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

Codebase
All the code related to In-App purchases lives in lib/ui/upgradeAccount/UpgradeAccount.dart :
Let’s start off by adding every product ID to the array called _kProductIds, It should look similar to this:
