颤动中的容器
希望你们一切都好。我正在制作一个颤振应用程序。在这个界面中我遇到了问题。我正在制作一个堆栈中的容器和圆形头像。在堆栈中,第一个小部件容器中还有另一个容器。当我将图像设置为内部容器的子项时,它也适用于外部容器。为什么会出现这种情况以及这个问题的解决方案是什么。
Stack(
children: [
// Container(child:
Container(
decoration: BoxDecoration(
border: Border.all(
color: Colors.indigo,
)),
width: 340,
height: 200,
child: Container(
child: Image.asset(
'assets/pic1.jpg',
fit: BoxFit.cover,
),
width: 340,
height: 150,
decoration: BoxDecoration(
border: Border.all(
color: Colors.black,
)),
),
),
Positioned(
bottom: 10,
right: 10,
child: CircleAvatar(
backgroundColor: Colors.grey,
radius: 40,
))
],
)
Hope you all are doing well. I am making a flutter application. In this interface I am having a issue. I am making a container and circle avatar which are in stack. In stack, in first widget container there is also another container. When I set image as a child to inner container it also applied to outer container. Why is this happening and what is the solution of this problem.

我认为您只需要将属性对齐到您的父窗口小部件,否则子窗口小部件将不关心高度和宽度

I think You just need to Alignment Property to your Parent widget otherwise child widget will not care about height and width
