标签: constrainedbox

我得到一个带有卡片和居中文本的盒子，但是当我减小窗口的大小时，我的卡片消失并且文本溢出。当框小于文本时，出现溢出错误。

我希望最小的盒子尺寸为 300x300，最大的盒子尺寸为 600x600，而不是无限缩小

也许添加 Singlechildscrollview 是我能得到的最好的。我仍然认为有一种方法可以创建缩小到某个最小尺寸的卡片

        class TestConstrainedBox extends StatefulWidget {
  TestConstrainedBox({Key? key}) : super(key: key);

  @override
  State<TestConstrainedBox> createState() => _TestConstrainedBoxState();
}

class _TestConstrainedBoxState extends State<TestConstrainedBox> {
  @override
  Widget build(BuildContext context) {
    return Scaffold(appBar: AppBar(title:Text("Test Constrained Box")),body: 
  SingleChildScrollView(child:
  Container(
      margin: const EdgeInsets.only(top:20.0, left: 20.0, right: 20.0, bottom:10.0),
      child:
      SizedBox.fromSize(size: const Size(450,450),
      //OverflowBox(minHeight:300,minWidth:300,
      //maxWidth:300, maxHeight: 300,
  child:ConstrainedBox(constraints: BoxConstraints(
    minWidth:300,
    minHeight:300,
    maxWidth:350,
    maxHeight:350,
    ),
    child:
    Card(child: 
    Column(mainAxisAlignment: MainAxisAlignment.center,
    crossAxisAlignment: CrossAxisAlignment.center,
    children:[
      //SizedBox(width:350, height:350, child:
           Text('Hello World!')
           //)
           ]))
  
))
     )
    ) …
