我在顶部有一个图像轮播，只希望屏幕/页面的底部滚动，但始终会导致底部溢出。我该如何解决这个问题... ！！
我曾在不同的地方尝试过ListView以及SingleChildScrollView，但无济于事。

我想添加尽可能多的内容，而底部没有溢出。请在这方面帮助我。谢谢。
答案 0 :(得分：0)
我设法弄清楚了，我的问题是我将所有内容包装在一个Column中，该Column的屏幕尺寸只有高度，并且如果内容太多，则无法滚动到超出溢出的范围。主体：是带有轮播容器的圆柱。然后，除此之外，所有内容都包裹在Flexible-> ListView-> Container->列中，然后是Rows以用于内容的不同样式和位置。
