RevenueCat Flutter plugin
This is not an official RevenueCat repo. We use this plugin at PostMuse and decided to open source it. We welcome contributions of any kind. This implementation uses the native Android and iOS RevenueCat libraries.
This library uses native RevenueCat libraries 1.x.x, which means it does not yet use iOS and Android version 2.x.x - We are planning to update the library, but we also welcome pull requests if you want to be helpful.
Plugin is published on Pub. Add this to your
dependencies: revenuecat: ^1.0.4
flutter packages get
Import it in your dart files
How to use
Initialize the plugin
await RevenueCat.setup("YOUR_API_KEY_HERE", null);
If you have user accounts, the second parameter should be the user id. Leaving that
null makes RevenueCat generate ids for you. Read more in the docs
- Know if the user is paying
This bit is async. You need to listen for changes to the Purchaser Info and find a way to update the app UI to reflect locked/unlocked features.
RevenueCat.addPurchaseListener(purchaseListener); RevenueCat.addPurchaserInfoUpdateListener(purchaserListener); RevenueCat.addRestoreTransactionListener(purchaserListener);
We recommend you do this at the highest level in your app and find a way to propagate this info. We use an InheritedWidget to keep this state and listen for changes in another "blocker" widget that updates when the InheritedWidget changes state. The "blocker" widget blocks access to whatever is below it and shows a "PRO" badge on top. This is approach is simplistic but effective, and works for us.
Bottom line is you need to listen for state changes from RevenueCat. Listener structure is found here.
- Get the Entitlements
var entitlements = await RevenueCat.getEntitlements();
Response is a Map with Entitlements, which then contain Offerings, which contain Products. Products contain price, period, introductory price, etc. It's best to look at the models directly to understand more.
- Display Products, start payment flow
- RevenueCat will take care of the rest and update your listeners from number 3
