The relevant error-causing widget was: Column file:///Users/a1/WORKPLACE/SVNworkplace/t9/lib/view/page/match/match_video_page.dart:1:2159 The overflowing RenderFlex has an orientation of Axis.vertical. The edge of the RenderFlex that is overflowing has been marked in the rendering with a yellow and black striped pattern. This is usually caused by the contents being too big for the RenderFlex.
Consider applying a flex factor (e.g. using an Expanded widget) to force the children of the RenderFlex to fit within the available space instead of being sized to their natural size. This is considered an error condition because it indicates that there is content that cannot be seen. If the content is legitimately bigger than the available space, consider clipping it with a ClipRect widget before putting it in the flex, or using a scrollable container rather than a Flex, like a ListView.

原因：在一个column里嵌套了一个container和一个GridView，Column 是 Flex 组件，是无法滚动的，如果没有足够的空间，flutter就提示溢出错误。
这种情况下，Expanded 或 Flexible 组件可用作长文本的自动换行。
在 Flutter文档中 虽然没有明确说明，但是在主轴上如有内容超出空间， Expanded 和 Flexible 会自动换行到纵轴。
解决：在最外层嵌套SingleChildScrollView或Expanded（实际SingleChildScrollView解决了，Expanded不行）
