颤动忽略标头X-Firebase-Locale，因为它的值为null

Question

我将我的应用与 firebase 相关联，但是当我尝试在应用中注册新用户时，我收到了以下错误： 忽略标头 X-Firebase-Locale，因为它的值为 null。 那是验证屏幕代码：

class Authscreen extends StatefulWidget {
  @override
  Authscreenstate createState() => Authscreenstate();
}

final auth = FirebaseAuth.instance;

class Authscreenstate extends State<Authscreen> {
  void submitauthform(String email, String password, String username,
      bool islogin, BuildContext ctx) async {
    UserCredential authres;
    try {
      if (islogin == true) {
        authres = await auth.signInWithEmailAndPassword(
            email: email, password: password);
      } else {
        authres = await auth.createUserWithEmailAndPassword(
            email: email, password: password);
      }
    } on FirebaseAuthException catch (e) {
      String message = "error";
      if (e.code == 'weak-password') {
        message = 'The password provided is too weak.';
      } else if (e.code == 'email-already-in-use') {
        message = 'The account already exists for that email.';
      } else if (e.code == 'user-not-found') {
        message = 'No user found for this email.';
      } else if (e.code == 'wrong-password') {
        message = 'Wrong user privded for that user';
      }
      ScaffoldMessenger.of(context).showSnackBar(
        SnackBar(
          content: Text(message),
          backgroundColor: Theme.of(ctx).errorColor,
        ),
      );
    } catch (e) {
      print(e);
    }
  }

  @override
  Widget build(BuildContext context) {
    return Scaffold(
      backgroundColor: Theme.of(context).accentColor,
      body: Authform(submitauthform),
    );
  }
}

确保在Firebase Auth dashboard 上启用电子邮件/密码身份验证作为登录提供程序
