Shared element transitions

Modifier.sharedElement() and Modifier.sharedBounds() have been added to Compose. They allow you to create beautiful transitions between screens with finer control than the View system allowed. Wrap your AnimatedContent composables in SharedTransitionLayout and then add the Modifier.sharedElement() or Modifier.sharedBounds() onto the content that you’d like to share between screens. Compose will then find composables with matching keys and smoothly transition between them.

CameraX Compose

We are releasing a new Compose-specific CameraX artifact called camera-viewfinder-compose. In this first alpha release, you can use the new Viewfinder composable to display a camera preview on your screen that always shows the correct aspect ratio and rotation, whether you resize your window, unfold your device, or change the display or orientation. It also correctly handles camera and surface lifecycles, something that can be difficult when dealing with cameras. It also enables complex interactions in the camera coordinate system, making it easy for you to implement gestures such as tap-to-focus or pinch-to-zoom.
