Thanks for making this plugin, it's really helpful since the nativescript-purchase plugin doesn't build on Android with the latest version of NativeScript! Question... I'm integrating this plugin for iOS in-app purchases, however the one thing I can't figure out how to do is to retrieve the receipt data for an iOS subscription. The nativescript-purchase plugin had a receiptData property on their transaction object, however InAppPurchaseTransactionState doesn't seem to have this.

Is there any code involved?

public initIosSubscriptions(user: UserView) {
        console.log('Initializing iOS subscriptions...');
        const productName = this.iosProductName(user);
        console.log(`Product name: ${productName}`);

        // Get iOS subscription product, based on number of units and discounts.
        this.inAppPurchaseManager.list([ productName ], InAppPurchaseType.Subscription)
            .then((result: InAppListProductsResult) => {
                if (!result.products?.length) {
                    console.warn(`Could not find iOS subscription product with name: ${productName}`);
                    alert('Purchasing a subscription is not available on this device! Please try our website.');
                    return;
                }
                this.iosProduct = result.products[0];
                // Found iOS subscription product, set up listener for when we purchase a product.
                console.log('Setting up listener for purchasing products...');
                const purchaseStateUpdateListener: InAppPurchaseStateUpdateListener = {
                    onUpdate: (purchaseTransactionState: InAppPurchaseTransactionState): void => {
                        // Item has been purchased, sync local items list ...
                        console.log('In transaction updated event! purchaseTransactionState: ', purchaseTransactionState);
                        const key = `${purchaseTransactionState.productIdentifier}-${purchaseTransactionState.resultCode}`;
                        if (!this.processedTransactionUpdates[key]) {
                            this.processedTransactionUpdates[key] = true;
                            if (purchaseTransactionState.resultCode === InAppPurchaseResultCode.Failed)
                                alert(`Purchase of ${purchaseTransactionState.productIdentifier} failed!`);
                            else if (purchaseTransactionState.transactionReceipt)
                                // Purchase succeeded, store receipt so we can check if the iOS subscription is active from a nightly job.
                                this.userService
                                    .updateIOSSettings({ input: { receiptData: purchaseTransactionState.transactionReceipt } })
                                    .subscribe(updatedUser => {
                                        this.authService.save(updatedUser);
                                        this.iosProductUpdated.emit(purchaseTransactionState.resultCode === InAppPurchaseResultCode.Purchased);
                                    });
                        }
                    },
                    onUpdateHistory: (purchaseTransactionState: InAppPurchaseTransactionState): void => {
                        if (purchaseTransactionState.resultCode === InAppPurchaseResultCode.Restored) {
                            // Item has been  restored, sync local items list ...
                        }
                    }
                };
                InAppPurchaseManager.bootStrapInstance(purchaseStateUpdateListener).then(inAppPurchaseManager => {
                    this.inAppPurchaseManager = inAppPurchaseManager
                });
            })
    }
