Interface
Common
```kotlin
interface PullToRefreshState
```
The state of a `PullToRefreshBox` which tracks the distance that the container and indicator have
been pulled.
Each instance of `PullToRefreshBox` should have its own `PullToRefreshState`.
`PullToRefreshState` can be used with other progress indicators like so:
## Properties
Common
```kotlin
@get:FloatRange(from = 0.0) val distanceFraction: Float
```
Distance percentage towards the refresh threshold. 0.0 indicates no distance, 1.0 indicates
being at the threshold offset, > 1.0 indicates overshoot beyond the provided threshold.
Common
```kotlin
val isAnimating: Boolean
```
whether the state is currently animating the indicator to the threshold offset, or back to
the hidden offset
## Functions
animateToThreshold
```kotlin
suspend fun animateToThreshold()
```
Animate the distance towards the anchor or threshold position, where the indicator will be
shown when refreshing.
animateToHidden
```kotlin
suspend fun animateToHidden()
```
Animate the distance towards the position where the indicator will be hidden when idle
snapTo
```kotlin
suspend fun snapTo(@FloatRange(from = 0.0) targetValue: Float)
```
Snap the indicator to the desired threshold fraction
