FlutterListView使用异常

异常：Vertical viewport was given unbounded height

解决：添加shrinkWrap: true

return Column(         children: <Widget>[           ListView.builder(               itemCount: sourceDataComments.length,               itemBuilder: _buildCommentsRow,               shrinkWrap: true,           ),         ],       ); ​​​​​​​

异常：（ListVIew嵌套在Column中）布局溢出，ListView无法滚动界面显示不全，异常代码如下

Widget build(BuildContext context) { return Container( child:RefreshIndicator( color: const Color(0xFF4483f6), child: ListView.builder( itemCount: linkList.length, itemBuilder: (context, index) { return Text(linkList[index].title); }, shrinkWrap: true, controller: _controller, ), onRefresh: _pullToRefresh, ), ); }

解决：在外面嵌套一个Expand，尺寸计算导致，expande就是listview有多大就有多大

Widget build(BuildContext context) { return Container( child: Expanded( child: RefreshIndicator( color: const Color(0xFF4483f6), child: ListView.builder( itemCount: linkList.length, itemBuilder: (context, index) { return Text(linkList[index].title); }, shrinkWrap: true, controller: _controller, ), onRefresh: _pullToRefresh, )), ); }
