oAuth Flutter redirect re-opens app

Hi there , I updated flutter sdk and appwrite from 0.15 to latest

Needed to do some changes for flutter code for sure but I faced a new problem in auth , after the google auth , the auth happens and shows at my console sessions , so it works fine .. but when it re-direct to my flutter app again after oauth, the app re-opens again showing splash screen again .. I have a check in my app if user is logged in open home screen , if not show login screen by checking get.account() at main, But it opens login screen every time I open the app , so I don't know where is the problem , auth happens on console , but when app do get.account() it doesn't retrun any sessions ,

problems :- 1- the redirect after oauth re-open the app showing splash screen 2- if I closed the app and opened it again the get.account() can't hear the session that already happened and showed at my console sessions .

want refer to that code works fine for email and password login so no problem in code ..

and even oauth that had a problem worked well from 0.8 appwrite to 0.15

check if user logged In or not ,, to choose home at myapp later .. works fine for email password auth .

userSigned = await account.get();
        isLoggedIn = true;
        client.addHeader("serverId", userSigned.$id);
      } on AppwriteException {
        isLoggedIn = false;
      }
    }

    runApp(const MyApp());

oauth code

        Future<dynamic> oAuthAccount =
         account.createOAuth2Session(
            provider: OAuthProvider.google
        );
        Future.delayed(Duration(seconds: 1), () async {
          userSigned = await account.get();
          return oAuthAccount;
        });
