Is it possible to implement call overlay in React Native / Flutter?

Question

React Native

I don’t know what it’s called correctly, call overlay or something else, but the question is, is it possible to implement a call, as is done in Telegram / Whatsapp, etc., including when the screen is off?

Answer 1

when I was doing such a project and the result was, https://github.com/tariq86/rn-sip-app used this repository as a basis. react-native-callkit is for displaying the call. the project was brought to the state of running through time. it was clear that the code itself is old and it is better to write this project natively on androyd and ios. As for flutter, we haven't been able to try our hand at this direction yet.
