当我在ListView内创建带有框阴影的容器（水平滚动）时，阴影看起来很好，但是，当我在ListView内添加多个Container时，其阴影（只是阴影，不是Container）在顶部和底部被裁剪
请注意，整个ListView都包装在父容器下。
我试图增加父容器的高度（包裹整个ListView），但是它增加了子容器的高度，并且阴影仍然被裁剪。
我也尝试给父容器添加填充，但是仍然阴影仍然被裁剪。
也许我需要将ListView包裹在任何其他Widget中，这样才能顺利完成工作。

我希望ListView的Containers（作为自定义卡）具有适当的BoxShadow，但在实际输出中，Container的BoxShadow将从顶部和底部开始裁剪。
答案 0 :(得分：7)
正如@Zahra 所写，
将 clipBehavior: Clip.none, 添加到 ListView，解决了问题。
仅当您的小部件超过屏幕尺寸时才会发生裁剪
答案 1 :(得分：0)
好的，我自己找到了解决方法。
解决问题的步骤
创建一些具有一定宽度并具有Radius 10.0的BoxShadow的容器（作为卡）。我们称之为子容器。
使用水平滚动轴创建ListView。将上面制作的子容器放入此ListView。
现在将ListView包裹在一个新的Container中（称为父容器），以赋予ListView一个高度。如果您希望子容器的高度为140.0，则使父容器的高度为160.0，其中上下分别包含BoxShadow的半径为10.0（10.0+ 140.0 + 10.0）。
现在为顶部和底部的10.0的ListView提供填充。
问题已解决（Silly Me）。
