🛰️ Compose Radar Report - May 20, 2026

Here is what Google released this week for Compose:

Compose Foundation

Added

• Added SelectionState and rememberSelectionState, giving SelectionContainer a state object for observing selected text and performing selection actions programmatically.
• Added TextFieldTextStyles, a read-only style query API for TextFieldState.

Fixed

• Fixed BasicTextField selection while editing text during a gesture.
• Fixed FlexBox shrink behavior when items exceed container bounds or hit their minimum intrinsic sizes.

Compose UI

Added

• Added MeshGradientPainter and MeshGradientScope for painter-based mesh gradients.
• Added SoundEffectOnInteraction, SoundEffect, and LocalSoundEffect to control click sound effects in a composable subtree.

Compose Runtime

Fixed

• Fixed a rare movable-content exception caused by an internal runtime collection.
• Fixed a LinkTable issue that could cause invalid writes after disposing a composition.

Compose Animation

Added

• Added experimental deferred transition APIs, including DeferredTransition, DeferredTransitionState, and ExperimentalDeferredTransitionApi.
• Added DeferredAnimatedContent and DeferredAnimatedVisibility for manually controlling transformations before handing off to the normal animation, useful for predictive back style flows.

Material 3 Compose

Added

• Added Modifier.scrollbar and ScrollbarDefaults, a visual-only scrollbar for scrollable content.
• Added rememberBottomSheetState, which creates a SheetState from an explicit set of enabled bottom-sheet values.

Fixed

• Fixed drawer back-press handling so drawer offset state is updated from the settled value.
• Fixed DatePicker number formatting so it respects the picker locale instead of only the device default locale.

Compose Remote Creation

Added

• Added RemoteFontFamily support for mapping Compose font families into Remote Compose text.
• Added more RemoteModifier transform APIs, including alpha, rotate, and scale.

Wear Material 3 Compose

Added

• Added one-handed gesture indicator components, including OneHandedGestureIndicator, OneHandedGestureScrollIndicator, and page indicator variants.
• Added GestureIndicatorSize plus tint/background customization for one-handed gesture indicators.

Fixed

• Fixed one-handed gesture callbacks so newly added gesture handlers during invocation do not cause concurrent modification issues.
• Fixed one-handed gesture indicators so they mirror based on wrist orientation rather than layout direction.
• Fixed AppScaffold time text updates across recomposition.

XR Compose

Added

• Added transformingMovable and SpatialMoveEventType for spatial move interactions.

Changed

• Updated SpatialGltfModel APIs with resource loading support through SpatialGltfModelSource, a resume() animation API, and clearer loaded/loading status objects.

Fixed

• Fixed fillMaxSize behavior on subspaces.
• Fixed edge cases in rotateToLookAtUser for parallel vectors and zero-distance cases.

XR Glimmer

Added

• Added GlimmerLazyColumn, GlimmerLazyListState, and the corresponding lazy-list scope/layout-info APIs.
• Added VoiceInputIndicator and ContainedVoiceInputIndicator.

Changed

• Renamed the previous vertical list surface into the new Glimmer lazy-list naming, including GlimmerLazyListScope and GlimmerLazyColumnDefaults.

That's all for this week.
