Question

I'm applying the Provider pattern to manage the state of my application So I have a ListView of CartItem and when I dismiss the CartItem from it a ProviderNotFoundException occur the logic and the code seems fine to me and I don't know where the problem exactly belongs .

I tried to change the Dismissed widget with an IconButton near my CartItem widget and the same problem occur .
