Hello!
We are integrating subscriptions in Flutter
Sir we have two subscriptions(PRO and ELITE) in a single group(AppStore). We have user login system. We give app user id. So the issue is that it is working well but we need the following:
1. User want to upgrade from PRO to ELITE within the app. mean changing subscription plans within the app. Please guide me how to do it.
Please share any related documentation where i can follow the steps to do upgrade/downgrade subscription from the app, yes not from setting.
is there any code to do this?
