Fixed scheduleNotification crashing the app in release mode.

The app wasn't correctly configured for release mode as described in the flutter_local_notifications package readme: https://github.com/MaikuB/flutter_local_notifications/blob/master/flutter_local_notifications/README.md#release-build-configuration

The release mode is now configured according to the steps in this article: https://medium.com/@swav.kulinski/flutter-and-android-obfuscation-8768ac544421
