🛰️ Compose Radar Report - Jun 18, 2026

Here is what Google released this week for Compose:

Compose Animation

Added

• Added permitTransformDuringDeferredTransition to shared-content configuration so deferred shared elements can optionally keep transforming with their parent container instead of freezing during the deferred phase.
• Added inactiveElementColor to LookaheadAnimationVisualDebugging, making shared-element and lookahead debugging overlays easier to read.

Changed

• Refactored Transition into a sealed class and tightened the DeferredTransition API surface and documentation.
• Removed the ExperimentalAnimatableApi opt-in from Animatable.

Compose Foundation

Added

• Added named areas for Grid layouts, so you can declare semantic areas with GridConfigurationScope.area() and place items into them with Modifier.gridItem(area).
• Added merge operators and factory helpers for FlexBoxConfig and FlexConfig, making it easier to compose and override layout configuration.

Changed

• Renamed TextObfuscationMode.Default to System, and changed RevealLastTyped to act as an explicit override that always reveals the most recently typed character.
• Updated getSpanStyles and getParagraphStyles to take a TextRange instead of separate start and end indices, while also relaxing bounds checks around style queries.

Compose UI

Added

• Added the experimental ComposeUiFlags.isTrackpadPinchReinterpretationEnabled flag to reinterpret trackpad pinch gestures as mouse events with scale factors.
• Added support for standard JUnit 4 retry rules in AndroidComposeTestRule, recreating the internal test environment between attempts.

Changed

• Optimized BasicText and BasicTextField so line-height handling is cheaper when softWrap = false.

Fixed

• Fixed vector drawable parsing so parent clip-path nodes are preserved even when they contain nested group elements.
• Reduced unnecessary recomposition by optimizing scroll-capture state propagation across subcompositions.

Compose Runtime

Added

• Added verbose tracing for DisposableEffect and SideEffect work in the runtime.

Fixed

• Fixed snapshot apply observers so they are still notified when state is created in one snapshot and changed in a concurrent snapshot before the first snapshot is applied.
• Fixed a potentially significant derivedStateOf() retention leak in composition when forward writes kept derived state instances alive until disposal.
• Fixed LinkComposer so invalidations raised during composition no longer cause composables to skip instead of recompose.
• Fixed the vararg overload of remember so recomposition with fewer trailing keys invalidates correctly instead of reusing the wrong cached value.

Material 3 Compose

Added

• Added TopAppBarDefaults.snapAnimationSpec, exposing the default snap animation spec as public API.

Changed

• Graduated the expressive FloatingToolbar APIs from experimental.
• Updated pinnedScrollBehavior and enterAlwaysScrollBehavior to accept a ScrollableState, which handles reversed layouts and pre-scrolled content more reliably, while deprecating the older overloads.
• Removed the deprecated transformOriginState from DropdownMenuPopupPositionProvider.

Fixed

• Fixed TimePicker AM/PM toggle contrast.

Compose Remote Creation

Added

• Added public captureRemoteDocument Flow APIs and a captureSingleRemoteDocument overload that accepts RemoteCreationDisplayInfo.
• Added public compare operators for RemoteInt.
• Added RemoteStringArray as the array-based replacement for the removed RemoteStringList.

Changed

• Renamed RemoteBitmap to RemoteImageBitmap and RemoteBitmapShader to RemoteImageBrush for more consistent image API naming.
• Renamed RemoteBoolean comparison operators from eq and ne to isEqualTo and isNotEqualTo.
• Propagated LocalInspectionMode into the Remote Compose capture phase.

Wear Remote Material 3

Added

• Added public captureRemoteDocument Flow APIs and a captureSingleRemoteDocument overload that accepts RemoteCreationDisplayInfo.

Changed

• Updated containerPainter to take RemoteImageBitmap.
• Renamed RemoteBitmap to RemoteImageBitmap and the existing ValueChange factory functions to lowercase valueChange.

XR Compose

Added

• Added resource-backed model loading through SpatialGltfModelSource.fromResource.
• Added resume() and playbackSpeed support to SpatialGltfModelAnimation.

Changed

• Replaced the old resize path by deprecating ResizePolicy and the older resizable modifier in favor of the new SubspaceModifier.resizable overload and SubspaceModifier.transformingResizable.
• Marked rotateToLookAtUser as experimental.
• Changed SpatialGltfModelStatus.Loaded and SpatialGltfModelStatus.Loading to objects and moved more model-loading behavior into SpatialGltfModelState.

That's all for this week.
