【问题描述】：
我有一个 Flutter 应用程序，我正在尝试允许用户登录他们的 Gmail，因为我希望能够列出他们的电子邮件。当我按下我的LoginButton 时，系统会提示我登录 Gmail，然后我输入我的凭据，但随后它会返回带有LoginButton 的屏幕，我遇到了错误：
Unhandled Exception: PlatformException(sign_in_failed, com.google.android.gms.common.api.ApiException: 10: , null)
我尝试过的：
- 将
google-services.json添加到/android/app 并将GoogleService-Info.plist添加到ios/Runner。 - 为 Firebase 身份验证启用 gmail。
- 将我的调试 SHA1 和 SHA256 添加到我的 Firebase 身份验证中。
- 填写 OAuth 同意书（我是在其他所有事情之后才这样做的。我不知道这是否会影响它。）
有什么想法吗？谢谢！
这是我的代码：
class AuthService {
final GoogleSignIn _googleSignIn = GoogleSignIn();
final FirebaseAuth _auth = FirebaseAuth.instance;
final Firestore _db = Firestore.instance;
Observable<FirebaseUser> user;
Observable<Map<String, dynamic>> profile;
PublishSubject loading = PublishSubject();
AuthService() {
user = Observable(_auth.onAuthStateChanged);
profile = user.switchMap((FirebaseUser u) {
if (u != null) {
return _db
.collection('users')
.document(u.uid)
.snapshots()
.map((snap) => snap.data);
} else {
return Observable.just({});
}
});
}
Future<FirebaseUser> googleSignIn() async {
loading.add(true);
GoogleSignInAccount googleUser = await _googleSignIn.signIn();
GoogleSignInAuthentication googleAuth = await googleUser.authentication;
final AuthCredential credential = GoogleAuthProvider.getCredential(
accessToken: googleAuth.accessToken,
idToken: googleAuth.idToken,
);
FirebaseUser user = (await _auth.signInWithCredential(credential)).user;
updateUserData(user);
print("signed in " + user.displayName);
loading.add(false);
return user;
}
void updateUserData(FirebaseUser user) async {
DocumentReference ref = _db.collection('user').document('user.uid');
return ref.setData({
'uid': user.uid,
'email': user.email,
'photoURL': user.photoUrl,
'displayName': user.displayName,
'lastSeen': DateTime.now()
}, merge: true);
}
void signOut() {
_auth.signOut();
}
}
final AuthService authService = AuthService();

【问题讨论】：
-
您能否在问题中指定您是否已下载
google-services.json并在./android/app/google-services.json 添加到您的android 项目中？ -
是的，我已将
google-services.json添加到/android/app 并将GoogleService-Info.plist添加到ios/Runner。 -
我也遇到了这个问题。过去一年我们一直在顺利使用 Google 登录，所以我知道配置很好。它在 GoogleSignIn.signIn() 中失败。我也可以在身份验证部分下的 firebase 中看到该帐户。
-
我也面临同样的问题。我也使用谷歌登录一年多了。你找到解决办法了吗？请帮忙
