data class JellyFabConfig(val expandStagger: Long = 150, val collapseStagger: Long = 100, val secondaryExpandStagger: Long = 150, val secondaryCollapseStagger: Long = 80, val shadowOpacity: Float = 0.55f, val shadowBlurFactor: Float = 0.2f, val bounceFactor: Float = 0.18f, val secondaryLayerSpacingMultiplier: Float = 1.8f, val layerDistance: Dp = 80.dp)

Configuration for JellyFab animation feel, layout spacing, and motion physics.

Most of these values are "texture controls" — tweak them to make the FAB menu feel snappier, softer, slower, or more playful.

Constructors

JellyFabConfig

constructor(expandStagger: Long = 150, collapseStagger: Long = 100, secondaryExpandStagger: Long = 150, secondaryCollapseStagger: Long = 80, shadowOpacity: Float = 0.55f, shadowBlurFactor: Float = 0.2f, bounceFactor: Float = 0.18f, secondaryLayerSpacingMultiplier: Float = 1.8f, layerDistance: Dp = 80.dp)

Properties

bounceFactor

val bounceFactor: Float = 0.18f

How strongly the blob surface stretches at each bulge point. Increase for more “jelly wobble”.

collapseStagger

val collapseStagger: Long = 100

Delay between each primary-layer FAB collapsing inward (ms). Generally slightly smaller than expandStagger for a quicker close.

expandStagger

val expandStagger: Long = 150

Delay between each primary-layer FAB expanding outward (ms). Higher values = more sequential "bloom" animation.

layerDistance

val layerDistance: Dp

Base distance from the main FAB to the primary-layer FABs. Increase to spread items farther apart.

secondaryCollapseStagger

val secondaryCollapseStagger: Long = 80

Delay between each secondary FAB collapsing back inward (ms). Smaller values = quicker collapse motion.

secondaryExpandStagger

val secondaryExpandStagger: Long = 150

Delay between each secondary FAB expanding along the arc (ms).

secondaryLayerSpacingMultiplier

val secondaryLayerSpacingMultiplier: Float = 1.8f

Multiplier controlling how far secondary FABs extend outward relative to the primary layer distance.

shadowBlurFactor

val shadowBlurFactor: Float = 0.2f

Multiplier controlling how far the shadow softens/spreads when bulges animate.

shadowOpacity

val shadowOpacity: Float = 0.55f

Base opacity used when drawing the glowing soft shadow under the main FAB. Higher = darker shadow.
