具有项目高度的ListView.builder

Question

我有一个具有动态内容的ListView，我希望每个项目都根据其内容具有动态高度，但是如果我没有为每个项目都设置一个固定高度，则会出现错误

package：flutter / src / rendering / sliver_multi_box_adaptor.dart'：失败的断言：549行pos 12：'child.hasSize'：不正确。

这是ListView itemBuilder的完整布局：

return Container(
  key: _key,
  // If I set height: 500 here it works
  child: InkWell(
    onTap: () => _cardTap(_key, context, house),
      child: Card(
        shape: RoundedRectangleBorder(
          borderRadius: BorderRadius.circular(16.0),
        ),
        semanticContainer: true,
        clipBehavior: Clip.antiAliasWithSaveLayer,
        elevation: 4,

如何获取物品（容器，卡片或问题列）以达到显示其内容所需的高度？

谢谢
