Show contacts in some order

[NoxiousAmusedFrog]

Hello! Greate job!
Is some way add parameter for setting order (ASC/DESC) of contacts in Flutter?
Now I can do it only modifing plugin code:
cursor = contentResolver.query(
ContactsContract.Data.CONTENT_URI,
null,
null,
null,
// ContactsContract.Contacts.SORT_KEY_PRIMARY + " ASC")
"upper("+ContactsContract.CommonDataKinds.Phone.DISPLAY_NAME + ") ASC")
