Deploying Flutter Apps to Play Store and App Store

Flutter has emerged as a leading cross-platform framework for developing beautiful, high-performance mobile applications. One of its most powerful features is the ability to deploy a single codebase to both Google Play Store (Android) and Apple App Store (iOS). However, deploying a Flutter app to these platforms involves multiple steps, including preparing builds, configuring accounts, and meeting each platform’s requirements.

In this blog, we’ll walk through the end-to-end process of deploying Flutter apps to both the Play Store and App Store.


๐Ÿงช Step 1: Prepare Your Flutter App for Release

Before deployment, ensure your app is production-ready:

Test thoroughly on multiple devices.

Remove debug prints and unnecessary packages.

Use release mode to build a performance-optimized binary.

Update app version and build number in pubspec.yaml:


yaml


version: 1.0.0+1


๐Ÿ“ฆ Step 2: Build APK or AAB for Android

Google recommends publishing AAB (Android App Bundle) instead of APK for optimized delivery.

Run the following command to build your AAB:


bash


flutter build appbundle

The output will be located in:

build/app/outputs/bundle/release/app-release.aab


๐Ÿ“ฑ Step 3: Create a Google Play Developer Account

Visit https://play.google.com/console

Pay a one-time registration fee ($25)

Set up your developer profile and accept the developer distribution agreement


๐Ÿš€ Step 4: Upload to Google Play Store

Go to the Play Console → Click "Create app"

Fill in the required metadata:

App name, description, icon, screenshots

Upload the .aab file

Fill in content rating, privacy policy URL, and target audience

Set up pricing and distribution countries

Submit for review under Production track

Google’s review process may take a few hours to a few days.


๐Ÿ Step 5: Build an iOS App Archive

Before submitting to the App Store, you'll need a macOS system with Xcode installed.

Build the app for release:

bash


flutter build ios --release

Open the ios/Runner.xcworkspace in Xcode

Configure:

Bundle Identifier

Versioning

Signing & Capabilities (use your Apple Developer credentials)

Archive and upload via Xcode’s Organizer


๐Ÿ’ณ Step 6: Set Up Your Apple Developer Account

Go to https://developer.apple.com

Enroll in the Apple Developer Program ($99/year)

Access App Store Connect and Certificates, Identifiers & Profiles


๐Ÿ“ค Step 7: Submit to App Store

Open App Store Connect

Click "My Apps" → "+" to create a new app

Fill out:

App name, SKU, platform, bundle ID

Metadata (description, keywords, screenshots, app icon)

Assign the uploaded build from Xcode

Add Privacy Policy and App Review Notes

Submit for review

Apple’s review process can take 1–3 days (or more during peak times).


๐Ÿง  Tips for Smooth Deployment

Keep icons and screenshots in required resolutions

Follow content guidelines to avoid rejections

Regularly update versions and changelogs

Automate builds and testing with CI/CD tools like GitHub Actions or Codemagic


✅ Conclusion

Deploying Flutter apps to the Play Store and App Store can seem daunting, but with a clear understanding of the steps and requirements, it becomes a smooth process. With Flutter, your single codebase can reach millions of Android and iOS users. Take your time to test thoroughly, follow each platform’s rules, and your app will be live and ready to make an impact in no time!
