🔐 Secure OIDC authentication (no API tokens needed)
📦 Multi-package support with parallel execution
✅ Pre-publish validation (analyze, test, dry-run)
🎯 Fail-safe mode (continues on individual package failures)

Usage

name: Publish Packages

on:
  release:
    types: [published]

jobs:
  publish:
    uses: btwld/dart-actions/.github/workflows/publish.yml@main
    with:
      packages_folder_path: "packages"
      packages: |
        my_package
        another_package
        third_package

Inputs

Input	Description	Required	Example
`packages_folder_path`	Path to the folder containing packages	Yes	`"packages"`
`packages`	List of package names to publish (one per line)	Yes	See example above

What It Does

For each package:

Checkout - Clones the repository
Setup - Installs Dart and Flutter
Dependencies - Runs flutter pub get
Analysis - Runs flutter analyze
Testing - Runs flutter test
Dry Run - Tests publishing with dart pub publish --dry-run
Publish - Publishes to pub.dev using OIDC authentication

Requirements

Your repository must be set up for OIDC publishing
The workflow requires id-token: write permission (already configured)
A "Production" environment should be configured in your repository settings

Quick Start

1. Add Workflows to Your Repository

Create a .github/workflows directory in your repository and add your workflow files:

# .github/workflows/ci.yml
name: CI

on:
  pull_request:
  push:
    branches: [main]

jobs:
  ci:
    uses: btwld/dart-actions/.github/workflows/ci.yml@main
    secrets:
      token: ${{ secrets.GITHUB_TOKEN }}

# .github/workflows/pr-check.yml
name: PR Checks

on:
  pull_request:
    types: [opened, edited, synchronize, reopened]

jobs:
  title-check:
    uses: btwld/dart-actions/.github/workflows/pr-title-check.yml@main

# .github/workflows/publish.yml
name: Publish

on:
  workflow_dispatch:
    inputs:
      packages:
        description: 'Package names (comma-separated)'
        required: true

jobs:
  publish:
    uses: btwld/dart-actions/.github/workflows/publish.yml@main
    with:
      packages_folder_path: "packages"
      packages: ${{ inputs.packages }}

2. Required Permissions

Ensure your workflows have the necessary permissions:

permissions:
  contents: read        # For checkout
  pull-requests: write  # For PR comments
  id-token: write      # For OIDC publishing

3. Repository Setup

For publishing to pub.dev:

Enable OIDC publishing in your pub.dev account
Configure a "Production" environment in your repository settings
Ensure your packages have proper version numbers and changelogs
