void main() {

  const MyApp({Key? key}) : super(key: key);

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

class _MyAppState extends State<MyApp> {

  @override
  void initState() {
    super.initState();
    initPlatformState();
  }

  Future<void> initPlatformState() async {
    await Permission.camera.request();
    await Permission.microphone.request();

    // Set up AVAudioSession for iOS.
