Deployment and Distribution

Welcome to the Deployment and Distribution guide! In this section, we'll cover building and releasing Flutter apps, app store deployment for Google Play Store and Apple App Store, and Continuous Integration/Continuous Deployment (CI/CD) for Flutter.

Building and Releasing Flutter Apps

Building and releasing a Flutter app involves running the following commands:

flutter build apk   # For Android
flutter build ios   # For iOS

To release, follow platform-specific steps for signing and packaging.

App Store Deployment

Google Play Store

Generate a keystore:

keytool -genkey -v -keystore key.keystore -keyalg RSA -keysize 2048 -validity 10000 -alias key

Build the release APK:

flutter build appbundle

Upload the generated bundle to the Google Play Console.

Apple App Store

Set up Xcode project settings.

Archive your app in Xcode.

Upload the archive to App Store Connect.

Continuous Integration/Continuous Deployment (CI/CD) for Flutter

Use CI/CD tools like Jenkins, Travis CI, or GitHub Actions to automate testing, building, and deploying your Flutter app.

Here's an example GitHub Actions workflow:

name: CI/CD

on:
  push:
    branches:
      - main

jobs:
  build:
    runs-on: ubuntu-latest

    steps:
      - name: Checkout repository
        uses: actions/checkout@v2

      - name: Set up Flutter
        uses: subosito/flutter-action@v2
        with:
          flutter-version: '2.8.0'  # Set your Flutter version

      - name: Get dependencies
        run: flutter pub get

      - name: Run tests
        run: flutter test

      - name: Build release APK
        run: flutter build apk

      - name: Deploy to Google Play
        uses: wzieba/FakeGooglePlay@v1
        with:
          artifacts: build/app/outputs/flutter-apk/app-release.apk
          track: internal
          rollout: 1%
