Inbetween point of a line not quite accurate on low zooms. about flutter_map_line_editor

[josxha]

I just came across the package geodesy that might have this functionality:

LatLng midpoint = geodesy.midPointBetweenTwoGeoPoints(l1, l2);

It i inactive since a long time but it has a MIT license so the functionality could be copied over.

Thanks, I don't think the problem is the mid point of the latlng, but the fact we want the screen position of the midpoint of the line in screen coordinates (I may be wrong), so I think what we probably want to do is get the screen coords of both points, then calculate a simple halfway of those, and convert that back to latlng. There may be a simpler way, but I "think" that makes sense (I think flutter_map can do latlngtoscreenpos)
