Bearing between two points

[lukepighetti]

Is calculating the bearing between two points within scope of this library?

Is it implemented?

If not, is there a known algorithm that will accurately calculate the bearing between two points?

Use case: I'm standing at point A, what compass bearing should I use to walk in a straight line to reach point B?

I think he is searching for something like geolocator's bearingBetween method, to get the compass bearing of two lat/lng points. Here is a reference link to geolocator's solution:

You could somewhat describe it as compass direction, but that's not really the correct wording here. :D
