android - 使用ListTile并获取异常:未布局RenderBox

Question

我正在尝试在列和行中使用ListTile()，但是它引发了异常:

Exception caught by rendering library 
The following assertion was thrown during performLayout():
BoxConstraints forces an infinite width.

这是代码:

          Row(
            children: <Widget>[
              Column(
                children: <Widget>[
                  Card()
                ],
              ),
              Column(
                children: <Widget>[
                  Card(
                    child: ListTile(),
                  )
                ],
              )
            ],
          ),

我们该如何解决呢？

使用扩展的小部件

       Row(
            children: <Widget>[
              Column(
                children: <Widget>[
                  Card()
                ],
              ),
              Expanded(
                child: Column(
                  children: <Widget>[
                    Card(
                      child: ListTile(),
                    )
                  ],
                ),
              )
            ],
          ),
