Im running it with:

Framework • revision 007a415c2a (5 days ago) • 2019-02-21 20:22:47 -0800
Engine • revision f1f19bba8f
Tools • Dart 2.2.0 (build 2.2.0-dev.2.1 c92d5ca288)

¿Any idea on what could be making this fail?

I think i found the problem, it works with rxdart: 0.20.0 but not with rxdart 0.21.0

@rafahsolis just update the pubspec.yaml to use the latest flutter_bloc.

flutter_bloc: ^0.7.0

This was due to a breaking change in RxDart 0.21.0. Sorry for the inconvenience!
