How to Publish a Flutter App to the App Store and Google Play

July 19, 2026

So you’ve built a stunning Flutter app with a beautiful UI, solid backend, and all the features your users love. Now comes the real challenge: getting it into the hands of millions through the App Store and Google Play. Many developers struggle with the intricacies of app store submission, code signing, and platform-specific requirements. This guide walks you through every step to publish your Flutter app successfully, saving you hours of trial and error. How to Publish a Flutter App to the App Store and Google Play deserves special attention here.

Key Prerequisites for Publishing a Flutter App

Before diving into the submission process, ensure you have the following in place:

Developer accounts: An Apple Developer account ($99/year) and a Google Play Developer account ($25 one-time).
Flutter SDK installed and configured for both iOS and Android builds.
Completed app with proper testing on real devices and emulators.
App assets: icons, splash screens, screenshots, and a privacy policy.

If you’re starting from a ready-made template from Webnum’s app templates, you already have a polished codebase with pre-configured assets, which speeds up the publishing process significantly. How to Publish a Flutter App to the App Store and Google Play is a key factor in this decision.

Preparing Your Flutter App for Release

Release preparation involves several critical steps that are easy to overlook. First, switch to release mode by running flutter build appbundle for Android or flutter build ios for iOS. Update the version number in pubspec.yaml and ensure your app’s package name and bundle identifier are unique. Set up your app icon and splash screen using tools like flutter_launcher_icons and flutter_native_splash. Review all permissions – only request what your app actually needs to avoid rejection. Finally, test the release build on a physical device.

Building and Signing the Android App

Generate a signed app bundle (AAB) using a keystore. Create a key.properties file in the android folder and reference it in android/app/build.gradle. Then run flutter build appbundle --release. The resulting .aab file will be in build/app/outputs/bundle/release/. Next, log in to the Google Play Console, create a new app, fill in the store listing (title, description, screenshots, category), and answer the content rating questionnaire. Upload your AAB file under the “Production” track, complete the pricing and distribution section, and submit for review. Review typically takes a few hours to a few days. Much depends on how How to Publish a Flutter App to the App Store and Google Play is implemented.

App Store Optimization Tips

Write a compelling description highlighting key features. Use at least 4–8 high-quality screenshots per device category. Localize your listing for major markets. Leverage Webnum’s custom app development expertise to align your store assets with best conversion practices.

How to Publish a Flutter App to the App Store

Publishing on the App Store requires more steps due to Apple’s stringent guidelines. How to Publish a Flutter App to the App Store and Google Play matters just as much in practice.

Building and Archiving for iOS

First, open the ios folder in Xcode. Set the signing team under “Signing & Capabilities”. Update the bundle identifier, version, and build number. Ensure your deployment target matches your app’s requirements. Run flutter build ios --release to produce the Release build. In Xcode, select “Any iOS Device (arm64)” as the destination and go to Product > Archive. Once the archive is built, the Organizer window opens. Click “Distribute App”, choose “App Store Connect”, and upload. If you have multiple certificates, ensure you have an App Store distribution certificate and a provisioning profile.

App Store Connect Setup

In App Store Connect, create a new app, enter the same bundle identifier, and fill out the app information: name, subtitle, privacy policy URL, description, keywords, and support URL. Upload screenshots for each device size. Configure the rating and set the pricing. After uploading the build from Xcode, select it in the “Build” section and submit for review. Apple’s review can take 24–48 hours. Common rejections include incomplete metadata, broken links, and missing privacy policies. That is exactly why How to Publish a Flutter App to the App Store and Google Play should not be underestimated.

Common Pitfalls and How to Avoid Them

Signing issues on iOS: Always use an App Store distribution certificate, not a development one. Check that your provisioning profile includes the correct app ID.
Google Play app signing key: If you lose your keystore, you cannot update the app. Backup your keystore safely. Alternatively, use Google Play App Signing.
Incomplete store listing: Both stores require a valid privacy policy. Use a template from Webnum’s GustViu Terms of Use as a starting point and customize it.
Missing in-app purchases setup: If you use subscriptions or purchases, configure them in both stores before submission.

Automating Deployment with CI/CD

To scale your releases, integrate continuous deployment using services like GitHub Actions, Codemagic, or Bitrise. These tools automate building, signing, and uploading to both stores. For example, you can set up a workflow that triggers on tag push, builds the Flutter app, and sends it to App Store Connect and Google Play Console. This is especially useful for teams releasing frequent updates. Pairing CI/CD with a solid Flutter widget architecture ensures maintainability.

Key Takeaways

Publishing a Flutter app to both stores involves careful preparation, platform-specific steps, and attention to detail. Key points to remember: In real projects, How to Publish a Flutter App to the App Store and Google Play requires a systematic approach.

Always test release builds on real devices before submission.
Use the correct signing configurations for each platform.
Complete all metadata fields and include a privacy policy.
Expect rejections and plan for them – they are part of the learning curve.
Leverage pre-built templates and custom development services to skip repetitive setup. Webnum offers 375+ app templates with full source code, ready to customize and publish.
