Mediator class

An implementation for the architectural mediator pattern, with CQRS support.

void main() async {
  // Create a new mediator, this should only be needed once per your application.
  Mediator mediator = Mediator();

  // Register the command handler for its command type.
  // This will hopefully be code-generated later on.
  mediator.registerCommand(GetAsStringCommandHandler());

  // Create and run your command.
  String result = await mediator.runCommand(GetAsStringCommand(123));
  print(result);
}
