How do I implement in-app purchases in Flutter?

To implement in-app purchases in Flutter, try Adapty’s SDK as a replacement for flutter-iap. It supports both iOS and Android, and handles subscriptions out of the box, including analytics, receipt validation, and more. Need help? Check out our Flutter IAP tutorial with code examples.

What’s the difference between Adapty and flutter-iap?

Flutter-IAP gives you low-level access to store APIs, but you’ll need to build subscription logic, analytics, and A/B testing on your own. Adapty handles all that out of the box: one SDK for subscriptions, paywalls, and revenue tracking with no backend required.

Do I need to build my own backend to use Adapty?

No, you don’t. Adapty takes care of subscription management and server-side validation. You don’t have to manually handle getSubscriptions, requestSubscription or receipt checks like in flutter-iap.

Does Adapty support iOS and Android?

Yes, Adapty supports in app purchases in Flutter apps on both iOS and Android, whether you’re using the standard Flutter-IAP plugin or not.

Where can I find code examples and docs?

You can explore the Flutter IAP documentation with setup guides, Flutter in-app purchases examples, and detailed instructions for handling purchases, upgrades, and renewals.

“We’ve been working with Adapty since 2021 and I couldn’t be happier about it. We’ve tried other subscription management platforms in the past so I can compare. Adapty introduced numerous features over the years and constantly helped us grow. They have the best analytics on the market and all the integrations you can think of. If you looking to boost the revenue of your app, I definitely recommend Adapty.”

Chris Bick

“We’ve tested more than three hundred paywalls in the space of four months. Adapty allows testing basically any element of the paywall, and we took advantage of that. We’ve tested them all: products, title text, CTA buttons, images, videos etc. With Adapty’s A/B testing, we managed to double our monthly revenue. I wasn’t sure if one instrument could make such an impact, but I witnessed it myself.”
