# Animation

Animation class

Widgets can either incorporate these animations in their build functions directly by reading their current value and listening to their state changes or they can use the animations as the basis of more elaborate animations that they pass along to other widgets.

Most widgets that perform an animation receive an Animation object as a parameter, from which they read the current value of the animation and to which they listen for changes to that value.
