flutter - 我该如何解决这个错误（A RenderFlex 在底部溢出了 104 个像素。）

Question

在此处输入图像描述

这（在 ListTile 内尾随）在 Flutter 中

trailing: Column(
            children: <Widget>[
              new IconButton(icon: Icon(Icons.arrow_drop_up), onPressed: (){}),

              Text("Hello"),
              new IconButton(icon: Icon(Icons.arrow_drop_down), onPressed: (){}),


            ],
          ),

 trailing: Column(
          mainAxisAlignment: MainAxisAlignment.start,
          mainAxisSize: MainAxisSize.min,
          children: <Widget>[
            Expanded(
                  child: new IconButton(
      padding: EdgeInsets.zero,
      icon: Icon(Icons.arrow_drop_up), onPressed: (){}),
            ),

            Expanded(child: Text("Hello")),
            Expanded(child: new IconButton(icon: Icon(Icons.arrow_drop_down), onPressed: (){})),


          ],
        ),
