sag*_*mar 1 firebase firebase-authentication flutter
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 dart 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;
}
}
}

您需要在控制台的 Firebase 身份验证部分添加匿名登录选项。你在哪里设置你的项目。
