Dart 2.18.7 issue with pub

If you run a codemod and haven't performed a pub-get beforehand, the codemod will attempt to pub-get. By default, we can no longer run 'pub get' and instead must run 'dart pub get'. (Or setup an alias)

Running the codemod in this instance produces this error:

dustinpauze@WF17853 wdesk_sdk % dart pub global run over_react_codemod:intl_message_migration

Start with package:over_react_codemod/src/util/package_util.dart at runPubGet, then trace its callers in src/executables/intl_message_migration.dart. Reproduce the codemod without a prior dependency fetch; done means the dependency step uses the Dart-compatible command and completes instead of failing with exit code 126.
