Deploy a Flutter app to Google Play using the Flutter workflow editor

Codemagic enables you to automatically publish your app to the internal, alpha, beta and production tracks on Google Play. To do so, you must first set up Android code signing and then configure publishing to Google Play.

This guide only applies to workflows configured with the Flutter workflow editor. If your workflow is configured with codemagic.yaml please go to Publishing to Google Play using codemagic.yaml.


You will need a service account in Google Play Console to obtain the JSON credentials file. See how to do that here. In addition, you must build the app in release mode and set up Android code signing.

Before releasing the app to Google Play, ensure that it meets Google Play’s best practices guidelines.

Note that if you haven’t published your app to Google Play yet, you must create an entry for your app in Google Play Console and manually upload the very first version of the app before you can automate publishing using Codemagic. In addition, each uploaded binary must have a different version; see how to automatically increment build version on Codemagic.

Setting up publishing to Google Play on Codemagic

Once you configure publishing to Google Play, Codemagic will automatically distribute the app to Google Play every time you build the workflow.

The very first version of the app must be added to Google Play manually. You can download the app_release.apk from the build artifacts.
  1. Navigate to the Distribution section in app settings.

  2. Click Google Play to expand the option.

  3. Upload your credentials JSON file.

  4. Select a track for publishing.

    • Internal — publish for internal testing and QA
    • Alpha — publish for testing with a small group of trusted users
    • Beta — publish for testing to a wider set of users
    • Production — release the app to production
    • Custom — release the app to a custom closed testing track
  5. If you want to publish to a custom track, enter the custom track name.

  6. If your application supports in-app updates, set the desired priority. If not, select Default.

  7. In case you want to release a staged version of your application, which reaches only a fraction of users, set Rollout fraction to a value between 0 and 1. To release to everyone, leave the value empty.

  8. If you are getting the next error: Changes cannot be sent for review automatically. Please set the query parameter changesNotSentForReview to true, mark the checkbox Do not send changes for review.

    But if the checkbox is marked and the app is sent for review automatically, you will get the error Changes are sent for review automatically. The query parameter changesNotSentForReview must not be set.

  9. If you want to publish the .apk even when one or more tests fail, mark the Publish even if tests fail checkbox.

  10. Select Enable Google Play publishing at the top of the section to enable publishing.
