Flutter+Firebase + RevenueCat
Stack IntegrationFlutter + Firebase + RevenueCat: Mobile Subscriptions
RevenueCat abstracts the complexity of App Store and Google Play subscription billing, while Firebase handles user auth and real-time data — together they cover the full mobile subscription stack.
Use Cases
- Cross-platform subscription billing via App Store and Google Play
- Entitlement checking to gate premium features in Flutter
- Subscription status synced to Firestore for backend access control
- Paywall A/B testing and subscription analytics via RevenueCat dashboard
Implementation
Initialize RevenueCat's Purchases SDK alongside Firebase in main(). Use Purchases.getCustomerInfo() to check entitlements before rendering premium content. Sync RevenueCat customer ID with Firebase Auth UID via RevenueCat's Firebase extension or a Cloud Function webhook — this lets your backend verify subscription status server-side. Never rely solely on client-side entitlement checks for server-side resource access.
