How do i prevent a new alias from being created when a user restores their subscription?

I am using RevenueCat's Flutter SDK to manage user subscriptions in my app. For associating user content in my database, I rely on the initial anonymous user ID generated by RevenueCat since i do not want to have to setup user accounts.

There is an issue though when a user deletes the app and reinstalls it, or installs the app on a new device and restores their purchase, RevenueCat generates a new Alias instead of using the original anonymous id. This is a problem because there is a maximum limit of 50 aliases.

Is there a way to make it so when the user restores a purchase it uses the original Anonymous App User ID instead of creating a new one? Here is the relevant portion of my code:

class SubscriptionProvider with ChangeNotifier {



bool _hasActiveSubscription = false;
String _activeEntitlement = '';
String _anonymousId = 'unpaidUser';  // Default to 'unpaidUser'



bool get hasActiveSubscription => _hasActiveSubscription;
String get activeEntitlement => _activeEntitlement;
String get anonymousId => _anonymousId;



Future<void> initialize() async {
    print("Starting RevenueCat configuration...");
    await configureRevenueCat();
    print("RevenueCat configuration completed.");

    print("Checking subscription status...");
    await checkSubscriptionStatus();
    print("Subscription status checked.");
  }



 Future<void> configureRevenueCat() async {
    print('Configuring RevenueCat...');
    try {
      Purchases.setLogLevel(LogLevel.debug); // Use LogLevel.debug only during development

      if (Platform.isIOS || Platform.isMacOS) {
        var config = PurchasesConfiguration("");
        await Purchases.configure(config);
      } else if (Platform.isAndroid) {
        var config = PurchasesConfiguration("");
        await Purchases.configure(config);
      }

      // Fetch CustomerInfo after configuring the SDK
      CustomerInfo purchaserInfo = await Purchases.getCustomerInfo();
      String userId = purchaserInfo.originalAppUserId;

      // Log in to RevenueCat with the originalAppUserId
      await Purchases.logIn(userId);

      print('RevenueCat configured and logged in successfully.');
    } catch (e) {
      print('Error configuring RevenueCat: $e');
      // Optionally handle the error, e.g., retry or fallback
    }
  }



 Future<void> checkSubscriptionStatus() async {
    print('Checking subscription status...');
    try {
      CustomerInfo purchaserInfo = await Purchases.getCustomerInfo();
      print('PurchaserInfo fetched: $purchaserInfo');
      updateSubscriptionStatus(purchaserInfo);
    } catch (e) {
      print('Error fetching PurchaserInfo: $e');
      loadSubscriptionStatusFromSharedPreferences(); // Fallback to SharedPreferences if online check fails
    }
  }



 void updateSubscriptionStatus(CustomerInfo purchaserInfo) {
    print('Updating subscription status...');

    // Directly set the anonymous ID from the purchaserInfo
    _anonymousId = purchaserInfo.originalAppUserId;
    print('Anonymous ID set to: $_anonymousId');

    _hasActiveSubscription = purchaserInfo.entitlements.active.isNotEmpty;
    _activeEntitlement = purchaserInfo.entitlements.active.values
        .map((e) => e.identifier)
        .join(', ');

    print('Active subscription status: $_hasActiveSubscription');
    print('Active entitlements: $_activeEntitlement');

    notifyListeners(); // Notify listeners about all changes
    saveSubscriptionStatusToSharedPreferences();
  }




Future<bool> restorePurchases() async {
    print('Attempting to restore purchases...');
    try {
      CustomerInfo restoredCustomerInfo = await Purchases.restorePurchases();
      print('Purchases restored. Info: $restoredCustomerInfo');
      updateSubscriptionStatus(restoredCustomerInfo);
      return true;
    } catch (e) {
      print('Failed to restore purchases: $e');
      return false;
    }
  }
