dependsOn confusion

[Reprevise]

I'm a bit confused on the dependsOn syntax. Before I was using readyFuture and that worked fine but I decided to try the new beta version. Here's how I register my singletons.

  getIt.registerSingletonAsync<AndroidDetails>(
    (_) => AndroidDetailsImplementation()..init(),
  );
  getIt.registerSingletonAsync<ThemeService>(
    (_) => Future<ThemeService>.value(ThemeService()),
    dependsOn: <Type>[AndroidDetails],
  );

I keep getting The method <method name> was called on null since I'm using _details.<method name>().

Here's my ThemeService constructor:

  ThemeService() {
    _details = getIt.get<AndroidDetails>();
    settings = Hive.box<dynamic>(DatabaseHelper.SETTINGS_BOX);
  }

Am I doing something wrong? Should I be using getAsync?

EDIT: Here's my AndroidDetailsImplementation init() function:

  Future<void> init() async {
    try {
      final AndroidDeviceInfo _deviceInfo = await DeviceInfoPlugin().androidInfo;
      _deviceData = getDeviceData(_deviceInfo);
    } on PlatformException {
      _deviceData = <String, dynamic>{
        'Error:': 'Failed to get platform version.',
      };
    }
  }

I think I fixed the issue by using the Completer manually and awaiting it in my main() function.

@Reprevise This will change mostly back to the way before with a lot of improvements

[Reprevise]

Sounds good @escamoteur, what kind of improvements will there be?

[escamoteur]

async factories with dependencies but easier to use
also a new registerSingletonWithDependencies

[Reprevise]

Sounds cool! What version will these changes be released on? The next one?

[escamoteur]

Yep, I guess next week
