Custom lint not working on Monorepo

[hpelitebook745G2]

Describe the bug
I have a monorepo with a lot of packages, each package is either a Dart or Flutter project. I want to apply my custom lint at the very root so I don't need to tediously update all pubspec.yaml but it's not working.

To Reproduce

I've been reading the issues here but what worked for me is to apply:

dev_dependencies:
  custom_lint: ^0.6.4
  custom_lint_example_lint:
    path: ../example_lint

to each of the packages and I have more than 20. Is it even possible to apply once and analyze all the code in my monorepo? If so, I haven't found any instructions in the README. Please advise.

Expected behavior
Apply once, analyze anywhere
