In my flutterflow.io project, I have created an application for my cafe, I have created 2 firestore collections, one is for menu items and second is for cart items. On home page I have created backend query on menu items and created button to add item in cart collections, One item is added, I want to increment and decrement item quantity in cart collection from home page, Now I want to display the quantity of item in cart collection on home page, but I am facing issue because I can create only one backend query, and I have already created menu item collection backend query. now please suggest the best way how can I display item quantity from cart collection on home page?
