MultiRegistrar class
Register multiple Objects so they can be retrieved with Registrar.get
MultiRegistrar only uses Location.registry and does not add widget to the widget try per Location.tree.
The lifecycle of each Object is bound to this widget. Each object is registered when this widget is added to the widget tree and unregistered when removed. If an Object is of type ChangeNotifier then its ChangeNotifier.dispose when it is unregistered.
usage: MultiRegistrar( delegates: RegistrarDelegate<MyService>(builder: () => MyService()), RegistrarDelegate<MyOtherService>(builder: () => MyOtherService()), , child: MyWidget(), );
