KeyframesWithSplineSpec

public class KeyframesWithSplineSpec<T>(public val config: KeyframesWithSplineSpecConfig<T>) :
    DurationBasedAnimationSpec<T>

KeyframesWithSplineSpec creates a keyframe based DurationBasedAnimationSpec using the Monotone cubic Hermite spline to interpolate between the values in config.

KeyframesWithSplineSpec may be used to animate any n-dimensional values, but you'll likely use it most to animate positional 2D values such as Offset. For example:

You may also provide a periodicBias value (between 0f and 1f) to make a periodic spline. Periodic splines adjust the initial and final velocity to be the same. This is useful to create smooth repeatable animations. Such as an infinite pulsating animation:

The periodicBias value (from 0.0 to 1.0) indicates how much of the original starting and final velocity are modified to achieve periodicity:

• 0f: Modifies only the starting velocity to match the final velocity
• 1f: Modifies only the final velocity to match the starting velocity
• 0.5f: Modifies both velocities equally, picking the average between the two

Secondary Constructors

public constructor(
    config: KeyframesWithSplineSpecConfig<T>,
    @FloatRange(0.0, 1.0) periodicBias: Float,
) : this(config) {
    this.periodicBias = periodicBias
}

Constructor that returns a periodic spline implementation.
