Release 6.8.0 graduates flutter_inapp_purchase into the full OpenIAP ecosystem. The plugin now shares the same native stacks, type system, and tooling used by Expo IAP and the Kotlin Multiplatform SDK, giving Flutter teams a predictable upgrade path and richer diagnostics across both stores.

Highlights​

  • Flutter In-App Purchase 6.8.0 graduates the project into the full OpenIAP ecosystem. The release ships with three dedicated native stacks:

    From 6.8.0 onward, Flutter In-App Purchase stays in lockstep with these modules: Apple v1.2.2, Google v1.2.6, and GQL v1.0.8. That shared version alignment gives Flutter apps stable native compatibility and a unified type system straight from the OpenIAP schema.

Tooling and workflow​

  • Type generation, Podspecs, and Gradle builds all consume openiap-versions.json so dependency bumps require one edit.

Important changes​

  • getProducts, getSubscriptions, and getPurchaseHistories are permanently removed. Use fetchProducts(ProductRequest(...)) and getAvailablePurchases([PurchaseOptions(...)]) instead.
  • Purchase request helpers require explicit product types; passing the old “all” value throws an error to prevent invalid store calls.
  • Transaction identifiers surfaced by the stores remain untouched. For new server-side validation, rely on the unified purchaseToken exposed on every purchase record.
  • Transaction identifiers: transactionId is reinstated as the primary store reference (orderId on Android, StoreKit transaction ID on iOS). Android’s generic id is no longer repurposed for orders; when Google Play omits an orderId (typical for consumables), transactionId becomes null and clients should rely on the unified purchaseToken (Android purchase token / iOS JWS). This value is the canonical receipt for server validation. See the related react-native-iap discussion.
