push method
Sends the client a text (String) or binary (List<int>) message,
as the server would. Throws a StateError once the connection is
closed.
Implementation
void push(Object message) {
if (isClosed) {
throw StateError('The connection is closed');
}
_incoming.add(
message is List<int> && message is! Uint8List
? Uint8List.fromList(message)
: message,
);
}
