How to run Flutter's Build with Theta sample app

Future<void> main() async {
  /// Initialize Theta instance.
  /// You can get an anonymous key at https://app.buildwiththeta.com
  await Theta.initialize(anonKey: 'Theta Key');

  runApp(const MyApp());

  @override
  State<MyApp> createState() => _MyAppState();
}

    super.initState();
    _controller.onLoaded(() {
      debugPrint('Loaded!');
    });
    _controller.onError((error) => debugPrint(error.toString()));
  }

  @override
  void dispose() {
    _controller.dispose();
    super.dispose();
  }
