Flutter combined with GitHub Actions Best Practices (CI/CD)

Goal

Implements robust CI/CD pipelines using GitHub Actions for Flutter projects. GitHub Actions is the most popular CI/CD platform for open-source and small-to-medium projects. By configuring YAML files under .github/workflows/, you can achieve high automation.

Instructions

1. Environment Setup & Core Setup

In all Flutter Workflows, the core package to use is the third-party maintained subosito/flutter-action.

Best Practices:

1. Bind the Flutter Version: Never use channel: stable or let it automatically fetch the latest version. Explicitly specify flutter-version or use flutter-version-file: pubspec.yaml to guarantee the CI environment exactly matches the local development environment.
2. Enable Cache: flutter pub get is a time-consuming step. Always enable cache: true.
