protocol property
String
get
protocol
The read-only RTCDataChannel
property
protocol
returns a string containing the
name of the subprotocol in use. If no protocol was specified when the data
channel was
created, then this property's value is the empty string (""
).
Note: The permitted values of this property are defined by the website or app using the data channel.
The ability for each channel to have a defined subprotocol lets your app, for example, use JSON objects as messages on one channel while another channel is plaintext and another is raw binary or even some other format.
Implementation
external String get protocol;
