MirrorAnimation<T> class
Widget that creates and plays an animation endlessly from the start to the end, then reverse to the start, then again to the end and so on.
You need to specify a tween that describes your animation and builder function that is called each frame you are animating. This function has signature of AnimatedWidgetBuilder.
It's also useful to specify a duration (default is 1 second).
To improve the performance of your animation you should put all widgets that are not effected by the animation into the child property. You get that child widget passed into the builder function. See also AnimatedWidgetBuilder.
The curve parameter can be used to apply a non-linear animation to your tween.
You can optionally limit the framerate (fps) of the animation by setting the fps value.
If you work with multiple animation widgets that are conditionally rendered, you might want to set a key. Otherwise Flutter will recycled your "old animation" which results in strange behavior.
You can connect this widget to the closest AnimationDeveloperTools
by setting developerMode to true.
