Describe the bug

According to Crashlytics, 3% are affected by this issue, causing fatal crash. I encapsulated RevenueCat functionality under the class below and only using this two functions to display paywall built on RevenueCat.

  class PaywallLogic {
    static Future<Offerings> initRevenueCat(BuildContext context) async {
      await Purchases.setDebugLogsEnabled(true);
      late PurchasesConfiguration configuration;

    if (Platform.isAndroid) {
      configuration =
          PurchasesConfiguration(<<revenueCatApiKeyGoogle>>);
    } else if (Platform.isIOS) {
      configuration =
          PurchasesConfiguration(<<revenueCatApiKeyApple>>);
    }
    await Purchases.configure(configuration);
    User? user = FirebaseAuth.instance.currentUser;
    if (user != null) await Purchases.logIn(user.uid);
    Offerings offerings = await Purchases.getOfferings();
    return offerings;
  }

  static Future<void> displayPaywall(BuildContext context) async {
    if (await Purchases.isConfigured == false) {
      await initRevenueCat(context);
    }

    try {
      final FirebaseRemoteConfig remoteConfig =
          Provider.of<FlavorSettings>(context, listen: false).remoteConfig;
      final String sku = remoteConfig.getString('sku');

      Offerings offerings = await Purchases.getOfferings();
      if (offerings.getOffering(sku)!.availablePackages.isNotEmpty) {
        await RevenueCatUI.presentPaywall(
          displayCloseButton: true,
          offering: offerings.getOffering(sku)!,
        );
      }
    } on PlatformException catch (e, s) {
      (...)
      );

      print(e);
    } catch (e, s) {
      (...)
    }
  }
}

Additional context

On main screen init, I am calling (inside initState):

void initRevenueCat() async {
    if (displayPaymentScreen) {
      offering = await PaywallLogic.initRevenueCat(context);
      PaywallLogic.displayPaywall(context);
    }

    setState(() {
      showPaywall = true;
    });
  }

I always use PaywallLogic class to call RevenueCat. I tried to replace await Purchases.isConfigured == false with a custom boolean flag to track if RevenueCat has been already initiated or not, but it didn't help - I was thinking that I shouldn't use Purchases at all before configuration, however it also did not help.

The text was updated successfully, but these errors were encountered:

👀 We've just linked this issue to our internal tracker and notified the team. Thank you for reporting, we're checking this out!

mshmoustafa · 2024-06-04T16:47:46Z

Hi @mpastewski,
Looks like the stack trace is cut off, can you see where in your code the exception is being thrown? That might give us a clue as to how the Purchases singleton is being used before it's instantiated

Hi @mshmoustafa,

Thanks for the note. Unfortunately, I wasn't able to identify it... Please check the full exception message below:

Thank you! Let me ask a mobile engineer for input on this.

WesleyClarkRC · 2024-06-13T20:16:27Z

Hi @mpastewski, Yes, you are correct that you should not try to make any calls to Purchases until you have configured the SDK. A member of our engineering team took a look at the stack trace and did confirm that it is a result of attempting to display a paywall before calling configure. Are there any other places where you potentially use Paywalls prior to the configure?

mshmoustafa · 2024-06-21T17:31:32Z

Hey @mpastewski,
Since this issue hasn't had any updates recently I went ahead and closed it. But if you're still experiencing the issue, please feel free to reopen.

SanamGoodVibesOfficial · 2024-07-08T04:08:21Z

This issue still persists, We had checked the isConfigured status before executing any rc methods. Please fix !!

idish · 2024-09-09T07:34:53Z

I can confirm that the issue still persists, calling and awaiting on configure() won't solve the issue, that kind of crash still happen sometimes

nuzelac · 2024-09-13T15:35:40Z

I am experiencing the same. I call await Purchases.configure in main.dart and everything works fine in iOS or during testing in Android, but I see crashes in Android production related to "There is no singleton instance ..."

lukyanov · 2024-09-18T14:45:23Z

I am experiencing the same. I call await Purchases.configure in main.dart and everything works fine in iOS or during testing in Android, but I see crashes in Android production related to "There is no singleton instance ..."

Confirming exactly the same behaviour.

JoonasN · 2024-09-26T15:39:05Z

I can confirm that I'm also experiencing the same issue.

I am experiencing the same. I call await Purchases.configure in main.dart and everything works fine in iOS or during testing in Android, but I see crashes in Android production related to "There is no singleton instance ..."

I can also confirm this.

There is still a problem. Please open it

Thanks, everyone, for continuing to report this. We recently identified that this can happen on Android if:

the user backgrounds the app when PaywallActivity is open, and
enough time passes causing Android to decide to kill the app in the background, and then
the user resumes the app

This issue has been fixed in purchases-flutter 8.1.6. Can you please upgrade and let us know if this has been resolved?

If you continue to experience this issue after upgrading, please share breadcrumb logs and the launchMode as these will help our team dig further into this. Thanks.
