Note regarding how this workes with pub workspaces

[Jonas-Sander]

Pub workspaces is a new feature that when used removes stray package_config.json from packages inside the workspace.

When trying to run license_checker on these packages one will get the following error:

Filtering out approved packages ...
Loading config from ../licenses_config.yaml ...
Checking all dependencies ...
No package_config.json found. Are you sure this is a Dart package directory?

To fix this one can navigate to the root pubspec.yaml an run the tool there.
This will check the licenses for all packages inside the workspace.
The root pubspec.yaml will look something like this:

name: _
publish_to: none
environment:
  sdk: ^3.6.2
workspace:
  - packages/helper
  - packages/client_package
  - packages/server_package

Maybe this explanation could be added to the README?
This could also be hinted at when using the tool inside a package that uses pub workspace.

Thanks Jonas. I can confirm that this works. I was before using -d (check only direct dependencies) flag and checked licenses on each monorepo packages using melos. When configuration of license checker is moved to root of monorepo / workspace one needs to remove -d flag and check that also all transitive dependencies have license. Melos is not needed after this change anymore. I needed to do minor modifications to config, which was trivial. Without this message I might have not come to this idea. Thanks for sharing.
