 - [ ] Render `Item` with `name`, `model`, `crew`, `hyperdrive_rating` and `cost_in_credits` (_Notice on the documentation we use an implicit return_).
 - [ ] If you want to add an `Image` just use this api to generate random images `https://picsum.photos/seed/car/400/200`, you can change `car` with something else to generate a new image.
 
+**🔭 Hint:** use varialbe interpolation with `${}` to generate new seeds  for each image.

+```typescript
+<Image source={{uri: `https://picsum.photos/seed/${item.name}/400/200`}} />
