Consider the new Automated Publishing documentation
Description
Given the new Automated Publishing documentation, we should evaluate it and see how they impact some of our publish workflows.
If you'd like to move to the new ODIC flow, I've written an example that works: https://github.com/shorebirdtech/updater/blob/f37fee86a9fb1849d8a15da267a2de062d9e17d8/.github/actions/publish_flutter_package/action.yaml
We have updated all of our Dart/Flutter packages to use the https://github.com/dart-lang/setup-dart action. This sets up the needed pub.dev token without having to do the work by hand which @eseidel linked to.
Next step would be to update the workflows here to allow for not passing in a pub token and instead just doing the Dart Setup step automatically.
