Summary

Public functions
`ScalingParams`	`defaultScalingParams( edgeScale: Float, edgeAlpha: Float, minElementHeight: Float, maxElementHeight: Float, minTransitionArea: Float, maxTransitionArea: Float, scaleInterpolator: Easing, viewportVerticalOffsetResolver: (Constraints) -> Int )` Scaling params are used to determine when items start to be scaled down and alpha applied, and how much.
`FlingBehavior`	`@Composable flingBehavior(state: PickerState, decay: DecayAnimationSpec<Float>)` Create and remember a `FlingBehavior` that will represent natural fling curve with snap to central item as the fling decays.
`ScalingParams`	`scalingParams( edgeScale: Float, edgeAlpha: Float, minElementHeight: Float, maxElementHeight: Float, minTransitionArea: Float, maxTransitionArea: Float, scaleInterpolator: Easing, viewportVerticalOffsetResolver: (Constraints) -> Int )` This function is deprecated. This overload is provided for backwards compatibility with Compose for Wear OS 1.1 and was deprecated.

Public properties
`Float`	`DefaultGradientRatio` Default Picker gradient ratio - the proportion of the Picker height allocated to each of the of the top and bottom gradients.

flingBehavior

Added in 1.0.0

@Composable
fun flingBehavior(
    state: PickerState,
