I’m following the Magic Weather App, all working fine but I want to update customer’s record to indicate that they subscribed. According to the quick guide I need to have the following code but the sample code missing this bit of code. My question is how is working? Does Purchases.getCustomerInfo() does the actual purchase? Please advise.

try {
  CustomerInfo customerInfo = await Purchases.purchasePackage(package);
  var isPro = customerInfo.entitlements.allt"my_entitlement_identifier"].isActive;
  if (isPro) {
    // Unlock that great "pro" content
  }
} on PlatformException catch (e) {
  var errorCode = PurchasesErrorHelper.getErrorCode(e);
  if (errorCode != PurchasesErrorCode.purchaseCancelledError) {
    showError(e);             
  }
}

This is the code from the sample.
 

  void perfomMagic() async {
    setState(() {
      _isLoading = true;
    });

    CustomerInfo customerInfo = await Purchases.getCustomerInfo();

    if (customerInfo.entitlements.allnentitlementID] != null &&
        customerInfo.entitlements.allnentitlementID]?.isActive == true) {

      setState(() {
        _isLoading = false;
      });
    } else {
      late Offerings offerings;
      try {
        offerings = await Purchases.getOfferings();
      } on PlatformException catch (e) {
        await showDialog(
            context: context,
            builder: (BuildContext context) => ShowDialogToDismiss(
                title: "Error", content: e.message!, buttonText: 'OK'));
      }

      setState(() {
        _isLoading = false;
      });

      if (offerings.current == null) {
        // offerings are empty, show a message to your user
      } else {
        // current offering is available, show paywall
        await showModalBottomSheet(
          useRootNavigator: true,
          isDismissible: true,
          isScrollControlled: true,
          backgroundColor: Colors.black87,
          shape: const RoundedRectangleBorder(
            borderRadius: BorderRadius.vertical(top: Radius.circular(25.0)),
          ),
          context: context,
          builder: (BuildContext context) {
            return StatefulBuilder(
                builder: (BuildContext context, StateSetter setModalState) {
              return Paywall(
                offering: offerings.current!,
              );
            });
          },
        );
      }
    }
  }
