You can automated job matrix across multiple version of Flutter SDK by using flutter-actions/pubspec-matrix-action action. This GitHub Action generates a matrix of Dart and Flutter SDK versions from a pubspec.yaml file.

If you are running this on self-hosted runner specially with Apple Silicon Mac only Flutter SDK v3.0.0 or later are supported.

Starting from flutter-actions/setup-flutter@v3, the action will disable Flutter SDK built-in Google Analytics by default.

This action is designed to be used in GitHub Actions environment. If you want to use it outside of GitHub Actions, you can use the following script:

# Usage:
#     curl -fsSL https://raw.githubusercontent.com/flutter-actions/setup-flutter/main/install.sh | bash -s -- <version> <channel>
# 
# Example:

export SETUP_FLUTTER_BRANCH=main
curl -fsSL https://raw.githubusercontent.com/flutter-actions/setup-flutter/${SETUP_FLUTTER_BRANCH}/install.sh | bash -s -- 3.0.2 stable
