What's New in 1.1 (Compose)

ConstraintLayout-compose 1.1 focuses on bringing more MotionLayout features in Compose.

Constraints can be created either via a Kotlin DSL (in modifiers or as a separate ConstraintSet), or via a JSON ConstraintSet.

Various examples can be found in this project.

• See the syntax for OnSwipe

New in Compose 1.1.0-alpha04

ConstraintLayout

• Allow referencing helpers when creating barriers
• Added API for Flow helper. See createFlow

MotionLayout

• Added a DSL for MotionScene. See MotionSceneScope
• Added a DSL for Transition. See TransitionScope
• Support to force remeasure on every frame with MotionLayoutFlag.FullMeasure

MotionCarousel

• Carousel API for Compose using MotionLayout

Known Issues

• Content may not remeasure properly if it doesn’t recompose together with the ConstraintLayout/MotionLayout parent.

New in Compose 1.1.0-alpha01

MotionLayout

• Limited support for onSwipe, drive the animation with swipes/dragging
• Added rememberMotionLayoutState. When passed to a MotionLayout Composable, it may be used to animate the internal progress value and observe changes to it (within a Composable scope) made by onSwipe
• Support for stagger, easing and quantized movements
• Updated internals to better handle recomposition
• Fixed MotionLayout laying out different when using a debugging flag
• Minor performance improvements

Known Issues

• When using onSwipe all drag events are consumed (i.e: onSwipe won’t work well with LazyList)
• MotionLayout #526: Possible crashes when using compose 1.1.X
