AnimationSpec

Configure how animations behave over time.

AnimationSpec Types

Spec	Description
tween()	Duration-based with easing
spring()	Physics-based spring animation
keyframes()	Define values at specific times
snap()	Instant change, no animation
infiniteRepeatable()	Loops forever
repeatable()	Loops N times

Tween Animation

animateFloatAsState(
    targetValue = 1f,
    animationSpec = tween(
        durationMillis = 300,
        delayMillis = 50,
        easing = FastOutSlowInEasing
    )
)

Spring Animation

animateFloatAsState(
    targetValue = if (expanded) 1f else 0f,
    animationSpec = spring(
        dampingRatio = Spring.DampingRatioMediumBouncy,
        stiffness = Spring.StiffnessLow
    )
)

Spring Constants

DampingRatio	Description
DampingRatioHighBouncy	0.2 - Very bouncy
DampingRatioMediumBouncy	0.5 - Medium bounce
DampingRatioLowBouncy	0.75 - Low bounce
DampingRatioNoBouncy	1.0 - No bounce

Stiffness	Description
StiffnessHigh	Fast
StiffnessMedium	Medium
StiffnessMediumLow	Medium-slow
StiffnessLow	Slow
StiffnessVeryLow	Very slow
