React Native - Use a keyExtractor with FlatList

Question

I have been getting the:

\"VirtualizedList: missing keys for items, make sure to specify a key property on an item or provide a custom keyExtractor\"
         


        

Answer 1

Actually, in my case, FlatList data prop value was not an array type (it was empty object) so when I add keyExtractor={(item, index) => item.key} it made an error.

I hope it helps you.
