FlutterFlow + RevenueCat Integration Guide
RevenueCat is the industry standard for managing in-app purchases and subscriptions in mobile apps. For FlutterFlow apps distributed through the App Store and Play Store, RevenueCat handles the complexity of StoreKit and Google Play Billing through a unified API, letting you focus on your app experience rather than platform-specific payment code.
Why FlutterFlow + RevenueCat?
Apple and Google require that digital goods sold through their app stores use native in-app purchases — not Stripe or other payment processors. RevenueCat sits on top of StoreKit (iOS) and Google Play Billing (Android) and provides a single, cross-platform API that works identically on both. It also handles receipt validation, subscription state tracking, paywalls, A/B testing, and analytics — all features that would take months to build from scratch.
Setting up the integration
Install the purchases_flutter package in FlutterFlow's custom packages. Create a RevenueCat account and add your app for both iOS and Android. Configure your products in App Store Connect and Google Play Console, then add the same product identifiers to RevenueCat offerings. In FlutterFlow, initialise RevenueCat with your API keys on app launch using a custom action. Use RevenueCat's getOfferings() and purchasePackage() methods in FlutterFlow custom actions to display and process purchases.
Subscription state management
RevenueCat's CustomerInfo object tells you exactly which entitlements a user has, whether their subscription is active, and when it expires. Call Purchases.getCustomerInfo() on app launch and after every purchase. Store the entitlement status in a FlutterFlow app state variable and use it to conditionally show premium content or features. RevenueCat webhooks can also sync subscription state to your backend (Firebase or Supabase) for server-side access checks.
Real-world use cases
FlutterFlow + RevenueCat powers subscription apps across categories: productivity tools with monthly/annual plans, fitness apps with premium workout plans, language learning apps, content apps with ad-free tiers, and utilities with one-time unlock purchases. App Studio recommends RevenueCat for any FlutterFlow app that will be distributed publicly through the app stores and needs subscription revenue.
Common pitfalls
Set up sandbox testing accounts in App Store Connect and Google Play before testing purchases in FlutterFlow's test mode. RevenueCat's dashboard shows a different view for sandbox vs production — don't confuse the two. Subscription products must be created and approved in App Store Connect and Google Play Console before RevenueCat can offer them — this review process can take days. Always test subscription restoration (a legal requirement for iOS apps) before submitting to the App Store.
