Flutter 用户在Flatter和FacebookLoginStatus中以不同的Facebook用户身份登录。错误

我仔细检查代码。我找不到它

   final FirebaseAuth _auth = FirebaseAuth.instance;

FacebookLogin fb=FacebookLogin（）

未来fblogin（上下文）异步{ 试一试{ 最终结果=等待fb.登录（权限：[

在此处输入代码

FacebookPermission.publicProfile， FacebookPermission.email ]))

}

---

最终解决。一旦注销并登录，等待fb.logout（）；最终结果=等待fb.login（）

  print(result.accessToken);
  switch (result.status) {
    case FacebookLoginStatus.Success:
      print("Facebook Login Success");
      final FacebookAccessToken accessToken = result.accessToken;
      AuthCredential credential =
          FacebookAuthProvider.credential(accessToken.token);
      await _auth.signInWithCredential(credential).then((value) async {
        //
        save();

        // print('Facebook BY USER');
        if (value.additionalUserInfo.isNewUser) {
          Navigator.push(
              context,
              MaterialPageRoute(
                  builder: (context) => EditProfileScreen(
                        back: false,
                      )));
        } else {
          Navigator.push(context,
              MaterialPageRoute(builder: (context) => main.MainTabs()));
        }
      });

      break;

    case FacebookLoginStatus.Cancel:
      print("Facebook Login Cancel");
      break;
    case FacebookLoginStatus.Error:
      print(result.toString());
      break;
  }
} catch (err) {
  _auth.signOut();
  print(err.toString());
}
