Add auto publish action #73

GitHub Actions Workflows #73

These workflows automatically update your package's phone number metadata and publish to pub.dev.

Metadata Update Workflow (metadata-update.yml)

This workflow runs on the 1st of each month and:

• Downloads new phone number metadata from Google's libphonenumber
• Updates package files with new data
• Increases package version number
• Creates a git tag with new version (e.g. 'v1.2.3')
• Pushes changes to GitHub

Publish Workflow (publish.yml)

This workflow automatically triggers when a version tag is pushed and:

• Starts when metadata workflow creates a new version tag
• Uses Dart's official process to publish to pub.dev
• Uses secure OIDC authentication - no manual tokens needed

Setup Required (for owner)

1. Add both workflow files to .github/workflows/
2. Enable GitHub Actions permissions:

• Go to repository Settings → Actions → General
• Enable "Read and write permissions"
• Enable "Allow GitHub Actions to create and approve pull requests"

3. Verify pub.dev publisher status:

• Login to pub.dev
• Verify publishing rights for package
• Ensure Google Account is verified

The workflows will then automatically update and publish the package monthly.

LGTM Thank you @ManindraDeMel I will try it out later this evening

I ran the update metadata workflow, but there is the following issues:

• the update metadata makes an update and patches the pubspec version regardless if there is any change or not. It has created a 9.0.4 tag on github while there was no change for instance. (I removed it)
• the publish action did not run at all for some reason.
• there currently is no entry added to changelog.md

A command to get the number of modified files git status -s -uno | wc -l ( to be run before dart pub bump patch but after file generation). I'm investigating why publish hasn't run at all

@ManindraDeMel I had created this issue with flutter tools in the past which is relevant to this:
