StaggeredAnimationList class

A widget that animates its children with staggered delays.

Each child fades in and slides up in sequence, creating an elegant cascading effect. Commonly used for lists, menus, and modal content.

Example usage:

StaggeredAnimationList(
  children: [
    Text('First item'),
    Text('Second item'),
    Text('Third item'),
  ],
)
