Flutter: When I used  the sdk RevenueCat version 6.23.0 it worked perfectly, I have updated to the latest 8.1.0 and it does not show me the paywall, it shows me error 23, maybe the methods are different, I share how I call it.

in the main.dart I initialize it and check if it is a subscriber.

Future<void> initRevenueCat(BuildContext context) async {
await Purchases.setDebugLogsEnabled(true);
PurchasesConfiguration configuration;
if (Platform.isAndroid) {
configuration = PurchasesConfiguration('goog_xxxxxxxx');
await Purchases.configure(configuration);
}
else if (Platform.isIOS) {
configuration = PurchasesConfiguration('appl_xxxxxxxx);
await Purchases.configure(configuration);
}
bool esPro = false;
try { CustomerInfo customerInfo = await Purchases.getCustomerInfo();
 List<String> entitlementIdentifiers = ="Monthly", "Annual", "Six Months"];
 for (String id in entitlementIdentifiers) { if (customerInfo.entitlements.allaid]?.isActive == true) { esPro = true;
 break;
 } else { esPro = false;
 } } final prefs = await SharedPreferences.getInstance();
 await prefs.setBool('isSubscribed', esPro);
 } on PlatformException catch (e) { String? errmsg = e.message;
 }
}

And to call the paywall I have always used this

Future<void> showPayWall(BuildContext context) async {
PaywallResult result = await RevenueCatUI.presentPaywall(displayCloseButton: true);
if (result.name == 'purchased') {
final prefs = await SharedPreferences.getInstance();
await prefs.setBool('isSubscribed', true);
Navigator.pushNamedAndRemoveUntil(context, 'home', (Route<dynamic> route) => false);
}
}

but it returns error23, with the RevenueCat sdk version 6.23 it didn't give me an error.

Can you help me?

Thanks.
