RenderFlex 在底部溢出了 14 个像素。相关的导致错误的小部件是 AlertDialog

Question

我正在创建一个对话框，当我单击编辑图标按钮时它会打开，但是当我单击文本字段输入文本时，它会向我发送此错误

SELECT SUBSTRING(col, 1, CHARINDEX('|', col) - 1)
FROM yourTable;

这是我的对话框代码

════════ Exception caught by rendering library ═════════════════════════════════
A RenderFlex overflowed by 14 pixels on the bottom.
The relevant error-causing widget was
AlertDialog

这是我的对话框的样子

当点击第一个文本框时，它看起来像这样

请帮我解决它。

您可以将scrollable的{​​{1}}参数设置为AlertDialog以避免溢出：

true
