unproject method

Future<Map<String?, Object?>> unproject(
  1. MercatorCoordinate coordinate,
  2. double zoomScale
)

Calculate a coordinate for a given point on the map in Mercator Projection.

@param coordinate Point on the map in Mercator projection. @param zoomScale The current zoom factor applied on the map, is used to calculate the world size as tileSize * zoomScale (i.e., 512 * 2 ^ Zoom level) where tileSize is the width of a tile in pixels.

@return Returns a coordinate.
