createDataChannel method
The createDataChannel()
method of the RTCPeerConnection interface
creates a new channel linked with the remote peer, over which any kind of
data may be transmitted.
This can be useful for back-channel content, such as images, file
transfer, text chat, game update packets, and so forth.
If the new data channel is the first one added to the connection,
renegotiation is started by delivering a
RTCPeerConnection.negotiationneeded_event
event.
Implementation
external RTCDataChannel createDataChannel(
String label, [
RTCDataChannelInit dataChannelDict,
]);
