Flutter Apple Pay Integration

I’m ready to add Apple Pay to my existing Flutter application so users can complete a single, in-app purchase with one tap. The codebase is already live in the App Store TestFlight; what’s missing is the Apple Pay flow (one-time payment only, no subscriptions).

You’ll connect the Apple Pay sheet to my current checkout screen, pass the purchase token back to my backend, and make sure everything clears in Sandbox and Production. I’ll supply all merchant IDs, certificates, and a test build; you wire up the Flutter side, handle any required native iOS bits, and document the key steps so I can maintain the feature later.

I’m only considering freelancers who have successfully shipped Apple Pay in Flutter before—please point me to a live app or repo that proves it. If you can deliver a working demo build within a few days, let’s talk.
