computeAngleBetween static method
Returns the angle between two LatLngs, in radians. This is the same as the distance on the unit sphere.
Implementation
static double computeAngleBetween(Point<double> from, Point<double> to) =>
distanceRadians(toRadians(from.x), toRadians(from.y), toRadians(to.x),
toRadians(to.y));
