Compose Animation
UI › Compose UI
Picking the right Compose animation API, from animate*AsState to Animatable.
Compose animation is a favourite interview area because it tests whether you can match an API to a problem instead of reaching for one tool for everything. Interviewers probe the difference between declarative state-driven helpers and the imperative Animatable, what AnimatedVisibility does by default, and how to drive animations from gestures. Expect questions on return types, coroutine usage, and animation specs like spring versus tween.
What this covers
- Choosing high-level declarative APIs (animate*AsState, AnimatedVisibility, Crossfade) vs low-level Animatable
- What animate*AsState returns and how it reacts to state changes
- AnimatedVisibility default enter/exit and customising with EnterTransition/ExitTransition
- Coordinating several values together with updateTransition / rememberTransition
- Animatable for imperative and gesture-driven motion using snapTo and animateTo in coroutines
- Animation specs (tween, spring, keyframes, snap, infiniteRepeatable) and rememberInfiniteTransition / animateContentSize
