## What it is
A GitHub Action that sets up a Flutter environment in CI workflows, supporting version pinning, channels, and version files. It works on Linux, Windows, and macOS runners.

## Use cases
- set up flutter in github actions ci
- pin a specific flutter version in a workflow
- read flutter version from pubspec.yaml in CI
- build and test flutter apps on multiple OS runners
- use a flutter mirror for faster downloads in CI

## When to choose
- you build or test Flutter/Dart apps in GitHub Actions
- you need reproducible Flutter versions across CI jobs
- you want cross-platform Flutter CI on Linux, macOS, and Windows runners

## When to avoid
- you use GitLab CI, CircleCI, or other non-GitHub CI systems
- you need a local Flutter installation rather than CI setup
- your project does not use Flutter or Dart

## Facets
- artifact type: plugin
- maturity: active
- function: developer-tools, ci-cd, deployment
- domain: developer-tools, mobile-development
- platform: windows
- tags: github-actions, flutter, dart, ci-setup, workflow-action, devops, linux, macos, docker
