A package that implements the architectural mediator pattern, with CQRS support.
(This package has nothing to do with owls, except that it was made by one).

Features

• CQRS (command/query request separation) support.

Getting started

• Install the package in your preferred way.
• Implement some commands and queries.
• Register them with the mediator.

Usage

A simple example of how to use the mediator class.

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

  // Register the query handler for its query type.
  // This will hopefully be code-generated later on.
  mediator.registerQuery(GetAsStringQueryHandler());

  // Create and run your query.
  String result1 = await mediator.runQuery(GetAsStringQuery(123));
  print(result1);

  // If you implemented the optional extension method, then you can do this instead.
  String result2 = await mediator.getAsString(123);
  print(result2);
}
