Could not find a command named "doc".

[evanholt1]

Greetings!

I know this may be quite trivial,, but when following this guide:
https://dart.dev/tools/dart-doc
to generate dartdoc for my flutter app,
what i get on the terminal when running dart doc .
from the root directory of my flutter app
is just Could not find a command named "doc".

my dart version is
Dart SDK version: 2.15.1 (stable) (Tue Dec 14 13:32:21 2021 +0100) on "linux_x64",
and i have ran dart pub get successfully on the project beforehand.

I also did install and globally activate
https://pub.dev/packages/dartdoc,
but running dart doc . or dartdoc . neither work.
running dart help doc throws the same command,
and running dart help shows me the available commands, none of which is doc.
