Hey,
I can build a voice calling app using flutter.
Can we discuss the project in detail ? Lets have a quick chat so we could discuss all the details and features easily for much better understanding.
I've been a full stack mobile application developer working for the last 7 years and have successfully worked on many mobile applications for android and ios and have recently worked on several mobile applications using flutter.

Looking forward for your valuable response on chat board, thanks.
Best Regards
Shariq Imam
