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
• MotionLayout DSL Syntax

New in Compose 1.1.0-alpha04

ConstraintLayout

• Allow referencing helpers when creating barriers

MotionLayout

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

MotionCarousel

• Carousel API for Compose using MotionLayout
  • See MotionCarousel.kt

Flow Helper

• Added API for ConstraintSet DSL
  • See createFlow
• Added API for ConstraintSet JSON
  • See FlowDemo.kt

Known Issues

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

New in Compose 1.1.0-alpha02

MotionLayout

• Refactor out MotionLayout.kt classes 616

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
