iOS stops working when the flutter_background_service is started #10
Description
twilio_voice_flutter for iOS stops working when flutter_background_service is started. If the flutter_background_service is not started, the voice call is going through, but when the background service is activated then it stop working.
Basically, It does not retain self variables in the iOS class and delegates, but when I tried to trace the phone number in hangUp method the self.callTo is retained.
