we have integrated In-app purchases in flutter using this "in_app_purchase: ^3.0.7" package everything is working fine. Still, our application is something anybody can use without login or Sign-up, so here we are facing the issue we need to store the purchase details in the DB but to do that we need to pass the Email ID from which account it has been purchased. Still, we cannot get a solution for this issue, so if there is any way to achieve this, please add your answers here.
Thanks in advance!!
