Versioning

Pin a full commit SHA of a release tag (most secure, Semgrep standard), with the version in a comment:

uses: dotsem/actions/.github/workflows/flutter-ci.yml@<40-char-sha> # v0.5.0

Or pin a minor tag (convenient, receives patch fixes):

uses: dotsem/actions/.github/workflows/flutter-ci.yml@v0.5

Resolve a SHA with git ls-remote https://github.com/dotsem/actions 'refs/tags/v0.5.0^{}'. Only SHAs of release tags pin the whole tree; a SHA from main still contains @main self-references.

Ref Moves on Use
@<sha> never Recommended (recommended by SemGrep): immutable, full reproducibility
@v0.5 patch releases of 0.5 Recommended: bug fixes, no breaking changes
@v0.5.0 never (tag can be moved) Readable, but tags are mutable
@v0 every 0.x release Not recommended: during 0.x, minor releases may break you

Every release tag pins the whole tree. Reusable workflows and actions that call other actions in this repo get those references rewritten to the same release tag, so flutter-ci.yml@v0.5.0 always runs build-flutter@v0.5.0. On main, self-references are @main.

Release notes: GitHub Releases.

Permissions

Examples assume a public repository. In a private repository, actions/checkout needs contents: read, so every job using these actions (or flutter-ci.yml) must grant it:

permissions:
    contents: read # required for private repos; optional for public

Reusable workflows can only narrow the caller's token permissions, never widen them. Grant the permissions listed under each workflow in the calling job.

Flutter CD (flutter-cd.yml)

Builds release packages across specified platforms and uploads them directly to a GitHub release.

Permissions Required

    contents: write # for uploading release assets

Flutter Version

unless flutter-version is passed, the SDK version is read from environment.flutter in <working-directory>/pubspec.yaml. An exact version is recommended; a range (^3.47.1, ">=3.47.1 <4.0.0") installs its lower bound:

environment:
    sdk: ^3.13.1
    flutter: 3.47.1

Inputs

Name Description Required Default
targets JSON array of targets to build (e.g. '["linux", "windows"]') Yes -
tag Target release tag (defaults to event tag or ref) No ""
flutter-version Flutter SDK version (empty reads environment.flutter from pubspec.yaml) No ""
working-directory Directory containing pubspec.yaml No "."

Secrets

Name Description Required
token GitHub token with write access (defaults to GITHUB_TOKEN) No

Usage

# .github/workflows/release.yml
name: Release

on:
    release:
        types: [published]
    workflow_dispatch:
        inputs:
            tag:
                description: "Release tag"
                required: false

    group: ${{ github.workflow }}-${{ github.ref }}
    cancel-in-progress: false

    cd:
        uses: dotsem/actions/.github/workflows/flutter-cd.yml@v0.5
        permissions:
            contents: write
        with:
            targets: '["linux", "windows", "macos", "android-aab"]'
            tag: ${{ inputs.tag || github.event.release.tag_name }}

Releasing (maintainers)

  1. Merge to main with conventional-commit PR titles; these become the release notes.
  2. Run the Release workflow (internal-release.yml) from main with a version, e.g. 0.5.0 or 0.5.0-rc.1.
  3. The workflow:
    • rewrites every dotsem/actions/...@main self-reference to @v<version> in a detached release commit
    • tags it v<version> and creates a GitHub release with generated notes
    • moves v0 and v0.<minor> to the new tag (skipped for pre-releases)

Authenticates as a GitHub App (short-lived token, scoped to this repo), because GITHUB_TOKEN can't push commits that modify .github/workflows/. Requires:

  • repository variable RELEASE_APP_CLIENT_ID: the app's Client ID
  • repository secret RELEASE_APP_PRIVATE_KEY: the app's private key
  • app repository permissions Contents: read & write and Workflows: read & write, installed on this repo only

Bump the minor version for breaking changes and the patch version for everything else.
