Describe the bug
If a pub workspace contains flutter packages, we should use flutter pub instead of dart pub.

To Reproduce
Steps to reproduce the behavior:

If you'd like me to create a simple repro, I can.

Expected behavior
Even if the flutter package is not the one being saved (or shown in the IDE), we should detect it and make sure the workspace root pub commands are using flutter instead of dart.
