On fresh install, first authentication fails, but will succeed on the second app open.

Flutter v3.24.3
games_services: using develop branch

Seems to be working properly on the stable release.

Android or iOS?

[gnarhard]

I was experiencing it on iOS. Didn't check android.

I am unable to replicate the behavior on iOS. Can you share the code for your auth flow? Are you seeing an error, or are you just not seeing auth succeeding?

The problem was that GameAuth.isSignedIn was always returning null first from the player stream and then the true sign in value was being returned second. This would make my game assume there was no user signed into Game Center every time. No error, just unsuccessful auth. Auth flow looks like this and works perfectly on the stable release:

Future<void> signIn(
      BehaviorSubject<List<LoadingMessage>> loadProgressStream$) async {
    if (!_connectivityService.hasConnectivity) return;

    if (await Env.isEmulator) return;

    if (await isSignedIn) {
      debugPrint("Player already signed into Games Services");
      return;
    }

    try {
      await GameAuth.signIn();
    } catch (e, stackTrace) {
      debugPrint("Error signing into Games Services: ${e.toString()}");

      await ExceptionHandlerService.captureException(e, stackTrace: stackTrace);

      loadProgressStream$.add([
        ...loadProgressStream$.value,
        LoadingMessage(
          id: LoadingMessage.incrementId(loadProgressStream$),
          message: 'failed to sign into games services',
          status: LoadingStatus.error,
        )
      ]);
    }
  }

Thanks for the quick response. I will implement a similar flow and find the issue.

My pleasure! Thank you for all of your hard work on this package.

Please try the patch.

games_services:
    git:
      url: https://github.com/Abedalkareem/games_services.git
      ref: bugfix/back-compat
      path: games_services

"Because every version of games_services from git depends on games_services_platform_interface ^4.1.1 which doesn't match any versions, games_services from git is forbidden."

I tried using a dependency_override but games_services is not linking to the path of games_services_platform_interface, it's linking to a hosted version.

Sorry. Please pull again, if that doesn't work, please run flutter clean then pull.

[gnarhard]

That fixed it! On a fresh install, I'm now getting proper authentication. Thank you!
