CI/CD for Flutter

Introduction

CI/CD helps you automatically build, test, and deliver your Flutter app. It saves time and reduces mistakes.

You want to test your Flutter app every time you change code.

You want to build app versions automatically for Android and iOS.

You want to deliver app updates faster to testers or users.

You want to catch errors early before releasing your app.

You want to keep your app quality high with automated checks.

Syntax

Flutter

name: flutter_ci
on: [push, pull_request]
jobs:
  build:
    runs-on: ubuntu-latest
    steps:
      - uses: actions/checkout@v3
      - uses: subosito/flutter-action@v2
        with:
          flutter-version: 'stable'
      - run: flutter pub get
      - run: flutter test
      - run: flutter build apk --release

This example uses GitHub Actions to run CI/CD for Flutter.

It runs on every push or pull request to check and build the app.

Examples

Basic commands to get packages, run tests, and build an Android app.

Flutter

flutter pub get
flutter test
flutter build apk --release

CI config to build iOS app on push using a specific Flutter version.

Flutter

name: flutter_ci
on: push
jobs:
  build:
    runs-on: macos-latest
    steps:
      - uses: actions/checkout@v3
      - uses: subosito/flutter-action@v2
        with:
          flutter-version: '3.7.0'
      - run: flutter pub get
      - run: flutter test
      - run: flutter build ios --release

Sample App

This GitHub Actions workflow runs when you push code. It checks out your code, sets up Flutter, gets packages, runs tests, and builds the Android app.

Flutter

name: flutter_ci
on: [push]
jobs:
  build:
    runs-on: ubuntu-latest
    steps:
      - uses: actions/checkout@v3
      - uses: subosito/flutter-action@v2
        with:
          flutter-version: 'stable'
      - run: flutter pub get
      - run: flutter test
      - run: flutter build apk --release

Important Notes

Use a CI service like GitHub Actions, GitLab CI, or Bitrise for Flutter CI/CD.

Always run tests before building to catch errors early.

For iOS builds, you need a macOS runner and proper signing setup.

Summary

CI/CD automates building and testing your Flutter app.

Use workflows to run commands like flutter pub get, flutter test, and flutter build.

This helps deliver better apps faster and with fewer mistakes.
