SlideDown class

A widget that animates the sliding down of its child widget.

The SlideDown widget is used to create smooth sliding animations for its child widget. It animates the child widget's position from the top to its original position.

Example usage:

SlideDown(
  delay: 500, // Delay before animation starts in milliseconds (optional)
  speed: 0.5, // Animation speed (default is 0.50)
  animate: true, // Whether to animate (default is true)
  child: Text('Slide down animation'), // The child widget to be animated
)
