ElasticScaleBox class

ElasticScaleBox 是一个带有弹性缩放动画的容器组件， 可用于包裹任意子组件，使其在显示时呈现弹性缩放效果。

用法示例：

ElasticScaleBox(
  child: Container(
    width: 260,
    height: 260,
    decoration: const BoxDecoration(
      color: Colors.white,
      shape: BoxShape.circle,
    ),
  ),
)

返回结果： 返回一个 TweenAnimationBuilder<double> 包裹的 Transform.scale 组件， 在指定动画周期内，child 从缩放比例 0 逐渐增长到 1，并带有 Curves.elasticOut 弹性动效。
