## Animations
Often you'd want to animate specific props in the Camera. For example, if you'd want to create a custom zoom gesture, you can smoothly animate the Camera's `zoom` property.
The following example uses [react-native-reanimated](https://github.com/software-mansion/react-native-reanimated) (v2) to animate the `zoom` property:
```tsx
import Reanimated, {
useAnimatedProps,
useSharedValue,
withSpring,
} from "react-native-reanimated";
const ReanimatedCamera = Reanimated.createAnimatedComponent(Camera);
Reanimated.addWhitelistedNativeProps({
zoom: true,
});
export const App = () => {
const zoom = useSharedValue(0);
const onRandomZoomPress = useCallback(() => {
zoom.value = withSpring(Math.random());
}, []);
const animatedProps = useAnimatedProps>(
() => ({ zoom: zoom.value }),
[zoom]
);
return (
<>
Zoom randomly!
)
}
```
### Implementation
1. The `Camera` is converted to a reanimated Camera using `Reanimated.createAnimatedComponent`
2. The `zoom` property is added to the whitelisted native props to make it animatable.
> Note that this might not be needed in the future, see: [reanimated#1409](https://github.com/software-mansion/react-native-reanimated/pull/1409)
3. Using [`useSharedValue`](https://docs.swmansion.com/react-native-reanimated/docs/api/useSharedValue), we're creating a shared value that holds the `zoom` property.
4. Using the [`useAnimatedProps`](https://docs.swmansion.com/react-native-reanimated/docs/api/useAnimatedProps) hook, we apply the shared value to the animated props.
5. We apply the animated props to the `ReanimatedCamera` component using the spread syntax.
