Dart mediator package #

Inspired by https://github.com/jbogard/MediatR

Example Usage #

Create a request

 class AddRequest extends IRequest<int> {
  final int i;

  AddRequest(this.i);
}

Create a request handler

class AddRequestHandler extends IRequestHandler<int, AddRequest> {
  @override
  Future<int> call(AddRequest request) async {
    return request.i + 1;
  }
}

Register the handler to the mediator instance

 final mediator = Mediator(Pipeline());

 mediator.registerHandler<int, AddRequest, AddRequestHandler>(
          () => AddRequestHandler(),
        );

Start sending requests!

final addedOrFailure =await mediator.send<int, AddRequest>(
         AddRequest(2),
       );
print(addedOrFailure.fold((left) {
// an instance of Failure
},
(right) {
// The added number
}));
