I use the awesome_notifications plugin in my Flutter app. In debug mode everything runs fine, but in production the app crashes at launch.

So I did bunch of testing and finally found out that in production, shrinkResources and minifyEnabled is set to true which is causing an error with the Shared Preferences giving the following error:

E/flutter ( 3523): [ERROR:flutter/runtime/dart_vm_initializer.cc(41)] Unhandled Exception: PlatformException(SHARED_PREFERENCES_NOT_AVAILABLE, class F3.b isn't parameterized, sharedPreferences.get, null)

As R8 code shrinking only happens in release build, I wasn’t catching any errors in debug mode. So I disabled code shrinking and the app worked just fine in production.

So I want to know if there are any proguard rules to prevent Shared Preferences from getting code shrinked and avoid this issue while enabling shrinkResources and minifyEnabled.
