Flutter 错误：The method ‘＞‘ was called on null
不说废话，直接上方法：
一般是ListView 搭配 Row 或者 Colunm错误，直接在Row 或者Colunm的子组件中使用Expand组件即可
这是正确的，不报错的
return Container(child: Row(children: <Widget>[Expanded(child: ListTile(title: Text(titleName,style: TextStyle(color: Colors.black,fontWeight: FontWeight.w500,fontSize: 16.0),),subtitle: Text(subTitle),),)],),);这是错误的，
