Android
```kotlin
public object PickerDefaults
```
Contains the default values used by [Picker](/jetpack-compose/androidx.wear.compose/compose-material/components/Picker)
## Functions
scalingParams
```kotlin
public fun scalingParams(
edgeScale: Float = 0.45f,
edgeAlpha: Float = 1.0f,
minElementHeight: Float = 0.0f,
maxElementHeight: Float = 0.0f,
minTransitionArea: Float = 0.45f,
maxTransitionArea: Float = 0.45f,
scaleInterpolator: Easing = CubicBezierEasing(0.25f, 0.00f, 0.75f, 1.00f),
viewportVerticalOffsetResolver: (Constraints) -> Int = { (it.maxHeight / 5f).toInt() },
): androidx.wear.compose.material.ScalingParams
```
Scaling params are used to determine when items start to be scaled down and alpha applied,
and how much. For details, see [ScalingParams](/jetpack-compose/androidx.wear.compose/compose-material/interfaces/ScalingParams)
defaultScalingParams
```kotlin
public fun defaultScalingParams(
edgeScale: Float = 0.45f,
edgeAlpha: Float = 1.0f,
minElementHeight: Float = 0.0f,
maxElementHeight: Float = 0.0f,
minTransitionArea: Float = 0.45f,
maxTransitionArea: Float = 0.45f,
scaleInterpolator: Easing = CubicBezierEasing(0.25f, 0.00f, 0.75f, 1.00f),
viewportVerticalOffsetResolver: (Constraints) -> Int = { (it.maxHeight / 5f).toInt() },
): ScalingParams
```

flingBehavior
```kotlin
@Composable
public fun flingBehavior(
state: PickerState,
decay: DecayAnimationSpec = exponentialDecay(),
): FlingBehavior
```
Create and remember a [FlingBehavior](/jetpack-compose/androidx.compose.foundation/foundation/interfaces/FlingBehavior) that will represent natural fling curve with snap to
central item as the fling decays.
