We recently changed flutter so that you need to run flutter packages get, not pub get.
However, some (many?) status messages still say that we are running pub get thus potentially causing confusion. For example, when running flutter for the first time:
$ flutter doctor
Downloading Material fonts... 2.2s
Downloading package sky_engine... 1.4s
Running 'pub get' in sky_engine... 0.4s
Downloading package sky_services... 0.4s
Running 'pub get' in sky_services... 3.1s
Downloading package flutter_services... 0.3s
Running 'pub get' in flutter_services... 1.7s
