Background:
NSLocale is one of the property in the SKProduct and SKProductDiscount class in StoreKit. NSLocale itself does not have a simple way to be converted to a properly list map and thus cannot be passed back to Dart code directly. It seems to me that most of the properties in NSLocale are not particularly too useful to IAP and we could just expose the countrySymbol which seems matching the android IAP API.

• I would like to gather more use case information to see how many people do need the detailed NSLocale information thats only related to IOS.
