I'm making In App Purchase to my app with in_app_purchase: ^0.3.5+1.
With android, I got detailed error message like BillingResponse.userCanceled, BillingResponse.itemAlreadyOwned.
With those Message, I can handle errors by case with proper actions.
But in IOS, I'm confused how to know User cancel the purchase.
When I cancel purchase in IOS, It's just say SKErrorDomain.
How can I specify When user cancel purchase in IOS?
