下面的代码在不使用 Row 小部件的情况下工作，但是它在使用带 Row 的嵌套 ListView 时出错 如果这是我在上面代码中的用例，我如何使用 Row 我有一行，其中有两列

Widget build(BuildContext context) {
// TODO: implement build
return Scaffold(
  appBar: AppBar(
    title: Text("Dashboard"),
    actions: <Widget>[
      IconButton(
        icon: Icon(Icons.add_circle),
        iconSize: 50.0,
        onPressed: () {
          Navigator.push(
            context,
            MaterialPageRoute(
              builder: (BuildContext context) => AddMember(),
            ),
          );
        },
      ),
    ],
  ),
  drawer: MainDrawer(),
  body: Container(
    decoration: BoxDecoration(
      image: Background().buildBackgroundImage(),
    ),
    child: ListView(
      children: <Widget>[
        Row(
          children: <Widget>[
            Column(
              children: <Widget>[
                Text("1"),
              ],
            ),
            Column(
              children: <Widget>[
                Text("Hammad"),
                ListView.builder(
                  shrinkWrap: true,
                  physics: ClampingScrollPhysics(),
                  itemBuilder: (BuildContext context, int index) {
                    return Text("data");
                  },
                  itemCount: 100,
                ),
              ],
            ),
          ],
        )
      ],
    ),
  ),
);

  } }

代码出现如下错误？

最佳答案

使用灵活的小部件包装您的列。

Flexible(
           child: Column(
           children: <Widget>[

关于Flutter Nested Listview 为什么我不能使用行？，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/53148038/
