Dependency Mismatch Error

  flutter:
    sdk: flutter
  flutter_bloc: ^0.19.0
  chopper: ^2.4.2
  built_value: ^6.7.0
  kiwi: ^0.2.0
  shared_preferences: ^0.5.3+4
  url_launcher: ^5.1.1
  event_bus: ^1.1.0
  flutter_sms: ^1.0.1
  rxdart: ^0.22.0
  rxbus: ^0.0.2`

After adding rxbus I am getting the following error:

Running "flutter pub get" in example_project...                    

Because example_project depends on rxbus ^0.0.2 which depends 
on rxdart ^0.20.0, rxdart ^0.20.0 is required.
So, because example_project depends on rxdart ^0.22.0, 
version solving failed.
pub get failed (1)
Process finished with exit code 1

I guess you need to upgrade your RxDart version to latest.

I also meet this error. I can't use flutter-bloc, because this package has old rxdart dependency
