```kotlin
public class VectorizedSpringSpec<V : AnimationVector>
private constructor(
    public val dampingRatio: Float,
    public val stiffness: Float,
    anims: Animations,
) : VectorizedFiniteAnimationSpec<V> by VectorizedFloatAnimationSpec(anims)
```


`VectorizedSpringSpec` uses spring animations to animate (each dimension of) `AnimationVector`s.


## Secondary Constructors

```kotlin
public constructor(
    dampingRatio: Float = Spring.DampingRatioNoBouncy,
    stiffness: Float = Spring.StiffnessMedium,
    visibilityThreshold: V? = null,
) : this(
    dampingRatio,
    stiffness,
    createSpringAnimations(visibilityThreshold, dampingRatio, stiffness),
)
```


Creates a `VectorizedSpringSpec` that uses the same spring constants (i.e. `dampingRatio` and
`stiffness` on all dimensions. The optional `visibilityThreshold` defines when the animation
should be considered to be visually close enough to target to stop. By default,
`Spring.DefaultDisplacementThreshold` is used on all dimensions of the `AnimationVector`.

#### Parameters

| | |
| --- | --- |
| dampingRatio | damping ratio of the spring. `Spring.DampingRatioNoBouncy` by default. |
| stiffness | stiffness of the spring. `Spring.StiffnessMedium` by default. |
| visibilityThreshold | specifies the visibility threshold for each dimension. |
