Projection class

Collection of Spherical Mercator projection methods.

Constructors

Projection({BinaryMessenger? binaryMessenger})

Constructor for Projection. The binaryMessenger named argument is available for dependency injection. If it is left null, the default BinaryMessenger will be used which routes to the host platform.

Properties
