 You can build an apk by running the following command from the root of the repository:
 ```console
-flutter build apk --release --flavor $FLAVOR --dart-define cameraPreviewAspectRatio=2/3 -t lib/main_$FLAVOR.dart
+flutter build apk --release --flavor $FLAVOR --dart-define cameraPreviewAspectRatio=240/320 -t lib/main_$FLAVOR.dart
 ```
 Just replace `$FLAVOR` with `dev` or `prod`.
