avoids caching a single multiplication operation. converts all toRadians and other helpers to use vector_math constant. (part of reducing dependency on latlong2).

Some files import '_64', some don't? Is that intentional?

As far as I can see we had vector_math as a dependency but it was not used anywhere?
This PR introduces the use of it for the degrees2Radians constant. Are there additional use cases in the future? If not I'd prefer to remove the dependency entirely and add the const to flutter_map directly.

Long terms I think it should be used from a future latlong package but not the current implementation of latlong2.

I would agree with @josxha here - adding a dependency just for this seems a little bit too much.

vector_math is a core flutter dependency, and we already use it in camera.dart for the matrix transform at line 301, we just don't explicitly depend on it. Matrix4 is exposed by package:flutter/material.dart

LGTM! I suppose that we indirectly depend on it anyway, so no harm in depending on it directly as well.

Would be great if you could resolve the conflicts as well :D.

np! also, we could consider using the aabb2 and other methods from vector_math in the future for things like bounding boxes and transforms!

Yep, that would make sense.
