我是 firebase 的新手,我正在尝试使用 firebase 的匿名身份验证来对用户进行身份验证,但它给出了以下错误。
示例代码在这里:
正在验证 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;
}
}
}
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
# The following adds the Cupertino Icons font to your application.
# Use with the CupertinoIcons class for iOS style icons.

toast: ^0.1.5

如果有人有解决方案,请帮忙。
您需要在控制台的 Firebase 身份验证部分添加匿名登录选项。您设置项目的位置。
我已启用匿名登录。仍然陷入错误。 我通过在settings.gradle中降级谷歌服务插件来解决问题
id("com.google.gms.google-services") version "4.4.1" apply false
到
id("com.google.gms.google-services") version "4.3.15" apply false
