firebase - 登录时出现一些错误 PlatformException(ERROR_ADMIN_RESTRICTED_OPERATION, 此操作仅限管理员使用。, null)

Question

我是firebase的新手，我试图通过使用firebase的匿名身份验证来验证用户，但它给出了以下错误。

示例代码在这里：

验证飞镖文件。

class AuthServices {
  final FirebaseAuth _auth = FirebaseAuth.instance;

  //sign in method.
  Future signningAnon() async {
    try {
      AuthResult result = await _auth.signInAnonymously();
      FirebaseUser user = result.user;
      return user;
    } catch (e) {
      print("There is some error while singing $e");
      return null;
    }
  }
}

主文件：

void main() {
  AuthServices _auth = AuthServices();
  runApp(MaterialApp(
    title: 'chekcing firbase authentication',
    home: Scaffold(
      backgroundColor: Colors.blueAccent,
        appBar: AppBar(
          title: Text("Firbase authentication"),
        ),
        body: Center(
          child: RaisedButton(
            color: Colors.white,
            child: Text('click me'),
            onPressed: () async{
              print("object");
              dynamic result = await _auth.signningAnon();
              print('result is $result');
            },
          ),
        )),
  ));
}

这是 yaml 依赖文件。

dependencies:
  flutter:
    sdk: flutter

如果，有人有解决方案，请帮助。

您需要在控制台的 Firebase 身份验证部分添加匿名登录选项。您在哪里设置了项目。
