如何解决Flutter崩溃iOS-NSInvalidArgumentException
有人知道这次崩溃是什么吗？我在网上查了一下，有些结果似乎相似，但不完全相同。这是Crashlytics中的痕迹：

这似乎与EditText有关（此崩溃发生在我的登录屏幕上），但我不知道是什么。仅影响一台设备-13.6.1上的XS Max。没有其他XS Max设备或13.6.1上的其他设备受到影响，仅此一个受到影响，可能是由于设备配置或其他原因造成的？任何想法都会有所帮助。
另一方面，是否有办法从Crashlytics获取更具可读性的日志？好像得到了Flutter在调试应用程序上抛出的确切错误？我没有使用Swift的经验，所以iOS的日志对我来说毫无意义。谢谢！
