How to create shopping cart structure
Database & APIs
I want to create a shopping cart variable in app state that is made of a list of custom data types, that contain a document reference (which leads to a document that contains data regarding the product) and an int named "amount", but I experience issues when trying to update the amount of a given product the shopping cart list. Which way do you recommend to do this correctly, so I can change the amount of a given product when I tap a plus button. :)
