I am using purchases_flutter and revenueCat to offer a subscription on my app.

How can I run a function immediately after the payment is made?

Thank you.

With RevenueCat, you can make any action you want after the purchase line. Below is an example of my checkout function

static Future<Package?> makePurchases(Package? package, ValueNotifier<bool> isWaiting) async {
        try {
          isWaiting.value = true;
          purchaserInfo = await Purchases.purchasePackage(package!);
          await Purchases.syncPurchases();
          if (purchaserInfo.entitlements.all["Pro"]!.isActive) {
            purchaserInfo = await Purchases.purchasePackage(package);
          }
    
          // here purchase is done
          // do something
    
          isWaiting.value = false;
        } on PlatformException catch (e) {
          var errorCode = PurchasesErrorHelper.getErrorCode(e);
          if (errorCode != PurchasesErrorCode.purchaseCancelledError) {}
    
          isWaiting.value = false;
        }
        isWaiting.value = false;
        return null;
      }
