FVM manages Flutter SDK versions per project. Switch between Flutter versions instantly without reinstalling, making it easy to test new releases and maintain consistent builds across your team.

Why FVM?

• Need for simultaneous use of multiple Flutter SDKs.
• SDK testing requires constant channel switching.
• Channel switches are slow and need repeated reinstalls.
• Difficulty managing the latest successful SDK version used in an app.
• Flutter's major updates demand total app migration.
• Inconsistencies occur in development environments within teams.

For more information, read the Getting Started guide.

Release Process (For Maintainers)

FVM uses GitHub releases to trigger automated deployments across all platforms:

Creating a New Release

1. Ensure main branch is ready

   • All changes merged and tested
   • Version will be set automatically from release tag

2. Create GitHub Release

   • Go to GitHub Releases
   • Click "Create a new release"
   • Choose tag: v4.0.0-beta.2 (follows semver with 'v' prefix)
   • Write release notes in GitHub editor
   • Click "Publish release"

3. Automated Deployment

   • release.yml triggers automatically
   • Deploys to: pub.dev, GitHub binaries, Homebrew, Chocolatey, Docker
   • Monitor progress in Actions tab

Dart SDK requirements: Day-to-day development now targets the repository SDK constraint (>=3.6.0 <4.0.0). Release automation lives under tool/release_tool/ and requires Dart SDK >=3.8.0. CI pins this higher tool chain via the RELEASE_DART_SDK environment variable (currently 3.9.0) so it matches the versions packaged for Homebrew and other installers. If you run release tasks locally, switch to a Dart SDK 3.8.0 or newer before executing commands from tool/release_tool/.

Emergency Releases

For hotfixes or emergency releases:

1. Update version manually in pubspec.yaml
2. Use individual platform workflows via manual dispatch:
   • deploy_homebrew.yml for Homebrew updates
   • deploy_docker.yml for Docker deployment
   • Individual platform deployments as needed

For complete emergency deployment, create a GitHub release as normal.

See Workflow Documentation for detailed information.
