It sounds like a missing Proguard configuration. It's necessary to add a specific config to keep the Easy AR SDK files in the build app. Please ensure, that you have something similar to the config in the example project.
Let me know if that fixes your issue.

I am encountering an issue with the plugin where it fails to function properly specifically in the production environment. Despite successful testing in development environments, the plugin exhibits unexpected behavior or outright fails to execute its intended functionality when deployed to production on google platform. In IOS platform all is ok. I purchased the Easy AR Sense License Key and placed my code in AndroidManifest.xml:
<meta-data android:name="com.miquido.ar_quido.API_KEY" android:value="oungqKb6......" />
The error I can find by compiling the app bundle with the following commands in Android Studio terminal is:
flutter clean flutter pub get flutter build appbundle flutter run --release
