Building & Publishing Flutter Apps

June 02, 2026 • 1 min read

One codebase ships to both stores. You build a signed Android App Bundle and an iOS archive.

Android

flutter build appbundle   // produces app-release.aab

Configure signing in android/key.properties and build.gradle, then upload the .aab to the Play Console.

iOS

flutter build ipa   // then upload via Xcode / Transporter

Open ios/Runner.xcworkspace in Xcode for signing, then archive and submit through App Store Connect.

  • Set app name, icon (flutter_launcher_icons) and version in pubspec.yaml.
  • Test release builds on real devices before submitting.
Common mistake: Debug builds are slower and larger. Always test and ship the release build.

Summary

Build a signed .aab for Play and an .ipa for the App Store from the same Flutter project, then submit through each store.
