/**
 * Spring animation configuration.
 *
 * @param mass - The weight of the spring. Reducing this value makes the
 *   animation faster. Defaults to 4.
 * @param damping - How quickly a spring slows down. Higher damping means the
 *   spring will come to rest faster. Defaults to 120.
 * @param stiffness - How bouncy the spring is. Defaults to 900.
 * @param duration - Perceptual duration of the animation in milliseconds.
 *   Actual duration is 1.5 times higher. Defaults to 550ms if `dampingRatio` is
 *   provided.
 * @param dampingRatio - How damped the spring is. Value `1` means the spring is
 *   critically damped, value `<1` means the spring is underdamped and value
 *   `>1` means the spring is overdamped. Defaults to 1 if `duration` is
 *   provided.
 * @param velocity - Initial velocity applied to the spring equation. Defaults
 *   to 0.
 * @param overshootClamping - Whether a spring can bounce over the `toValue`.
 *   Defaults to false.
 * @param energyThreshold - Relative energy threshold below which the spring
 *   will snap to `toValue` without further oscillations. Defaults to 6e-9.
 * @param reduceMotion - Determines how the animation responds to the device's
 *   reduced motion accessibility setting. Default to `ReduceMotion.System` -
 *   {@link ReduceMotion}.
