How to get all instances from DI as List<AbstractClass>

[slkmikhail]

HI!

Could you give advice how to get all instances from DI as List?

I have AbstractClass and more than one implementations (singleton).
I'd like to get all of them from DI as List without additional efforts.

I used a similar approach to #470 (comment). Not sure if it's the "right" way but it works for my use case.

@module
abstract class ThingOperationModule {
  @lazySingleton
  List<Thing> get things =>
      GetIt.instance.getAll<Thing>().toList(growable: false);
}

...

abstract class Thing {}

@Named("thingone")
@Injectable(as: Thing)
final class ThingOne extends Thing {}

@Named("thingtwo")
@Injectable(as: Thing)
final class ThingTwo extends Thing {}
