See the code sample from Flutter's Firebase documentation

If you initialize Firebase in your app's entry, you can guarantee that it has both been initialized and only one time.

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