How to wrap GestureDetector with another GestureDetector and get events everywhere

    class _MyAppState extends State<MyApp> {
  @override
  Widget build(BuildContext context) {
    return RawGestureDetector(
        gestures: {
          AllowMultipleVerticalDragGestureRecognizer: GestureRecognizerFactoryWithHandlers<
              AllowMultipleVerticalDragGestureRecognizer>(
            () => AllowMultipleVerticalDragGestureRecognizer(),
            (AllowMultipleVerticalDragGestureRecognizer instance) {
              instance..onEnd = (_) => print("test1");
            },
          )
        },
        child: RawGestureDetector(
          gestures: {
            AllowMultipleVerticalDragGestureRecognizer: GestureRecognizerFactoryWithHandlers<
                AllowMultipleVerticalDragGestureRecognizer>(
              () => AllowMultipleVerticalDragGestureRecognizer(),
              (AllowMultipleVerticalDragGestureRecognizer instance) {
                instance..onEnd = (_) => print("test2");
              },
            )
          },
          child: Container(color: Colors.red),
        ));
  }
}

class AllowMultipleVerticalDragGestureRecognizer extends VerticalDragGestureRecognizer{
  @override
  void rejectGesture(int pointer) {
    acceptGesture(pointer);
  }
}

    If I have a GestureDetector that have an internal GestureDetector how can I setup it so that both detectors receive the click event?

    You can see the running code here: https://dartpad.dev/37807a51a48e52eda81c24cf67260c33

    GestureDetector(
          onTap: () => print("Log 1"),
          child: GestureDetector(
            onTap: () => print("Log 2"),
            child: Text("CLICK ME")
          )
    );
    
    • Every time I click the text it prints Log 2.

    • I already tried setting HitTestBehavior.traslucent and all of them but got no success.

    • I want it to print Log 1 and Log 2
