implement-in-app-purchase

What problem does it solve?

Implements In-App Purchase (consumable, non-consumable, or subscription) following the project architecture. Asks whether there is a backend server, then generates the complete implementation: InAppPurchaseService, Cubit, State, View, DI registration, and purchase verification flow (local storage via StorageService OR backend endpoint call). Use whenever adding purchases, subscriptions, paywall, or premium features to the app, integrating App Store or Google Play billing, verifying receipts, or restoring purchases. Activate even when the user says 'make the app paid', 'add a paywall', 'implement premium', 'add a subscription plan', 'unlock premium features', or 'monetize the app' without explicitly mentioning InAppPurchase, StoreKit, or Google Play Billing.

Core Features & Use Cases
