Question

我可以使用我的 flutter 应用程序的网络版本进行 Google 登录，但无法通过 Android 应用程序进行 Google 登录。这是我得到的错误：

 GraphicExtModuleLoader::CreateGraphicExtInstance false

参考 StackOverflow 上的这个 Flutter and google_sign_in plugin: PlatformException(sign_in_failed, com.google.android.gms.common.api.ApiException: 10: , null) 答案，我不明白这个答案想说什么...... 但是，我确实在 firebase 上提供了我的 SHA1 密钥。重新下载并替换了我的 flutter 应用中的 google-services.json，但仍然无法在 Android 上登录。这是我的 GoogleSignIn 代码：

onPressed: () async {

                              await Firebase.initializeApp();

                              final FirebaseAuth _firebaseAuth =
                                  FirebaseAuth.instance;
                              final GoogleSignIn _googleSignIn =
                              GoogleSignIn();

                              Future<User> _signIn(BuildContext context) async {
                                debugPrint("1");
                                final GoogleSignInAccount googleUser =
                                await _googleSignIn.signIn();
                                debugPrint("2");
                                final GoogleSignInAuthentication googleAuth =
                                await googleUser.authentication;
                                debugPrint("a");
                                final AuthCredential credential =
                                GoogleAuthProvider.credential(
                                    idToken: googleAuth.idToken,
                                    accessToken: googleAuth.accessToken);

                                User userDetails = (await _firebaseAuth
                                    .signInWithCredential(credential))
                                    .user;
                                ProviderDetails providerInfo =
                                ProviderDetails(userDetails.uid);

                                List<ProviderDetails> providerData =
                                <ProviderDetails>[];
                                providerData.add(providerInfo);

                                UserDetails details = UserDetails(

                                if (details.userName.toString() != '') {
                                  debugPrint("Email ${details.userEmail}");

                                  globals.isLoggedIn = true;
                                  SharedPref prefs = SharedPref();
                                  String photoUrl = details.photoUrl.toString();
                                  prefs.save("photoUrl", photoUrl);

                                  prefs.save("username",
                                      details.userName.toString());

                                    builder: (context) => Dashboard()),
                              );
                            }

实际上我需要将此行添加到我的应用程序级 build.gradle 文件依赖项部分。

 implementation 'com.google.android.gms:play-services-auth:19.0.0'

也需要从此链接链接我的项目。
