You can to check and request permission checkPermission work to android, ios coming soon bro.

    Future<void> _checkPermission() async {
    _screenshotDetect.checkPermission().then((isGranted) {
      if (isGranted == null || !isGranted) {
        _screenshotDetect.requestPermission();
      }
    });
  }

Create Stream of Screenshot stream and listen call back

    Future<void> _listenScreenShot() async {
    _stream = _screenshotDetect.screenShotStream();

    _stream.listen((String? path) {
      print("It is a path screenshot!\n $path");
    }).onError((error) {
      print("It is somethings wrong: \n $error");
    });
  }

Full example:

class _MyAppState extends State<MyApp> {
  final ScreenshotDetect _screenshotDetect = ScreenshotDetect();
  late Stream<String?> _stream;

  @override
  void initState() {
    super.initState();
    _checkPermission();
    _listenScreenShot();
  }

  Future<void> _checkPermission() async {
    _screenshotDetect.checkPermission().then((isGranted) {
      if (isGranted == null || !isGranted) {
        _screenshotDetect.requestPermission();
      }
    });
  }

  Future<void> _listenScreenShot() async {
    _stream = _screenshotDetect.screenShotStream();

    _stream.listen((String? path) {
      print("It is a path screenshot!\n $path");
    }).onError((error) {
      print("It is somethings wrong: \n $error");
    });
