Flutter：如果 child 被点击，从 parent 和 child 触发 ontap/onpressed

Question

我有一个 GestureDetector 和很多孩子，例如 TextButtons。如果按下一个按钮，我想从 Gesturedetector 和一个按钮触发 ontap。在下面的例子中，如果我按下按钮 1，输出应该是

Button 1 tap
GestureDetector tap

我尝试更改 GestureDetector 的行为，但没有任何效果。

class MyHomePage extends StatelessWidget {
  MyHomePage({Key? key, required this.title}) : super(key: key);

  final String title;

  @override
  Widget build(BuildContext context) {
    return GestureDetector(
      onTap: () => print("GestureDetector tap"),
      child: Scaffold(
          appBar: AppBar(
            title: Text(title),
          ),
          body: Column(
            children: [
              TextButton(
                child: Text("Button 1"),
                onPressed: () => print("Button 1 tap"),
              ),
              TextButton(
                child: Text("Button 2"),
                onPressed: () => print("Button 2 tap"),
              )
            ],
          )
          ),
    );
  }
}

我可以写一个方法并将其放入所有 onTap/onpressed，但我想我遗漏了一些东西。

Answer 1

我找到了属性 onTertiaryTapDown。

...This is called after a short timeout, even if the winning gesture has not yet been selected....

class MyHomePage extends StatelessWidget {
  MyHomePage({Key? key, required this.title}) : super(key: key);

  final String title;

  @override
  Widget build(BuildContext context) {
    return GestureDetector(
      onTertiaryTapDown: (tapDownDetails) =>{ print("GestureDetector tap")},
      child: Scaffold(
          appBar: AppBar(
            title: Text(title),
          ),
          body: Column(
            children: [
              TextButton(
                child: Text("Button 1"),
                onPressed: () => print("Button 1 tap"),
              ),
              TextButton(
                child: Text("Button 2"),
                onPressed: () => print("Button 2 tap"),
              )
            ],
          )
          ),
    );
  }
}
