const MyApp());
}

    Hope this helps.

    In addition to above answer that’s because

    await Firebase.initializeApp();

    is deprecated so becareful (Most of the content is using the old way).
