```kotlin
public class FloatTweenSpec(
    public val duration: Int = DefaultDurationMillis,
    public val delay: Int = 0,
    private val easing: Easing = FastOutSlowInEasing,
) : FloatAnimationSpec
```


`FloatTweenSpec` animates a Float value from any start value to any end value using a provided
`easing` function. The animation will finish within the `duration` time. Unless a `delay` is
specified, the animation will start right away.

#### Parameters

| | |
| --- | --- |
| duration | the amount of time (in milliseconds) the animation will take to finish. Defaults to `DefaultDurationMillis` |
| delay | the amount of time the animation will wait before it starts running. Defaults to 0. |
| easing | the easing function that will be used to interoplate between the start and end value of the animation. Defaults to `FastOutSlowInEasing`. |
