RolledOutFoil class
An implicitly animated widget that handles position animations for foil effects.
This widget takes a gradient and animates its position based on the rollout values, which can come from pointer tracking and/or Roll animations. It works as a second animation layer after AnimatedFoil handles the gradient color animations.
This class is responsible for the smooth movement of the gradient as the user interacts with the widget or as Roll animations progress.
