设计这张卡片的最佳方式是什么？我用行和列完成了此操作，但当我在出现键盘时单击此功能生成器下方的文本字段时，它会导致像素溢出等问题。汽车图像后面的Flexible行导致溢出，我不知道为什么!它已经在灵活的小部件中了。如果我不单击文本字段，它就可以正常工作。请指导我。 FutureBuilder 构建器位于主列内，该列也包装在一个容器中，并且该容器位于 SingleChiledScrollView 内。
它给出了这些错误
════════ Exception caught by rendering library ═════════════════════════════════
A RenderFlex overflowed by 25 pixels on the bottom.
The relevant error-causing widget was
Column
=> (its the flexible column inside the row with flexfit.tight)
Exception has occurred.
_AssertionError ('package:flutter/src/widgets/framework.dart': Failed assertion: line 5186 pos 16: 'child is! ParentDataElement<ParentData>': is not true.)
