Incompatible version constraints on Intl (flutter_architecture_samples -> redux)

Hi there.

After downloading the example from https://gitlab.com/brianegan/flutter_architecture_samples/tree/master/example/redux (the entire repo) and running flutter packages get, I get this error:

[redux] flutter packages get
Running "flutter packages get" in redux...
Incompatible version constraints on intl:
- flutter_architecture_samples 0.0.1 depends on version 0.15.1
- flutter_driver 0.0.0 depends on version 0.15.4
pub get failed (1)
exit code 1
