Fastlane Flutter + GitLab CI/CD - Release App Senang Gila!

Apa ni?

Hai! Aku tau kau penat upload app kat PlayStore/AppStore. Setiap kali nak release tu, confirm leceh gila!

So, hari ni aku tunjuk cara automate semua tu! Guna Fastlane + GitLab CI/CD. Lepas ni, semua jadi automatik!

Kau Kene Ada

• Flutter project
• GitLab repository (bole guna gitlab.com free)
• Apple Developer Account (kalau nak upload ke AppStore)
• Google Play Console
• Firebase project dengan App Distribution

Step 1: Install Fastlane

Install Fastlane:

cd your-flutter-project
gem install fastlane

Step 2: Initialize

Jalan command ni:

fastlane init

Pilih option:

• iOS untuk AppStore/TestFlight
• Android untuk PlayStore

Step 3: iOS Fastlane

Create ios/fastlane/Fastfile:

default_platform(:ios)

platform :ios do
  desc "Beta ke TestFlight"
  lane :beta do
    increment_build_number
    build_app(
      scheme: "YourApp",
      workspace: "ios/YourApp.xcworkspace",
      configuration: "Release"
    )
    upload_to_testflight
  end

  desc "Release ke AppStore"
  lane :release do
    increment_build_number
    build_app(
      scheme: "YourApp",
      workspace: "ios/YourApp.xcworkspace",
      configuration: "Release"
    )
    upload_to_app_store
  end
end

Step 4: Android Fastlane

Create android/fastlane/Fastfile:

default_platform(:android)

platform :android do
  desc "Staging ke Firebase App Distribution"
  lane :staging do
    gradle(task: "assembleRelease")
    firebase_app_distribution(
      app_id: "1:123456789:android:abcdef",
      testers: "tester@example.com",
      release_notes: "Staging build terbaru!"
    )
  end

  desc "Production ke PlayStore"
  lane :production do
    gradle(task: "assembleRelease")
    upload_to_play_store(
      track: "production",
      apk: "app/build/outputs/apk/release/app-release.apk"
    )
  end
end

Step 5: GitLab CI/CD

Create .gitlab-ci.yml:

stages:
  - build
  - deploy

build_ios:
  stage: build
  image: macos-13-xcode-14
  before_script:
    - bundle install
    - flutter pub get
  script:
    - fastlane ios beta
  only:
    - develop

build_android_staging:
  stage: build
  image: ubuntu:latest
  before_script:
    - apt-get update && apt-get install -y ruby ruby-dev
    - gem install fastlane
    - flutter pub get
  script:
    - fastlane android staging
  only:
    - develop

build_android_production:
  stage: deploy
  image: ubuntu:latest
  before_script:
    - apt-get update && apt-get install -y ruby ruby-dev
    - gem install fastlane
    - flutter pub get
  script:
    - fastlane android production
  only:
    - main

Step 6: Secrets

Setup secrets kat GitLab:

• FASTLANE_USER - Apple ID email
• FASTLANE_PASSWORD - Apple ID password
• APP_STORE_CONNECT_API_KEY - API Key from AppStore Connect
• PLAY_STORE_JSON_KEY - Service Account from Google Play
• FIREBASE_TOKEN - Firebase token

Step 7: Push!

Push code kau:

git add .
git commit -m "Add Fastlane CI/CD"
git push origin develop  # Staging!
git push origin main    # Production!

Settled!

Sekarang:

• Develop branch → Firebase App Distribution (Staging)
• Main branch → PlayStore/AppStore (Production)

Kau sekarang dah separuh pro! Manual upload habis!
