Composing content for the first time has always been a synchronous, uninterruptible process. The performance of this model is not ideal for computationally expensive compositions, affecting lazy layouts and heavy screen transitions the most. In the next release of Compose runtime we are introducing pausable composition that addresses this problem. It enables finer control over initial composition, allowing for much more efficient scheduling. This talk provides a deep technical overview of the feature, discussing implementation details and capabilities it unlocks. You will learn why pausable composition is the hottest new feature in Jetpack Compose and how your apps can benefit from it.

Learn how to elevate your Jetpack Compose animations by building a smooth, gesture-driven transition from a card to a full-screen modal. In this talk, we’ll explore advanced techniques for creating seamless screen transitions, focusing on how to move an image from a compact card layout to a fully expanded modal while maintaining a fluid and responsive user experience. We’ll dive into the intricacies of layering views in Compose, ensuring the image and other UI elements transition smoothly between screens. You’ll see how to synchronize animations with user gestures, such as dragging the modal down to dismiss it, and how to handle edge cases for a natural feel. This example goes beyond the basics, showcasing how to combine Compose’s animation API, Modifier.graphicsLayer, and pointer input. By the end of this session, you’ll have a deep understanding of how to create advanced, gesture-aware animations in Jetpack Compose, along with practical code examples you can apply to your own projects. Perfect for developers looking to push the boundaries of Compose animations and deliver standout user experiences.
