this is my very first stackoverflow question :D
I am currently trying to build a shopping list app in Flutter. I use firebase as database.

Now I want to make the app so that if "Milk" is already on the shopping list, and then I want to add "Milk" again, the "Number" of milk is increased by one. Currently, "Milk" is then simply on the list twice.
The structure of the database is as follows: database
I am grateful for any tips. Cheers
