BridgingCreator not initialized Crash in Superwall SDK During Paywall Display

[deogw]

I am encountering a BridgingCreator not initialized crash when attempting to display a paywall using the Superwall SDK in my Flutter application. The integration is successful, and users can navigate the app, but some users experience crashes when the paywall is displayed.

Crash analytics show that over 70% of these crashes occur when the device is in the background, possibly indicating an issue with background processes or initialization. However, I have not been able to reproduce this error during testing.

Below is the detailed error log:

Environment :

Flutter Version: 3.22.2
superwallkit_flutter: ^1.2.0
purchases_flutter: ^7.0.1

Initialization Code

Below is the code snippet I am using to initialize Superwall:

Future<void> initSuperWall(BuildContext context) async {
    try {
        final purchaseController = RCPurchaseController();
        final logging = Logging();
        logging.level = LogLevel.debug;
        logging.scopes = {LogScope.all};

        final options = SuperwallOptions();

        Superwall.configure(AppConst.superwallApiKey,
            purchaseController: purchaseController,
            options: options, completion: () {
                Log.logger.d('Executing Superwall configure completion block');
        });

        Superwall.shared.setDelegate(this);
        await purchaseController.configureAndSyncSubscriptionStatus(context);
    } catch (e) {
        Log.logger.e(e);
    }
}

Additional Information

The RCPurchaseController implementation is based on the Superwall example, with a slight modification to the RevenueCat listener:

Purchases.addCustomerInfoUpdateListener((customerInfo) async {
    final purchaseApi = sl<PurchaseApi>();
    bool hasActiveEntitlementOrSubscription = customerInfo.hasActiveEntitlementOrSubscription();
    if (hasActiveEntitlementOrSubscription) {
        Superwall.shared.setSubscriptionStatus(SubscriptionStatus.active);
    } else {
        Superwall.shared.setSubscriptionStatus(SubscriptionStatus.inactive);
    }

    await purchaseApi.updatePurchaseStatus(customerInfo, context);
});

Also, here is the code related to presenting the paywall:

Future doPurchase(BuildContext context) async {
    try {
        final handler = PaywallPresentationHandler();
        final popUpProvider = sl<PopupProvider>();
        final promoManager = PromotionPrefs();
        handler
            ..onPresent((paywallInfo) async {})
            ..onDismiss((paywallInfo) async {})
            ..onError((error) {
                Log.logger.d('Handler (onError): $error');
                AppHelper.reportError(
                    error,
                    StackTrace.current,
                    reason: 'Superwall Error',
                );
            })
            ..onSkip(handleSkipReason);

        Superwall.shared.registerEvent(popUpProvider.activePromoName ?? 'regular',
            handler: handler, feature: () async {
                if (isPro) {
                    promoManager.setClosing().then((_) {
                        context.pushNamed(Routes.proStatus, extra: true);
                    });
                }
            });

        Log.logger.d('Register method called successfully.');
    } catch (e) {
        Log.logger.d('Failed to call register method: $e');
    }
}

Hi @deogw !

Thanks for the report and sorry for the issues - we've released an update (1.2.1) that should mitigate these crashes. If you continue seeing them after updating, please feel free to reopen the issue and let us know!

[jaceknijaki]

This is not fixed in v1.2.1 (that uses Android sdk v1.2.3), we can still observe 2 crashes:

100% repro for us:

1. Move app to the BG while paywall is visible,
2. Try to get back to the app
3. Crash

[jaceknijaki]

Above problem seems to be caused by using singleInstance launchMode. Using signleTop or singleTask works fine.

[ianrumac]

Seems like that was the missing piece of the puzzle to reproduce this issue, after setting it to singleInstance can reproduce it consistently - thanks for the find @jaceknijaki , I'll update our docs to explicitly mention that.

[jaceknijaki]

We are not able to reproduce this issue on our side any more (after switching to singleTop), but unfortunately this crash can still be seen in Google Play crash reports.

We can also see java.lang.RuntimeException caused by:

Caused by kotlin.UninitializedPropertyAccessException: lateinit property instance has not been initialized

  at android.app.Instrumentation.callActivityOnCreate (Instrumentation.java:1384)
  at android.app.ActivityThread.performLaunchActivity (ActivityThread.java:3750)

Currently Superwall produces ~50% of all crashes we can see on Google Play, which is serious...
