Cancelling a purchase and failing a purchase reach your Flutter code the same way, as a PlatformException. That is how a paywall ends up showing a red error to someone who simply changed their mind on the store sheet.
PurchasesErrorHelper.getErrorCode is what distinguishes them, and two outcomes are not enough. A single call to Purchases.purchase can end five ways: cancelled, pending, completed, failed and unresolved. Pending is the one that catches people out. A parent still has to approve the purchase, or a slow payment method has to settle, and RevenueCat grants no entitlement until the store confirms it.
Which means the paywall screen should not be what decides access. A pending purchase can complete after the paywall closes or after the app has been killed, and RevenueCat does not push that change to the device. Keep a CustomerInfo listener in an object that lives as long as the app, and have every paid feature read the entitlement from it rather than from whatever the purchase call returned.
