close method

@override Future<void> close([ CloseStatus status = CloseStatus.normal ])

Closes the connection, sending status (CloseStatus.normal by default) to the other side. The future completes when the connection is closed.

Implementation

@override
Future<void> close([CloseStatus status = CloseStatus.normal]) {
  _local ??= status;
  if (!_incoming.hasListener) {
    // Nobody reads yet: read on, so that the other side's answer (its
    // close frame) is seen and the close completes, as dart:io's drain
    // would; a later listener gets the end of the stream.
    _closedUnheard = true;
    _read();
  }
  if (_guard?.dropped ?? false) {
    return Future.value();
  }
  return _socket.close(status.code, status.reason);
}
