[英]why firebase auth doesn't work on my new samsung phone?
我是 flutter 的初學者。我有一個問題 firebase auth email 在所有手機和模擬器上工作,但在我的新三星手機上它沒有。 這是錯誤信息
/FirebaseAuth( 2571): [FirebaseAuth:] Preparing to create service connection to fallback implementation
W/System ( 2571): Ignoring header X-Firebase-Locale because its value was null.

I/System.out( 2571): (HTTPLog)-Static: isSBSettingEnabled false
D/InputMethodManager( 2571): HSIFW - flag : 0
這是我的身份驗證屏幕,用戶可以在其中注冊或登錄。

謝謝您的幫助
我找到了我們在 ma case 中需要的解決方案,以 add.trim() 函數來擦除空格https://github.com/FirebaseExtended/flutterfire/issues/1760
修剪從文本字段中獲取的文本。
emailController.text.trim(),
passwordController.text.trim()
