I am using below code in listening to the changes in firebase

         if (val['t'] == "ans") {
            assert(isInitiator);
            _peerCon.setRemoteDescription(
              RTCSessionDescription(
                val['sdp'],
                val['tp'],
              ),
            );
            return;
          }

One peer connection can only set one remote description.

You are trying to setRemoteDescription on a peer with an already established connection. That's why you getting this error.
