为什么 firebase auth 在我的新三星手机上不起作用？

Question

我是 flutter 的初学者。 我有一个问题 firebase 身份验证，可以在所有手机和模拟器上使用电子邮件，但在我的新三星手机上却没有。 这是错误信息

/FirebaseAuth( 2571): [FirebaseAuth:] Preparing to create service connection to fallback implementation
W/System  ( 2571): Ignoring header X-Firebase-Locale because its value was null.
2
I/System.out( 2571): (HTTPLog)-Static: isSBSettingEnabled false
D/InputMethodManager( 2571): HSIFW - flag : 0

这是用户注册或登录的身份验证屏幕。

感谢您的帮助

Answer 1

我找到了解决方案 我们需要在 ma case 中添加 .trim() 函数来擦除空格 https://github.com/FirebaseExtended/flutterfire/issues/1760

Answer 2

修剪从文本字段中获取的文本。

emailController.text.trim(), 
passwordController.text.trim()
