In-app Purchases

We have managed In-App purchases for iOS and Android with “in_app_purchase” library. This library enables us to manage In-App purchases smoothly for both Android and iOS.

Configuring IAPs For iOS on App Store Connect.​

To accept auto-renew subscriptions in ur app first, you have to log in to App Store Connect -> Agreements, Tax and Banking

Then accept all the Paid Apps Agreements and you will see something like this:

If the agreements have not been accepted you can’t see the option to create the AutoRenew subscription.

Create the subscriptions​

  • Within App Store Connect, click Apps, followed by the App you wish to add in-app purchases to.
  • You should find In-App Purchases at the left side of your page, amongst the tabs.
  • Under In-App Purchases, click Manage. Here, we can add subscriptions as well as a “billing grace period” feature that postpones ending a subscription until a certain period of time passes after a subscription expires.

Click the + icon next to your In-App Purchases subheading to add an IAP, and follow the two-step process of choosing its type, followed by its name and reference number:

Your Reference Name should be a readable and easily recognizable label for the subscription item, whereas the Product ID needs to be a unique identifier for the item.

If you host many apps, using the com.org.app.iapId may be a more manageable Product ID convention, ensuring that there are no overlapping values between apps.

From here you can jump into each of your purchase items and configure a range of metadata — here are some of the more interesting features you can configure:

  • Subscription pricing, with a toggle to automatically generate prices for every supported currency. This is extremely useful for displaying prices in-app.
  • Promotional offers and introductory offers to spur new customers. Specific start and end dates can be set (or even no end date for an ongoing promotion), as well as a specific payment type. Be sure to check out all the options available for your In-App Purchase item to further tailor your offer.

Later on, we will fetch the configured IAPs further down and use in our project.

Configuring IAPs for Android on Google Play Console​

  1. As described in the above screenshot, you need to upload an APK and set up a merchant account before creating an In-app product.
  2. If you’ve done it, you can create a managed product or subscribe products as shown in below screenshot

Flow Overview​

  • Using "in_app_purchase” library, we fetch subscription details with the previously configured subscription SKUs for different platforms.
  • We display on the screen, the localized price and title of the subscription detail.
  • The user selects a subscription plan and completes a purchase.
  • The Subscription plan is immediately active and auto-renewable.
  • To cancel a plan, The user will have to go to the phone App settings and log in to the services provider
  • Select subscriptions and find the list of subscriptions available.

Codebase​

All the code related to In-App purchases lives in lib/dating/ui/dating/upgradeAccount/upgrade_account.dart:

Let’s start off by adding every product ID to the array called _kProductIds, It should look similar to this:

Note: testing In App Purchases is not available for iOS simulators, You can test this on android emulator only.

UpgradeAccount.dart responsibilities:​

This is a component for display. Here, we have the UI for the subscription screen. It also starts a subscription purchase when we press the list tile in the UI. It manages the logic for checking and getting a available purchasable products
