flutter - 如何用另一个 GestureDetector 包装 GestureDetector 并在任何地方获取事件

Question

如果我有一个具有内部 GestureDetector 的 GestureDetector，我该如何设置它以便两个检测器都接收到点击事件？

你可以在这里看到运行代码: https://dartpad.dev/37807a51a48e52eda81c24cf67260c33

GestureDetector(
      onTap: () => print("Log 1"),
      child: GestureDetector(
        onTap: () => print("Log 2"),
        child: Text("CLICK ME")
      )
);

• 每次我点击它打印的文本 Log 2。

• 我已经尝试设置 HitTestBehavior.traslucent 和所有这些但没有成功。

• 我希望它打印Log 1 和Log 2

    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);
  }
}
