Use case

Future<ProductDetailsResponse> queryProductDetails( Set<String> identifiers )
Query product details for the given set of IDs.
This function requires the app to know the product identifiers.

the older library flutter_inapp_purchases included a function getAvailableProducts(). This function returns all the products listed in the store.
Without this functionality, every time a new product is added in the store, the application must be updated to correspond.

Proposal

add a function getAvailableProducts()

This function should return a list of products that are listed in the App Store/ Play Store.
This way the changes to the product set can be made in the store without doing an app release.
