label property

String get label

The read-only RTCDataChannel property label returns a string containing a name describing the data channel. These labels are not required to be unique.

You may use the label as you wish; you could use it to identify all the channels that are being used for the same purpose, by giving them all the same name. Or you could give each channel a unique label for tracking purposes. It's entirely up to the design decisions made when building your site or app.

A unique ID can be found in the RTCDataChannel.id property.

Note: A data channel's label is set when the channel is created by calling RTCPeerConnection.createDataChannel. It cannot be changed after that.

Implementation

external String get label;
