GitHub Action — Analyze Dart

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.

Usage

Pre-requisites

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.

Inputs

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

Outputs

None.

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

Flutter workflow

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

on: push

name: Sample Workflow

jobs:
  build:
    name: Example
    runs-on: ubuntu-latest
    steps:
      - name: Checkout code
        uses: actions/checkout@v2
      - name: Set up Flutter
        uses: subosito/flutter-action@v1
      - run: flutter pub get

        uses: zgosalvez/github-actions-analyze-dart@v2

Custom Workflow

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

Flutter Workflows

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