Is there any way to create call recording app in flutter?

Question

So, I have tried to develop an application for call recording :

• By using flutter_sound to record a call and I am detecting call state using phone_state_i but succeeded to record the call with the voice of MICROPHONE only cannot record the voice of other people (INCOMING voice).
• Then I tried to record calls using android through flutter native integration but unable to achieve. So even here I got succeeded to record only the voice of a microphone.

I guess I am unable to get the concept of VOICE_DOWNLINK and VOICE_UPLINK. And got to know that VOICE_CALL is deprecated. So, I am badly stuck and need some expert advice.

Google has removed this functionality as of 2022. https://web.archive.org/web/20230930121122/https://www.androidpolice.com/google-ends-call-recording-apps-accessibility-services/
