[in_app_purchase_storekit] Storekit2 RestorePurchase should give a single event. #187355
Description
Use case
Right now with storekit2, every restored purchase is an event in purchaseStream So if I have 2 purchases, I get two events.
This is unexpected and a problem for multiple reasons.
- It is different from storekit1 and android behaviour. On both android and storekit1 a restore would come in as a single event with multiple purchases.
- There is no way knowing when all purchases are restored. You could take a guess with some sort of timeout, but there is no way to know for sure.
- There is no way knowing there is nothing to be restored. When there is nothing to restore there is no event.
- It is inefficient. There is no way combining purchase restores and sending a single request to your backend due to points 2 and 3 above. Therefore, each restore is a call to your backend. Each call is probably something like: update purchase -> fetch all purchases for user -> calculate and store grants.
Proposal
RestorePurchase should give a single event with multiple purchases. Or an empty list in case there are no purchases to restore.
