react native flatlist with several arrays of data

I'M new to RN and need some help I have an object like

{title:"title",price:"price",subtitle:"subtitle"}

And I'd like to use 2 values at flatlist, like here -

<FlatList
        data={this.state.data}
        renderItem={({ item }) => (
          <ListItem
            title={`${item.name.first} ${item.name.last}`}
            subtitle={item.email}
         />
        )}

      />
    </List>

But in this example wasn't show structure of data so I'm confused what should I do. Please help me to solve it! At the end (render) I need a ListItem this view -

(title)  (price)

Or I should better use native-base, but the same questions about 2 value, passing to list item
