googleSignIn.signIn() 函数永远不会完成

Question

背景 所以我正在编写一个应用程序，使用谷歌的 gmail api 来读取经过身份验证的用户的电子邮件。

问题 谷歌身份验证流程一切正常，我可以给予同意，除了谷歌登录功能之外的所有功能仍在后台运行，并且在热重新启动应用程序时，我收到如下错误

E/MethodChannel#plugins.flutter.io/google_sign_in_android(28186): java.lang.IllegalStateException: Concurrent operations detected: signIn, signInSilently

只有当我再次重建应用程序时，我才能看到用户已登录。

初步分析 我认为密钥或 SHA 证书的配置有问题，但我已经多次交叉检查了所有内容。 相同的代码可以在完全不同的应用程序中正常工作。

使用的套餐 谷歌登录：^6.1.0 googleapis_auth：^1.1.0 Extension_google_sign_in_as_googleapis_auth：^2.0.9

代码

final GoogleSignIn googleSignIn = GoogleSignIn(
  serverClientId: "YOUR_ID_GOES_HERE",
  scopes: <String>[
    'email',
    'https://www.googleapis.com/auth/gmail.readonly',
  ],
);

Future<void> main() {
  WidgetsFlutterBinding.ensureInitialized();
  runApp(MyApp());
}

class MyApp extends StatefulWidget {
  const MyApp({Key? key}) : super(key: key);

  @override
  State<StatefulWidget> createState() => _MyAppState();
}

class _MyAppState extends State<MyApp> {
  GoogleSignInAccount? _currentUser;
  @override
  void initState() {
    super.initState();
    googleSignIn.onCurrentUserChanged.listen((GoogleSignInAccount? account) {
      setState(() {
        _currentUser = account;
      });
      if (_currentUser != null) {
        _handleGetEmails();
      }
    });
    silentlySignIn();
  }

  void silentlySignIn() async {
   var resp = await _googleSignIn.signInSilently();
    if (resp != null) {
      print(resp.displayName);
    }
  }

  @override
  Widget build(BuildContext context) {
    return MaterialApp(
          debugShowCheckedModeBanner: false,
          home: Scaffold(
            body: Center(
              child: ElevatedButton(
                onPressed: () async {
                  try {
                    var resp = await googleSignIn.signIn();
                    print(resp); // this part is never executed
                  } catch (error) {
                    print(error);
                  }
                },
                child: const Text("Authorize"),
              ),            
            ),
          ),
        );
  }
}
