Server-Side In-App Purchases in Dart
summary
Shows how to build a Dart REST server that verifies receipts via Android Publisher and the App Store Server API, stores order IDs, expiration times and subscription state in a database, and polls for updates rather than relying only on webhooks. Uses shelf_route for endpoints and the Google APIs plus App Store Server SDK packages. Implements Pub/Sub pulls to receive Google Play notifications, calls purchase endpoints to get full details, and notes hosting and async-trigger limits compared with Firebase functions.
