Android versioning in flutter using codemagic

[Navaneet00]

How to update the version code and version name of the app?
When codemagic updates version code and version name using the latest version from google play store or app store and incrementing it... I want to assign this version in the app directly.
I want to show version name in my app in the settings page. Also can u please suggest other ways to set the latest version of app using codemagic?

hello @Navaneet00,
There are several approaches you can use for build versioning on Codemagic. One of the easiest ways to increment the application version on every build is by using the built-in environment variables that Codemagic exports during the build, such as the PROJECT_BUILD_NUMBER variable. This variable represents the current build number of your project and is automatically incremented with each new build of your app.

If you are building a Flutter app, your build command in your yaml file would look like this;

- name: Build AAB with Flutter
  script: |
     flutter build appbundle --release \
     --build-name=1.0.$PROJECT_BUILD_NUMBER \
     --build-number=$PROJECT_BUILD_NUMBER

If you want to use the latest version from the Google Play Store, your build command would look like this:

- name: Build AAB with Flutter
  script: |
    LATEST_GOOGLE_PLAY_BUILD_NUMBER=$(($(google-play get-latest-build-number --package-name "$PACKAGE_NAME" --tracks="$GOOGLE_PLAY_TRACK") + 1))
    if [ -z $LATEST_GOOGLE_PLAY_BUILD_NUMBER ]; then
      UPDATED_BUILD_NUMBER=$BUILD_NUMBER
    else
      UPDATED_BUILD_NUMBER=$(($LATEST_GOOGLE_PLAY_BUILD_NUMBER + 1))
    fi
    flutter build appbundle --release \
      --build-name=1.0.$UPDATED_BUILD_NUMBER \
      --build-number=$UPDATED_BUILD_NUMBER

You will also need to make changes in the build.gradle file so that the code dynamically adjusts the versionCode and versionName based on the latest build number from Google Play or the environment variable BUILD_NUMBER

android {
    def latestGooglePlayBuildNumber = Integer.valueOf(System.env.LATEST_GOOGLE_PLAY_BUILD_NUMBER ?: System.env.BUILD_NUMBER ?: 0)

    defaultConfig {
        // TODO: Specify your own unique Application ID (https://developer.android.com/studio/build/application-id.html).
        applicationId "io.codemagic.test”
        // You can update the following values to match your application needs.
        // For more information, see: https://docs.flutter.dev/deployment/android#reviewing-the-gradle-build-configuration.
        minSdkVersion flutter.minSdkVersion
        targetSdkVersion flutter.targetSdkVersion
        versionCode latestGooglePlayBuildNumber + 1
        versionName "1.0." + String.valueOf(latestGooglePlayBuildNumber + 1)
    }
}

But please check this documentation for more information regarding automatic versioning.
You can also check our example templates that you can also reuse.

If you encounter any road blocks, let me know, share the build ID, and I'll assist you through the process
