I'm working on an iOS [Flutter] application with VoIP features, using CallKit to handle incoming calls. Currently, when the device is locked and the user accepts an incoming call, the system UI is triggered, and the user can tap on the app icon to return to my app. This works fine.
However, I would like to implement a feature where, when the user answers the call from the lock screen, they can answer directly on the lock screen itself, instead of being redirected to the app by tapping on the logo.
Specifically, I want to ensure the audio call is conducted solely on the native lock screen, without redirecting the user to the app.
Has anyone encountered this issue or know how to achieve this behavior using CallKit in a Flutter iOS app?
