This GitHub Action (written in JavaScript) allows you to leverage GitHub Actions to analyze your Dart project's Dart code, including Flutter. This runs both the dart analyze and dartfmt commands under the hood.

Create a workflow .yml file in your .github/workflows directory. An example workflow is available below. For more information, reference the GitHub Help Documentation for Creating a workflow file.

For more information on these inputs, see the Workflow syntax for GitHub Actions

• fail-on-infos: The action fails if any info was found. This will always fail on errors. Optional. Default: false
• fail-on-warnings: The action fails if any warning was found. This will always fail on errors. Optional. Default: false
• working-directory: The working directory. Optional. Default: ./
• line-length: The maximum line length. Optional. The formatter will use its default: 80

Sample Files Changed:

1. Your workflow must install Dart before using this action. Suggestion: Dart starter workflow.
2. Use the action. For example:

on: push

name: Sample Workflow

jobs:
  build:
    name: Example
    runs-on: ubuntu-latest
    container:
      image:  google/dart:latest
    steps:
      - name: Checkout code
        uses: actions/checkout@v2
      - name: Install dependencies
        run: dart pub get
      - name: Analyze Dart
        uses: zgosalvez/github-actions-analyze-dart@v1

After following the common workflow above, lint rules can be customized. For more details see:

• pedantic for rules enforced internally at Google
• effective_dart for rules corresponding to the Effective Dart style guide

This is used in my opinionated GitHub Actions: Flutter Workflows repository along with other actions for a complete end-to-end DevOps experience.
