React Native Animation Transform

Objects in motion have momentum and rarely come to a stop immediately animations allow you to convey physically believable motion in your interface react native provides two complementary animation systems animated for granular and interactive control of specific values and layoutanimation for animated global layout transactions animated api

Spinvalue new animated value 0 first set up animation animated timing this spinvalue tovalue 1 duration 3000 easing easing linear easing is an additional import from react native usenativedriver true to make use of native driver for performance start next interpolate beginning and end values in this case 0 and

Transforms are style properties that will help you modify the appearance and position of your components using 2d or 3d transformations however once you apply transforms the layouts remain the same around the transformed component hence it might overlap with the nearby components you can apply margin to the transformed component the nearby components or padding to the container to prevent
