Implements and reviews in-app purchases and subscriptions across Flutter, Android, iOS, React Native and Kotlin Multiplatform. Use for product catalogs, purchase and restore flows, pending or interrupted purchases, server-side verification, acknowledgement, account binding, plan changes and store sandbox tests. Store submission belongs to mobile-release; account deletion to mobile-privacy.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Mobile Billing Trace each purchase from the product query to the entitlement your backend records. Reuse the [project brief](../../docs/agent-context.md), then inspect the billing client setup, the purchase listener, the backend verification endpoint and every screen that reads entitlement before changing a flow. The store-side lifecycle (subscription states, server notifications, acknowledgement deadlines, sandbox tools) is in the [billing lifecycle reference](../mobile-release/references/billing.md); this skill applies it to the app's code. ## Pick the reference | Project | Read | |---|---| | Flutter | [references/flutter.md](references/flutter.md) | | Android | [references/android.md](references/android.md) | | iOS | [references/ios.md](references/ios.md) | | React Native / Expo | [references/react-native.md](references/react-native.md) | | Kotlin Multiplatform | [references/kotlin-multiplatform.md](references/kotlin-multiplatform.md) | Flutter and React Native apps also need the Android and iOS references for store configuration and native behavior. Confirm the billing library version from the lock file; client APIs change across major versions. …

How to install
mdr add wrsilva/reis-mobile/mobile-billing@sha256:e28d85317c34bdb3The line at the top of this page pins the label git:20261023.8e142b7, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
