Bugfix/179 instance name used to find dep get it dep class

[n3wtron]

Created a dedicated class to manage the dependency (type + instanceName)

[n3wtron]

Please note that this change is not retro compatible.
dependsOn attribute now need a GetItDep class instead of a Type

[escamoteur]

Hmm, give me a day to ponder about that :-)

[n3wtron]

Hi @escamoteur, probably I've found a way to make it retro-compatible. Can you check it, please?

[escamoteur]

thanks a lot for this contribution, I added some comments

[escamoteur]

Why did you remove the init()?

[n3wtron]

Hi, is necessary for this example? if I understood properly the init method is to "simulate" an operation that takes time, but in this case, I don't think is needed.
Anyway, I can add it again if you want.

[escamoteur]

No, it is used because any asnycRegistration expects an async factory function which your solution is because is uses the async keyword, but there is no such thing as an async class constructor that's why it would be a bad example.
the init function to be used like that has to return this to be usable like that

[n3wtron]

I will fix it

In the readme we currently have:

Automatic using dependsOn

In case that this services have to be initialized in a certain order because they depend on that other services are already ready to be used you can use the dependsOn parameter of registerFactoryAsync. If you have a non async Singleton that depends on other Singletons, there is registerSingletonWithDependencies. In the following example, DbService depends on ConfigService, and AppModel depends on ConfigService and RestService

  getIt.registerSingletonAsync<ConfigService>(() async {
    final configService = ConfigService();
    await configService.init();
    return configService;
  });
  getIt.registerSingletonAsync<RestService>(() async => RestService().init());
  getIt.registerSingletonAsync<DbService>(createDbServiceAsync,
      dependsOn: [ConfigService]);
  getIt.registerSingletonWithDependencies<AppModel>(
      () => AppModelImplmentation(),
      dependsOn: [ConfigService, DbService, RestService]);

When using dependsOn you ensure that the registration waits with creating its singleton on the completion of the type defined in dependsOn.

could you add there how to use the new InitDependency ?

I don't know if you follow me on Twitter but I just tweeted some thoughts of new functionality for get_it:

What do you think?

[escamoteur]

Awesome, thanks a lot!!!

[n3wtron]

Thanks to you @escamoteur your job with this lib is awesome.

[escamoteur]

Have you tried the get_it_mixin?

[n3wtron]

No, I didn't.
I will take a look and try it.
thank you
