  • Dependency Mismatch Error

    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.

  • Concurrent modification during iteration

    Concurrent modification during iteration

    static void destroy({tag}) { _list.forEach((rxBus) { if (tag != null && tag != _DEFAULT_IDENTIFIER && rxBus.tag == tag) { rxBus.subject.close(); _list.remove(rxBus); } else if ((tag == null || tag == _DEFAULT_IDENTIFIER) && rxBus.tag == _DEFAULT_IDENTIFIER) { rxBus.subject.close(); _list.remove(rxBus); } }); } 在进行迭代循环时试图删除list中内容，导致异常抛出，建议的修改方案如： ///事件关闭 static void destroy({tag}) { var toRemove = []; _list.forEach((rxBus) { if (tag != null && tag != _DEFAULT_IDENTIFIER && rxBus.tag == tag) { rxBus.subject.close(); toRemove.add(rxBus); } else if ((tag == null || tag == _DEFAULT_IDENTIFIER) && rxBus.tag == _DEFAULT_IDENTIFIER) { rxBus.subject.close(); toRemove.add(rxBus); } }); toRemove.forEach((rxBus) { _list.remove(rxBus); }); }
