When you directly have access to the AnimationController this snippet will start/stop the animation, wherever it left off.

animationController.isAnimating
    ? animationController.stop()
    : animationController.forward();

Here the .isAnimating property is of type bool and is true when the animationController is animating at the moment. Depending on the result .stop()/.forward() will stop/start the animation respectively.
