This guide provides a step-by-step walkthrough of releasing a Flutter app to the App Store.
Before beginning the process of releasing your app, ensure that it meets Apple’s App Review Guidelines.
Register your app on App Store Connect
Manage your app’s life cycle on App Store Connect (formerly iTunes Connect). You define your app name and description, add screenshots, set pricing, and manage releases to the App Store and TestFlight.
Registering your app involves two steps: registering a unique Bundle ID, and creating an application record on App Store Connect.
For a detailed overview of App Store Connect, see the App Store Connect guide.
Register a Bundle ID
Every macOS application is associated with a Bundle ID, a unique identifier registered with Apple. To register a Bundle ID for your app, follow these steps:
- Open the App IDs page of your developer account.
- Click + to create a new Bundle ID.
- Enter an app name, select Explicit App ID, and enter an ID.
- Select the services your app uses, then click Continue.
- On the next page, confirm the details and click Register to register your Bundle ID.
Create an application record on App Store Connect
Register your app on App Store Connect:
- Open App Store Connect in your browser.
- On the App Store Connect landing page, click My Apps.
- Click + in the top-left corner of the My Apps page, then select New App.
- Fill in your app details in the form that appears. In the Platforms section, ensure that iOS is checked. Since Flutter does not currently support tvOS, leave that checkbox unchecked. Click Create.
- Navigate to the application details for your app and select App Information from the sidebar.
- In the General Information section, select the Bundle ID you registered in the preceding step.
For a detailed overview, see Add an app to your account.
Review Xcode project settings
This step covers reviewing the most important settings in the Xcode workspace. For detailed procedures and descriptions, see Prepare for app distribution.
Navigate to your target’s settings in Xcode:
- In Xcode, open
Runner.xcworkspacein your app’s
- To view your app’s settings, select the Runner project in the Xcode project navigator. Then, in the main view sidebar, select the Runner target.
- Select the General tab.
Verify the most important settings.
In the Identity section:
- The app category under which your app will be listed on the Mac App Store. This cannot be none.
- The App ID you registered on App Store Connect.
In the Deployment info section:
- The minimum macOS version that your app supports. Flutter supports macOS 10.11 and later.
In the Signing & Capabilities section:
Automatically manage signing
- Whether Xcode should automatically manage app signing
and provisioning. This is set
trueby default, which should be sufficient for most apps. For more complex scenarios, see the Code Signing Guide.
- Select the team associated with your registered Apple Developer account. If required, select Add Account…, then update this setting.
The General tab of your project settings should resemble the following:

Updating the app’s version number
The default version number of the app is
To update it, navigate to the
and update the following line:
The version number is three numbers separated by dots,
1.0.0 in the example above, followed by an optional
build number such as
1 in the example above, separated by a
Both the version and the build number may be overridden in Flutter’s
build by specifying

on the Apple Developer’s site.
Add an app icon
When a new Flutter app is created, a placeholder icon set is created. This step covers replacing these placeholder icons with your app’s icons:
- Review the macOS App Icon guidelines.
- In the Xcode project navigator, select
Runnerfolder. Update the placeholder icons with your own app icons.
- Verify the icon has been replaced by running your app using
flutter run -d macos.
Create a build archive with Xcode
This step covers creating a build archive and uploading your build to App Store Connect using Xcode.
During development, you’ve been building, debugging, and testing with debug builds. When you’re ready to ship your app to users on the App Store or TestFlight, you need to prepare a release build. At this point, you might consider obfuscating your Dart code to make it more difficult to reverse engineer. Obfuscating your code involves adding a couple flags to your build command.
In Xcode, configure the app version and build:
- In Xcode, open
Runner.xcworkspacein your app’s
- Select Runner in the Xcode project navigator, then select the Runner target in the settings view sidebar.
- In the Identity section, update the Version to the user-facing version number you wish to publish.
- In the Identity section, update the Build identifier to a unique build number used to track this build on App Store Connect. Each upload requires a unique build number.
Finally, create a build archive and upload it to App Store Connect:
Open Xcode and select Product > Archive. Run
flutter build macosto produce a build archive.
Click the Validate App button. If any issues are reported, address them and produce another build. You can reuse the same build ID until you upload an archive.
After the archive has been successfully validated, click Distribute App. You can follow the status of your build in the Activities tab of your app’s details page on App Store Connect.
You should receive an email within 30 minutes notifying you that your build has been validated and is available to release to testers on TestFlight. At this point you can choose whether to release on TestFlight, or go ahead and release your app to the App Store.
For more details, see Upload an app to App Store Connect.
Create a build archive with Codemagic CLI tools
This step covers creating a build archive and uploading your build to App Store Connect using Flutter build commands and Codemagic CLI Tools executed in a terminal in the Flutter project directory.
Install the Codemagic CLI tools:
pip3 install codemagic-cli-tools
You’ll need to generate an App Store Connect API Key with App Manager access to automate operations with App Store Connect. To make subsequent commands more concise, set the following environment variables from the new key: issuer id, key id, and API key file.
export APP_STORE_CONNECT_ISSUER_ID=aaaaaaaa-bbbb-cccc-dddd-eeeeeeeeeeee export APP_STORE_CONNECT_KEY_IDENTIFIER=ABC1234567 export APP_STORE_CONNECT_PRIVATE_KEY=`cat /path/to/api/key/AuthKey_XXXYYYZZZ.p8`
You need to export or create a Mac App Distribution and a Mac Installer Distribution certificate to perform code signing and package a build archive.
If you have existing certificates, you can export the private keys by executing the following command for each certificate:
openssl pkcs12 -in <certificate_name>.p12 -nodes -nocerts | openssl rsa -out cert_key
Or you can create a new private key by executing the following command:
ssh-keygen -t rsa -b 2048 -m PEM -f cert_key -q -N ""
Later, you can have CLI tools automatically create a new Mac App Distribution and Mac Installer Distribution certificate. You can use the same private key for each new certificate.
Fetch the code signing files from App Store Connect:
app-store-connect fetch-signing-files YOUR.APP.BUNDLE_ID \ --platform MAC_OS \ --type MAC_APP_STORE \ --certificate-key=@file:/path/to/cert_key \ --create
cert_keyis either your exported Mac App Distribution certificate private key or a new private key which automatically generates a new certificate.
If you do not have a Mac Installer Distribution certificate, you can create a new certificate by executing the following:
app-store-connect create-certificate \ --type MAC_INSTALLER_DISTRIBUTION \ --certificate-key=@file:/path/to/cert_key \ --save
cert_keyof the private key you created earlier.
Fetch the Mac Installer Distribution certificates:
app-store-connect list-certificates \ --type MAC_INSTALLER_DISTRIBUTION \ --certificate-key=@file:/path/to/cert_key \ --save
Set up a new temporary keychain to be used for code signing:
Now add the fetched certificates to your keychain:
Update the Xcode project settings to use fetched code signing profiles:
Install Flutter dependencies:
flutter packages pub get
Install CocoaPods dependencies:
find . -name "Podfile" -execdir pod install \;
Enable the Flutter macOS option:
flutter config --enable-macos-desktop
Build the Flutter macOS project:
flutter build macos --release
Package the app:
APP_NAME=$(find $(pwd) -name "*.app") PACKAGE_NAME=$(basename "$APP_NAME" .app).pkg xcrun productbuild --component "$APP_NAME" /Applications/ unsigned.pkg INSTALLER_CERT_NAME=$(keychain list-certificates \ | jq '. | select(.common_name | contains("Mac Developer Installer")) | .common_name' \ | xargs) xcrun productsign --sign "$INSTALLER_CERT_NAME" unsigned.pkg "$PACKAGE_NAME" rm -f unsigned.pkg
Publish the packaged app to App Store Connect:
app-store-connect publish \ --path "$PACKAGE_NAME"
As mentioned earlier, don’t forget to set your login keychain as the default to avoid authentication issues with apps on your machine:
Distribute to registered devices
Release your app to the App Store
When you’re ready to release your app to the world, follow these steps to submit your app for review and release to the App Store:
- Select Pricing and Availability from the sidebar of your app’s application details page on App Store Connect and complete the required information.
- Select the status from the sidebar. If this is the first release of this app, its status is 1.0 Prepare for Submission. Complete all required fields.
- Click Submit for Review.
Apple notifies you when their app review process is complete. Your app is released according to the instructions you specified in the Version Release section.
