trySendBytes method
Sends binary data to the peer, unless connection is already
closed (either through close or by the peer). Returns false if
connection is known to be closed, otherwise true.
Data sent through sendBytes will be silently discarded if the peer is disconnected but the disconnect has not yet been detected.
Implementation
@override
bool trySendBytes(Uint8List b) {
if (isClosed) return false;
sendFrame(WebSocketOpcode.binary, b);
return true;
}
