Why is removeListen commented out?

[greatcr7]

Trying to remove the listener under dispose but can't....

[JasonSleigh]

Have you managed to find a way to do this? I have used a box.listenKey((value) {}); .. but when I try to dispose as per documentation eg: box.removeListen(listen); I get a syntax error telling me that get_storage does not have a function called removeListen ?? please help as now I have set state braking when trying to dispose the widget.

addListener return the dispose function

var dispose = addListener(...

dispose.call() or dispose()

solution:

  Function? disposeListen;

  @override
  void initState() {
    GetStorage getStorage = GetStorage();
    disposeListen = getStorage.listenKey('my_key', (value) {
      //your code here
    });
    super.initState();
  }

  @override
  void dispose() {
    disposeListen?.call();
    super.dispose();
  }
