Jetpack Compose internals

This book explores the guts of Jetpack Compose, the brand new library by Google and the Android team that will become the future of Android UI. Dedicating time now to learn about its internals in-depth will yield powerful skills to write modern and efficient Android apps in the future.

If you are interested in other use cases of Jetpack Compose rather than Android, this book has got you covered also. Jetpack Compose internals is very focused on exploring the compiler and runtime from a generic perspective, making the overall experience very agnostic of the target platform. The book also provides a chapter dedicated to diverse use cases for Jetpack Compose, which exposes a few really interesting examples over code.
