未处理的异常：无法测试没有大小的渲染框

所以我正在尝试重新创建一个 UI 模板。这是代码。我试图通过调用RecentlyViewed() 添加另一个水平GridView，但重新加载后它无法呈现。我不知道如何渲染它。我尝试过使用扩展的小部件和灵活的但都不起作用

return Scaffold(

这是显示的错误：

有人可以帮助我通过使整个屏幕可滚动来渲染我的小部件 idk

For a ListView, set 收缩包装财产给true

shrinkWrap: true

为什么需要这个？

ListView总是尝试填充父元素给出的所有可用空间。 因此，假设父级是一个列，那么我们知道该列占用最大可用高度，因此如果您的列表较长，那么您就会遇到问题，因为没有足够的可用空间。如果列表较小，那么它会尝试填充可用空间，即使它不能。

With shrinkWrap: true，您可以更改此行为，以便 ListView 只占用它需要的空间（当有更多项目时它仍然会滚动）。
