I know that Cesium uses Tween.js under the hood for animations. And Tween definitely provides callbacks for chaining animations together. Is there any way to get a callback from a camera.flyTo() command, for instance?
Unfortunately, Cesium’s Tween is not exposed. I posted some thoughts about it here:

Feel free to chime in there! I’d also like to see Cesium add support for accessing these callbacks.
