I was simply following a tutorial explaining the use of Pigeon...

https://pub.dev/packages/pigeon/example

[stuartmorgan-g]

The file that imports the pigeon package in that example is a stand-alone file that is used to generate code in the next step. It's not part of a Flutter application.

I'll mark this as a documentation issue to make that more explicit.
