我无法在表单上滚动，如何解决滚动问题：下面的代码和错误。
\n来自终端的错误:\n\xe2\x95\x90\xe2\x95\x90\xe2\x95\x90\xe2\x95\x90\xe2\x95\x90\xe2\x95\x90\xe2\x95\x90\ xe2\x95\x90 渲染库捕获异常 \xe2\x95\x90\xe2\x95\x90\xe2\x95\x90\xe2\x95\x90\xe2\x95\x90\xe2\x95\x90\xe2\x95 \x90\xe2\x95\x90\xe2\x95\x90\xe2\x95\x90\xe2\x95\x90\xe2\x95\x90\xe2\x95\x90\xe2\x95\x90\xe2\x95\x90 \xe2\x95\x90\xe2\x95\x90\xe2\x95\x90\xe2\x95\x90\xe2\x95\x90\xe2\x95\x90\xe2\x95\x90\xe2\x95\x90\xe2 \x95\x90\xe2\x95\x90\xe2\x95\x90\xe2\x95\x90\xe2\x95\x90\xe2\x95\x90\xe2\x95\x90\xe2\x95\x90\xe2\x95 \x90\xe2\x95\x90\n布局期间抛出以下断言：\nRenderFlex 底部溢出 179 像素。
\n导致错误的相关小部件为\nColumn\nlib\\auth\\signupBasicDetails.dart:254\n溢出的 RenderFlex 的方向为 Axis.vertical。\n溢出的 RenderFlex 的边缘已在渲染中用黄色和黑色条纹图案。这通常是由于内容对于 RenderFlex 来说太大造成的。
\n考虑应用弹性因子（例如使用 Expanded widget）来强制 RenderFlex 的子级适应可用空间，而不是调整其自然大小。\n这被视为错误情况，因为它表明存在无法容纳的内容。可见。如果内容确实大于可用空间，请考虑在将其放入 Flex 之前使用 ClipRect 小部件对其进行剪辑，或者使用可滚动容器而不是 Flex，例如 ListView。
\n有问题的具体 RenderFlex 是：RenderFlex#d8c43 relayoutBoundary=up2 OVERFLOWING

您可以用 包裹column起来SingleChildScrollView。
SingleChildScrollView(
child: Column(
...
),
),
