```kotlin
public class SpringSpec<T>(
    public val dampingRatio: Float = Spring.DampingRatioNoBouncy,
    public val stiffness: Float = Spring.StiffnessMedium,
    public val visibilityThreshold: T? = null,
) : FiniteAnimationSpec<T>
```


Creates a `SpringSpec` that uses the given spring constants (i.e. `dampingRatio` and `stiffness`.
The optional `visibilityThreshold` defines when the animation should be considered to be visually
close enough to round off to its target.

#### 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 |
