Flutter android flavors generate apk

Question

I am trying to set up Android flavors with flutter.

I have two entry points.

lib/main_prod.dart
lib/main_dev.dart

I have also added the following to my gradle file

flavorDimensions "version"
productFlavors {
    prod {
        dimension "version"
        applicationIdSuffix ".prod"
    }
    dev {
        dimension "version"
        applicationIdSuffix ".dev"
        versionNameSuffix " Dev"
    }
}

Now I am trying to generate two separate apk which I can use to publish to the Google Play Store.

I go on Android Studio and try generate these.

However I get this error.

Android Studio is still trying to look for the main.dart file, however, for my two flavors they are main_prod.dart and main_dev.dart. How do I tell Android Studio to look for the approperiate main file depending on the flavor im trying to get the apk file for.

Solution

To build apk or appbundle(to publish to the playstore) for each flavor you can use the commands(recommended) instead of using android studio.

For prod you can use:

APK

flutter build apk --flavor prod -t lib/main_prod.dart

App Bundle

flutter build appbundle --flavor prod -t lib/main_prod.dart

and for dev

APK

flutter build apk --flavor dev -t lib/main_dev.dart

App Bundle

flutter build appbundle --flavor dev -t lib/main_dev.dart
