Paywall logic for non-consumables in flutterflow for RevenueCat

Hi there,

I am looking at creating a paywall logic where after the user has created for example 100 entries in my database (using Supabase), then they will need to purchase a one-off non-consumables in the in app purchase in both Google Store and iOS Store via RevenueCat.

Does anybody know how and where should I implement the paywall logic?

Thanks in advance
