Shaker class

A widget that applies a shake animation effect to its child.

The Shaker widget wraps a child widget and can trigger a shake animation when isShaking is true or via a ShakeController.

Example:

Shaker(
  isShaking: true,
  duration: Duration(milliseconds: 1000),
  child: Text('Shake me!'),
)

With controller:

final controller = ShakeController();
Shaker(
  controller: controller,
  child: Text('Shake me!'),
)
// Later:
controller.shake();
