Publishing procedure

This GitHub Action is published to the GitHub Actions Marketplace here: https://github.com/marketplace/actions/setup-dart-sdk

Follow these steps to publish a new version:

1. Land the changes via PRs

2. Make sure the CHANGELOG.md is updated

3. Get confirmation that the changes work by having someone use the new version using a commit tag, e.g.:

   • - uses: dart-lang/setup-dart@9a04e6d73cca37bd455e0608d7e5092f881fd603

4. Use the GitHub flow for creating a new release with a release tag (e.g. v1.3.0):

   • Navigate to https://github.com/dart-lang/setup-dart/releases
   • Click 'Draft a new release'
   • Towards the bottom of the page, click the 'Choose a tag' box and then enter a tag (e.g. v1.3.0)
   • In the release notes field below, paste in the relevant text from the changelog

5. Move the v1 tag to point to the latest v1.x.y release as per the GitHub guidance:

   • Find the commit tag: git log --pretty=oneline
   • Move the v1 tag it: git tag -f v1 [commit tag]
   • Validate everything went as planned: git show v1
   • Push the tag to the origin repo: git push -f origin v1
   • Validate the new repo tag: git ls-remote --tags [email protected]:dart-lang/setup-dart.git v1
