late final FirebaseApp firebaseApp;

void main() {
  WidgetsFlutterBinding.ensureInitialized();
  Firebase.initializeApp()
      .then((app) => firebaseApp = app)
      .then((_) => FirebaseAppCheck.instance.activate(
          webRecaptchaSiteKey: '6LdRiP8cAAAAAAcplxBPieXdqrKy0-S2c9pYq1yC'))
      .then((_) {
    print("App: $firebaseApp");
  }).then((_) => runApp(GetMaterialApp(
            title: "MyGuide",
            themeMode: ThemeMode.system,
            theme: ThemeData(),
