    Strong-mode analysis of lib/src/message_bus_impl.dart failed with the following error:

    line: 24 col: 2
    Invalid override. The type of 'MessageBusImpl.undeliverableHandler=' ('(Function) → void') isn't a subtype of 'MessageBus.undeliverableHandler=' ('(dynamic) → void').

  • Fix issues reported by dartanalyzer.

    dartanalyzer reported 1 error(s) and 0 warning(s).

  • The description is too short.

    Add more detail about the package, what it does and what is its target use case. Try to write at least 60 characters.

  • Package is pre-v1 release.

    While there is nothing inherently wrong with versions of 0.*.*, it usually means that the author is still experimenting with the general direction API.
