I am new to Flutter and I want to implement 1/1 call functionality for my users. What is the best way to make calls and send call invitation.

I watched a tutorial on YouTube about WhatsApp clone that used Heroku as server. But since Heroku is no longer free. Are there any alternatives to Heroku and why do we even need a server?

for the agora audio calling feature, you can use FCM (Firebase Cloud Messaging) or Sockets to send the invitation .

I personally prefer custom sockets to implement the calling functionality. and I've used the sockets using socket.io
