Implementing Twitter’s App Loading Animation in React Native · React Native

by TM

The author of this blog post discusses how to recreate Twitter’s loading animation in React Native. The animation involves scaling the Twitter logo to reveal the app underneath. The author initially made the incorrect assumption that the logo became transparent, but later realized that the logo serves as a mask for the app and a white layer. The author provides a CodePen example to demonstrate the different layers involved in the animation. They then explain how to use the MaskedViewIOS component in React Native to mask the app and white layers with the Twitter logo.

To animate the loading animation, the author utilizes React Native’s Animated API. They explain that Animated.timing and Animated.spring are the main methods for defining animations. They use Animated.timing with a single Animated.Value to animate multiple components simultaneously. The author also provides a table with the estimated values for each component at different stages of the animation. They mention that the animation can be customized for different logo sizes and devices.
