flutter-action

Flutter environment for use in GitHub Actions. It works on Linux, Windows, and macOS.

The following sections show how to configure this action.

Specifying Flutter version

Use specific version and channel

steps:
  - name: Clone repository
    uses: actions/checkout@v4
  - name: Set up Flutter
    uses: subosito/flutter-action@v2
    with:
      channel: stable
      flutter-version: 3.19.0
  - run: flutter --version

Use version from pubspec.yaml

This is inspired by actions/setup-go.

steps:
  - name: Clone repository
    uses: actions/checkout@v4
  - name: Set up Flutter
    uses: subosito/flutter-action@v2
    with:
      channel: stable
      flutter-version-file: pubspec.yaml # path to pubspec.yaml
  - run: flutter --version

Important

For flutter-version-file to work, you need to have the exact Flutter version defined in your pubspec.yaml:

Good

environment:
  sdk: ">=3.3.0 <4.0.0"
  flutter: 3.19.0

Bad

environment:
  sdk: ">=3.3.0 <4.0.0"
  flutter: ">= 3.19.0 <4.0.0"

Warning

Using flutter-version-file requires yq, which is not pre-installed in windows images. Install it yourself.

Use latest release for particular channel

steps:
  - name: Clone repository
    uses: actions/checkout@v4
  - name: Set up Flutter
    uses: subosito/flutter-action@v2
    with:
      channel: stable # or: beta, master (or main)
  - run: flutter --version

Use latest release for particular version and/or channel

steps:
  - name: Clone repository
    uses: actions/checkout@v4
  - name: Set up Flutter
    uses: subosito/flutter-action@v2
    with:
      channel: dev
      flutter-version: 1.22.x
  - run: flutter --version

Use particular version on any channel

steps:
  - name: Clone repository
    uses: actions/checkout@v4
  - name: Set up Flutter
    uses: subosito/flutter-action@v2
    with:
      channel: any
      flutter-version: 3.x
  - run: flutter --version

Use particular git reference on master channel

steps:
  - name: Clone repository
    uses: actions/checkout@v4
  - name: Set up Flutter
    uses: subosito/flutter-action@v2
    with:
      channel: master
      flutter-version: 5b12b74 # tag, commit or branch
  - run: flutter --version

Build Target

Build Android APK and app bundle:

steps:
  - name: Clone repository
    uses: actions/checkout@v4
  - name: Set up Flutter
    uses: subosito/flutter-action@v2

      - name: Set up Flutter
        uses: subosito/flutter-action@v2
        with:
          channel: stable
      - run: flutter pub get
      - run: flutter test
      - run: flutter build ios --release --no-codesign

Build for the web

steps:
  - name: Clone repository

        uses: subosito/flutter-action@v2
        with:
          channel: stable
      - run: flutter build windows

Build for Linux desktop

jobs:
  main:
    runs-on: ubuntu-latest
    steps:
      - name: Clone repository
        uses: actions/checkout@v4
      - name: Set up Flutter
        uses: subosito/flutter-action@v2
        with:
          channel: stable
      - run: |
          sudo apt-get update -y
          sudo apt-get install -y ninja-build libgtk-3-dev
      - run: flutter build linux

Build for macOS desktop

Note

Building for macOS requires a macOS runner.

jobs:
  main:
    runs-on: macos-latest
    steps:
      - name: Clone repository
        uses: actions/checkout@v4
      - name: Set up Flutter
        uses: subosito/flutter-action@v2
        with:
          channel: stable
      - run: flutter build macos

Caching

Integration with actions/cache:

steps:
  - name: Clone repository
    uses: actions/checkout@v4
  - name: Set up Flutter
    uses: subosito/flutter-action@v2
    with:
      channel: stable
      cache: true
      # optional parameters follow
      cache-key: "flutter-:os:-:channel:-:version:-:arch:-:hash:" # optional, change this to force refresh cache
      cache-path: "${{ runner.tool_cache }}/flutter/:channel:-:version:-:arch:" # optional, change this to specify the cache path
      pub-cache-key: "flutter-pub:os:-:channel:-:version:-:arch:-:hash:" # optional, change this to force refresh cache of dart pub get dependencies
      pub-cache-path: "${{ runner.tool_cache }}/flutter/:channel:-:version:-:arch:" # optional, change this to specify the cache path
  - run: flutter --version

Note: cache-key, pub-cache-key, and cache-path have support for several dynamic values:

:os:
:channel:
:version:
:arch:
:hash:
:sha256:

Use outputs from flutter-action:

steps:
  - name: Clone repository
  - uses: actions/checkout@v4
  - name: Set up Flutter
    uses: subosito/flutter-action@v2
    id: flutter-action
    with:
      channel: stable
  - name: Print outputs
    shell: bash
    run: |
      echo CACHE-PATH=${{ steps.flutter-action.outputs.CACHE-PATH }}
      echo CACHE-KEY=${{ steps.flutter-action.outputs.CACHE-KEY }}
      echo CHANNEL=${{ steps.flutter-action.outputs.CHANNEL }}
      echo VERSION=${{ steps.flutter-action.outputs.VERSION }}
      echo ARCHITECTURE=${{ steps.flutter-action.outputs.ARCHITECTURE }}
      echo PUB-CACHE-PATH=${{ steps.flutter-action.outputs.PUB-CACHE-PATH }}
      echo PUB-CACHE-KEY=${{ steps.flutter-action.outputs.PUB-CACHE-KEY }}

If you don't need to install Flutter and just want the outputs, you can use the dry-run option:

steps:
  - name: Clone repository
  - uses: actions/checkout@v4
  - name: Set up Flutter
    uses: subosito/flutter-action@v2
    id: flutter-action
    with:
      channel: stable
      dry-run: true
  - run: |
      echo CACHE-PATH=${{ steps.flutter-action.outputs.CACHE-PATH }}
      echo CACHE-KEY=${{ steps.flutter-action.outputs.CACHE-KEY }}
      echo CHANNEL=${{ steps.flutter-action.outputs.CHANNEL }}
      echo VERSION=${{ steps.flutter-action.outputs.VERSION }}
      echo ARCHITECTURE=${{ steps.flutter-action.outputs.ARCHITECTURE }}
      echo PUB-CACHE-PATH=${{ steps.flutter-action.outputs.PUB-CACHE-PATH }}
      echo PUB-CACHE-KEY=${{ steps.flutter-action.outputs.PUB-CACHE-KEY }}
    shell: bash
