Flutter Channel stable, 2.0.1iOS 14.4TextFormField[LayoutConstraints] Unable to simultaneously satisfy constraints.
Probably at least one of the constraints in the following list is one you don't want.
Try this:
(1) look at each constraint and try to figure out which you don't expect;
(2) find the code that added the unwanted constraint or constraints and fix it.
(Note: If you're seeing NSAutoresizingMaskLayoutConstraints that you don't understand, refer to the documentation for the UIView property translatesAutoresizingMaskIntoConstraints)

Make a symbolic breakpoint at UIViewAlertForUnsatisfiableConstraints to catch this in the debugger.
The methods in the UIConstraintBasedLayoutDebugging category on UIView listed in <UIKitCore/UIView.h> may also be helpful.

文本字段上的 onTap 只是将焦点赋予该字段 - 键盘出现 - 但不会更改视图上的任何内容。
我读到，对于某些人来说，此消息可以忽略，但对于某些人来说，应用程序更新已被 Apple 取消。
我们如何解决这个限制问题？
在 Form() 小部件中使用 key 属性时似乎是一个错误。
GlobalKey<FormState>()也可能是您的容器/小部件与键盘发生冲突。如果 IOS 导致不稳定的行为，则会破坏屏幕对象的约束。
尝试移除集装箱（高度和宽度）限制。这对我有用。
这是一个 Flutter 和/或内部 Apple Bug（在我看来）......它似乎来自键盘上的自动更正选项。设置 auto Correct: false，在大多数情况下您将避免错误，但这并不完整。
如果您向后移动表单，点击上一个表单字段，它似乎仍然会触发。
