How do I add subscriptions to a Flutter app with RevenueCat?

Create products in both stores, group them into a RevenueCat offering, install purchases_flutter, present a paywall that calls Purchases.purchasePackage(), and gate premium features on the entitlement returned by Purchases.getCustomerInfo().

Why it matters

Native in-app purchase is verbose and platform-specific. RevenueCat abstracts both stores, handles restore, and reports MRR — the standard for Flutter subscriptions in 2026.

How to do it

  1. Create products in the stores

    App Store Connect: In-App Purchases → Auto-Renewable Subscription. Play Console: Monetization → Subscriptions.

  2. Add them to RevenueCat

    Products in RevenueCat mirror store product IDs. Group them into offerings (e.g., "default"). Attach an entitlement (e.g., "pro").

  3. Install the SDK

    flutter pub add purchases_flutter then configure with your public SDK keys.

  4. Identify the user

    await Purchases.logIn(userId); where userId is your Supabase or Firebase auth uid.

  5. Present the paywall

    Fetch offerings, show the packages, call Purchases.purchasePackage(pkg).

  6. Gate features on entitlement

    final info = await Purchases.getCustomerInfo(); final pro = info.entitlements.all['pro']?.isActive == true;

Frequently asked

Do I need a backend?
Not strictly. RevenueCat validates receipts. If you want server-side entitlement (e.g., an API that checks pro status), use webhooks + your own subscriptions table.
How do I test purchases before shipping?
App Store: Sandbox tester accounts. Play: internal testing track + test license.
