Listener dosen't work

[JackHuang111]

I use it just like the example, but the listener dosen't work

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

  @override
  void dispose() {
    super.dispose();
  }
  void init() async {
    await initScreenshotCallback();
  }

  //It must be created after permission is granted.
  Future<void> initScreenshotCallback() async {
    screenshotCallback = ScreenshotCallback();
    screenshotCallback.addListener(() {
      print("We can add multiple listeners ");
    });
  }
