I've made flutter app with auto-renewable subscriptions. It works well on Android, but from Appstore i received this letter:
Someone just gives very laconic advise:
there are few solutions
- local via library
- local via calling verifyReceipt directly
- server side validation via the same verifyReceipt
But I have no idea how to realize this in flutter neither local nor server... (((
Maybe anyone flutter guru can send me step-by-step lesson or so to deal with this quest?
Actually a lot of dart pub libraries (such a local_auth, etc) have samples what code one need to write in native - swift or kotlin to achive a result, but not in_app_purchase alas. I really got stucked. Some double-trouble it is.
