I have a flutter application that hosts native iOS UIViewController in flutter, but I am not showing it to user just keeping it active (in the back of stack in the screen)
this screen has special SDK that can read cards (loyalty card etc.) so I we do not know when person can make card reading.
I need to make a call from native iOS side to flutter side with some information sent. I know we can make from flutter side call with channels and get information from native side. But how about getting from native iOS side at any time to flutter side?
Can someone help please.
