Accessing named sharedpreference from a service

Question

I'm trying to access SharedPreference from a service and getting an error which I cannot find anywhere on the net. Any help is appreciated. Thank you.

code sharedPref = getApplicationContext().getSharedPreferences("FlutterSharedPreferences",Context.MODE_PRIVATE|Context.MODE_MULTI_PROCESS);

This error appears only when accessing the SharedPreference from a service. The same line of code works fine in an activity.
