BoxConstraintsTweenDescription class final

Description for a BoxConstraintsTween animation that animates between BoxConstraints values.

This class is used for animating constraint properties such as minimum and maximum width and height of widgets.

Example usage:

final boxConstraintsTween = BoxConstraintsTweenDescription(
  animatedPropKey: 'constraints',
  duration: Duration(milliseconds: 400),
  begin: BoxConstraints(minWidth: 100, minHeight: 50),
  end: BoxConstraints(minWidth: 200, minHeight: 100),
  curve: Curves.easeInOut,
  trigger: AnimationTrigger.onTap,
  method: AnimationMethod.forward,
  reverseOnRepeat: false,
);
