Flutter常見問題－RenderFlex overflowed

I/flutter (15792): ══╡ EXCEPTION CAUGHT BY RENDERING LIBRARY ╞═════════════════════════════════════════════════════════
I/flutter (15792): The following assertion was thrown during layout:
I/flutter (15792): A RenderFlex overflowed by 24 pixels on the bottom.
I/flutter (15792):
I/flutter (15792): The relevant error-causing widget was:
I/flutter (15792):   Column file:///C:/Users/AndroidStudioProjects/lib/pages/firstpage.dart:34:11
I/flutter (15792):
I/flutter (15792): The overflowing RenderFlex has an orientation of Axis.vertical.
I/flutter (15792): The edge of the RenderFlex that is overflowing has been marked in the rendering with a yellow and
I/flutter (15792): black striped pattern. This is usually caused by the contents being too big for the RenderFlex.
I/flutter (15792): Consider applying a flex factor (e.g. using an Expanded widget) to force the children of the
I/flutter (15792): RenderFlex to fit within the available space instead of being sized to their natural size.
I/flutter (15792): This is considered an error condition because it indicates that there is content that cannot be
I/flutter (15792): seen. If the content is legitimately bigger than the available space, consider clipping it with a
I/flutter (15792): ClipRect widget before putting it in the flex, or using a scrollable container rather than a Flex,
I/flutter (15792): like a ListView.
I/flutter (15792): The specific RenderFlex in question is: RenderFlex#851d4 relayoutBoundary=up2 OVERFLOWING:
