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.
