PurchasesDart

PurchasesDart is a pure Dart implementation of the purchases_flutter plugin, designed to facilitate in-app purchases and subscriptions. The purchases_dart package follows closely the native APIs from purchases_flutter. You can use it with all platforms Flutter supports, not just iOS and Android. it is designed to work with different payment gateways (stores) and can be integrated with various store implementations.

Getting Started

Before using PurchasesDart, you must configure it with PurchasesDartConfiguration. This configuration requires an API key, a user ID, and a storeProduct instance. Below is an example of how to configure PurchasesDart:

await PurchasesDart.configure(
  PurchasesDartConfiguration(
    apiKey: env.revenueCatApiKey,
    appUserId: userId,
    storeProduct: StoreProductInterface,
  ),
);

It requires a storeProduct to communicate with the store backend. The storeProduct class serves as an interface for communication with different stores. For example, the StripeStoreProduct from purchases_dart_stripe extends the StoreProductInterface for communication with the Stripe store backend. Similarly, if you want to build for the Play Store, you would need to create a StoreProductInterface implementation specific to the Play Store.

Integration with Stripe

For integrating Stripe as the store backend, please refer to the purchases_dart_stripe implementation. This additional package provides a StripeStore implementation that can be used with PurchasesDart.

Important Notes

It is crucial to use a consistent appUserId with PurchasesDart. Using AnonymousUserId is not recommended because there is currently no way to restore the purchases of an anonymous user if the application is uninstalled.
