Answer by Luis-Carlos for React FlatList renderItem

adding to what @Balasubramanian stated, the renderItem points to the current item and since you are using a List component as a wrapper then you can also use the 'ListItem' component inside the renderItem function to render the current item's data, like so:

renderItem={({ item, index }) => {
  return (
     <ListItem
        key={index}
        title={item.name}
        onPress={ () => this.assetSelected(item) }
      />
  );
}
