GeoRawTransform class
Raw transforms are point transformation functions that are used to implement custom projections.
They typically passed to GeoProjection or GeoProjectionMutator. They are exposed here to facilitate the derivation of related projections. Raw transforms take spherical coordinates [lambda, phi] in radians (not degrees!) and return a point [x, y], typically in the unit square centered around the origin.

num> Function(List<num> )?) -
The inverse of forward.

forward
→ List<
num> Function(List<num> ) -
Transforms the specified point [lambda, phi] in radians, returning a
new point [x, y] in unspecified and implementation-dependent
coordinates.
