🛰️ Compose Radar Report - Apr 22, 2026

Here is what Google released this week for Compose:

Foundation Compose

Added

• Introduced FlexBox and added ExperimentalFlexBoxApi.
• Added GridTrackSize MinMax support for safer flexible-grid usage.

Changed

• Migrated FlexBox DSL configuration to function-based style.
• Updated text editing internals (TextStyleBuffer / interval tree) for more robust range handling.

Fixed

• Fixed BasicTextField crashes and edge cases around concurrent text/selection updates and context-menu behavior.
• Fixed FlexBox layout issues including main-axis gap math, shrink handling, pixel distribution, and single-line cross-axis alignment behavior.
• Fixed grid-related sizing/overflow issues, including flexible-track aspect-ratio explosions and implicit-track gap calculation.

UI Compose

Added

• Added ComposeViewContext to support composing without attaching the view.

Changed

• Changed media-query APIs toward a more generic model and continued API-review follow-ups around adaptive behavior.
• Removed legacy UI feature flags around pointer navigation, focus dispatch, and autofill debugging callbacks.

Fixed

• Fixed popup bounding behavior when clipping is disabled.
• Fixed focus restoration edge cases and frame-rate request log spam.

Runtime Compose

Added

• Added SnapshotFlowManager manager-based flow support and expanded host-default CompositionLocal capabilities.
• Added keyed SideEffect API support.

Changed

• Continued rollout of the LinkTable runtime architecture and associated tracing/locking improvements.

Fixed

• Fixed LinkTable write/index/disposal issues and nested derived-state invalidation bugs.
• Fixed cancellation reporting and stability issues around snapshot-flow internals.

Material Compose

Added

• Added expressive chip overloads for FilterChip and InputChip.
• Added Material3ExpressiveApi annotation paths for clearer expressive API surfacing.

Changed

• Promoted expressive theme and wavy progress APIs (including CircularWavyProgressIndicator).
• Graduated inset focus-ring APIs and refined related component behavior.

Fixed

• Fixed focus-trapping behavior in DatePicker accessibility flows.
• Fixed inset focus-ring rendering regressions across switch/search/slider related paths.
• Fixed TimePicker sample behavior to prevent invalid time entry.

Animation Compose

Added

• Added visual-debugging API support for lookahead/shared-element animation workflows.

Changed

• Continued optimization work for shared-transition renderer state handling.

Fixed

• Fixed animation DSL and transition-state edge cases from the 1.11 cycle.

Compose Remote

Added

• Added combinedClickable, RemoteMutableFloatArray, and RemoteFontFamily support in the remote stack.
• Added richer flow-layout/document APIs and demos in the 1.0.0-alpha09 cycle.

Changed

• Changed clickable, onTouchDown, and onTouchUp to single-action-oriented signatures.
• Changed padding semantics from left/right toward start/end for directional correctness.

Fixed

• Fixed MatrixExpression.write behavior and several rendering/repaint crash paths.

That's all for this week.
