ServiceHost class

IoC container

Register a service:

ServiceHost().register(MyServiceImpl());

Receive a service:

final myService = ServiceHost().get<MyServiceImpl>();

After registering one or more services, initializeServices must be called before receiving one of the newly registered service instances.

Interfaces for services can be used to enable switching out Service implementations more easily.

Register a service with interface:

ServiceHost().register<MyService>(MyServiceImpl());

Receiving a service via interface class:

// returns the MyServiceImpl from above example
final myService = ServiceHost().get<MyService>();

Services and interfaces must implement or extend abstract class Service.
