Flutter api颤振中的水平listview生成器

如何创建从dart对象类（即API）获取数据的水平listview

代码如下：

return MaterialApp(
      home: Scaffold(
        appBar: AppBar(
          title: Text("practice"),
        ),
        // child: Text("data")
        body:Container(
           child: ListView.builder(
           scrollDirection: Axis.horizontal,
           itemCount: l1.length,
           itemBuilder: (context , index){
              return ListTile(
                     title: Image.network(l1[index]),
                     subtitle: Text(l2[index]),
               );

我得到这个错误：

RenderBox was not laid out: RenderPointerListener#784b4 relayoutBoundary=up8 NEEDS-PAINT NEEDS-COMPOSITING-BITS-UPDATE
'package:flutter/src/rendering/box.dart':
Failed assertion: line 1694 pos 12: 'hasSize'

列表视图应包装在具有高度的容器中，向容器添加高度可能会解决此问题

body:Container(
       height: 100,
       child: ListView.builder(
       scrollDirection: Axis.horizontal,
       //Rest of your code

参考此，添加两个信息1。为l1和l2变量赋值的代码。2.完整的错误堆栈。如果l1和l2使用api调用填充，我建议也研究StreamBuilder和FutureBuilder。
