@ExperimentalAnimationSpecApi
public class ArcAnimationSpec(
public val mode: ArcMode = ArcBelow,
public val durationMillis: Int = DefaultDurationMillis,
public val delayMillis: Int = 0,
public val easing: Easing = FastOutSlowInEasing, // Same default as tween()
) : DurationBasedAnimationSpec
```
`DurationBasedAnimationSpec` that interpolates 2-dimensional values using arcs of quarter of an
Ellipse.
To interpolate with `keyframes` use `KeyframesSpecConfig.using` with an `ArcMode`.
As such, it's recommended that `ArcAnimationSpec` is only used for positional values such as:
`Offset`, `IntOffset` or `androidx.compose.ui.unit.DpOffset`.
The orientation of the arc is indicated by the given `mode`.
Do note, that if the target value being animated only changes in one dimension, you'll only be
able to get a linear curve.
Similarly, one-dimensional values will always only interpolate on a linear curve.
#### Parameters
| | |
| --- | --- |
| mode | Orientation of the arc. |
| durationMillis | Duration of the animation. `DefaultDurationMillis` by default. |
| delayMillis | Time the animation waits before starting. 0 by default. |
| easing | `Easing` applied on the animation curve. `FastOutSlowInEasing` by default. |
