In my parent component I call hook useRef: const flatListRef = useRef(null); and then I want to use this flatListRef in child component. I tried to do like in documentation but without success.

I'm trying to set ID to View in ScrollView, so then I can use ScrollViewReader to scroll to top position(first item).What I'm struggling is when I try to get the index of an array, I get the error Argument type 'XXX' expected to be an instance of a class or class-constrained type.

I just followed a video on YouTube to add the PayPal button for my member to pay an amount before starting filling the registration form.

I am using PayPal SDK. Here is my code:
