UI Animations with Lottie and After Effects

By: Mireia Alegre Ruiz, Emilio Rodriguez Martinez

Overview of this book

Lottie is a small and scalable JSON-based animation file. LottieFiles is the platform where Lottie animations can be uploaded, tested, and shared. By combining the LottieFiles plugin and the LottieFiles platform, you’ll be able to create stunning animations that are easy to integrate in any device. You’ll also see how to use the Bodymovin plugin in After Effects to export your animation to a JSON file. The book starts by giving you an overview of Lottie and LottieFiles. As you keep reading, you’ll understand the entire Lottie ecosystem and get hands-on with classic 2D animation principles. You’ll also get a step-by-step guided tour to ideate, sketch for storytelling, design an icon that will fulfill the needs and expectations of users based on UX, and finally animate it in Adobe After Effects. This will help you get familiar with the After Effects environment, work with vector shape layers, create and modify keyframes using layer properties, explore path and mask features, and adjust timing easily to create professional-looking animations. By the end of this animation book, you’ll be able to create and export your own Lottie animations using After Effects and implement them in mobile apps using React Native. You’ll also have an understanding of 2D animation best practices and principles that you can apply in your own projects.

Summary

In this chapter, we have learned about the way Lottie animations can be loaded into React Native, using basic integrations such as TypeScript types, and adding external assets into our animations. This gives us the ability to display complex animations inside our React Native apps, but what happens if we need to be in control of the playback (for example, tell the animation to start/stop based on events happening in the app)?

Let's move on to the next chapter to discover how controlling Lottie animations in lottie-react-native is done.
