I am searching for a way to implement this and So far I have reached nowhere. The Exact thing that I meant by animating a polyline is an uber-like animation. Things I have thought of is building each coordinate of routes using a loop and a timer. But it rather seems to be expensive, another thought is just to plot a simple curved line using canvas from one point to another (also hypothetical). In Android, it is achieved by using overlays, and flutter only supports tile overlays.
