Your Flutter app shouldn't know a product identifier exists. It only needs the word pro.

I re-read the docs before writing this. Hardcode the ID and a Black Friday price waits on App Store review. Name the entitlement instead and that tier ships from a dashboard, no build.

Nobody hits a line limit in FlutterFlow. They hit the parser.

Custom code gets rejected on what the Dart analyzer can resolve, not how much you've written. The export switch that settles the argument sits behind a $150/month tier.

One Dart codebase ships to six targets. Your revenue doesn't travel with it.

Apple and Google take 15-30% of a mobile subscription. Stripe on the web takes 2.9% plus $0.30. Same plan and the same customer, but you reconcile the money twice.
