[英]Flutter Scrolling widget inside a Scrolling widget
问题描述
Hello I am building this page https://cdn.discordapp.com/attachments/460823618805563392/526802427836366848/unknown.png 
您好，我正在建立此页面https://cdn.discordapp.com/attachments/460823618805563392/526802427836366848/unknown.png
ListView.builder(
shrinkWrap: true,
itemCount: 1,
itemBuilder: (BuildContext context, int index) {
return new Column(
children: <Widget>[
new RopSayac(MediaQuery.of(context).size.width),
stackvideos(),
],
);
},
)
This is my first listView and there is another listview in stack videos too. 这是我的第一个listView，堆栈视频中也有另一个listview。
new CustomScrollView(
slivers: <Widget>[
SliverFixedExtentList(
itemExtent: 50.0,
delegate: SliverChildBuilderDelegate(
(BuildContext context, int index) {
return new VideoTile();
},
),
),
],
),
Video tile is ordinary component which returns an image and text 视频图块是返回图像和文本的普通组件

And This is the error log 这是错误日志
