If you open the App.js file, you’ll see that the BigCard component relies on the current value of the state for three of its props.

From in-app chat to realtime graphs and location tracking, you can rely on Pusher to scale to million of users and trillions of messages. react-animations. Here, we’re getting the negative equivalent of the screen’s height and adding 20: But why? In this case, we want the animated value (yTranslate) to be 0 at the beginning of the animation. Using the interpolate method is optional if all we need to animate is the component’s width, height, margin, or padding. The app will have a minimal functionality to keep the focus on animation.
