    extern double GMSGeometryArea(https://developers.google.com/maps/documentation/ios-sdk/reference/objc/Classes/GMSPath.html *_Nonnull path)

Returns the area of a geodesic polygon defined by `path` on Earth.

The "inside" of the polygon is defined as not containing the South pole.

If `path` is not closed, it is implicitly treated as a closed path nevertheless and the result is
the same.

All coordinates of the path must be valid.

The polygon must be simple (not self-overlapping) and may be concave.

If any segment of the path is a pair of antipodal points, the result is undefined -- because two
antipodal points do not form a unique great circle segment on the sphere.
