Answer 1

If you want to save the entire item object, AddToWishList should pass back the id from where it's being called.

import { AsyncStorage } from 'react-native';

AddToWishList = async (id) => {
  let itemToSave = JSON.Stringify(...dataArrayOfItems.filter(item => item.id === id))
  try {
   await AsyncStorage.setItem(id: itemToSave) 
    }
   catch (error) {
        //error saving data
    }
}
