我对Stack Widget有个问题。我有一个包含两个子元素的堆栈:一个用GestureDetector包装的图像和一个容器。当我在容器上的任意位置单击时，堆栈子列表中的最后一个人将列出其onTap
我对flutter还是个新手。

这段代码
sonItem(dynamic icon ,String text,Color color){
return GestureDetector(
onTap: () {
print("dddddddddddddddd");
},
child: Container(
width: 70,
height: 100,
margin: EdgeInsets.all(2),
padding: EdgeInsets.all(2),
child: Column(
children: [
Icon(icon ,color: color,),
Text(text)

);}
