Compose: animations Core principle Pick the smallest API that expresses the motion and its lifecycle. Procedure Identify the job: show or hide a subtree, animate one value, coordinate values from one state, resize content, swap content, or handle user-driven motion. Choose the matching API from the table. Prefer target-state APIs; use Animatable only when gestures, interruption, or imperative control require it. Check lifecycle: an alpha animation keeps content composed; AnimatedVisibility removes it after exit. Do not use a fade when unmounting is required. For AnimatedContent , render from the content lambda target and choose a contentKey only when visual identity differs from payload equality. Read AnimatedContent identity for state-holder details. Keep animated State in layout or draw block modifiers when it changes at frame rate; route deeper diagnosis to Compose performance . Use Navigation Compose transitions for destination swaps it owns, and dedicated libraries for art-based motion. Finish when the API, lifecycle, and content identity match the UI, no simpler API fits, and the relevant behavior is verified. API choice Need Prefer Show/hide a subtree with enter/exit semantics AnimatedVisibility One value follows state animate*AsState Several values follow one boolean, enum, or sealed state rememberTransition plus child animations Child size changes Modifier.animateContentSize() Different composable trees fill one region AnimatedContent , or Crossfade for the simple case Drag, fling, interruption, or imperative control Animatable Use an AnimationSpec when the default motion is wrong and a distinct label when multiple animations need tooling visibility. val width by animateDpAsState( targetValue = if (expanded) 200. dp else 56. dp, animationSpec = spring(dampingRatio = 0.7f ), label = \"fabWidth\" , ) For values that must remain synchronized, define them on one transition rather than several independent animate*AsState calls: val transition = rememberTransition(targetState = phase, label = \"phase\" ) val alpha by transition.animateFloat(label = \"alpha\" ) { target -> if (target == Phase.Visible) 1f else 0f } val offset by transition.animateDp(label = \"offset\" ) { target -> if (target == Phase.Visible) 0. dp else 24. dp } For animated fills, prefer drawBehind { drawRect(color.value) } over a value-form background when the color updates every frame. For an API ambiguity, start with the official Choose an animation API guide; use rememberInfiniteTransition for repeating cycles and SeekableTransitionState for seekable or test-controlled progress. When not to use this skill For side-effect timing or click-launched work, use Compose state and effects . For deep state-read or recomposition diagnosis, use Compose performance .",
