close method

@override Future<void> close()

Closes the socket. Must complete even if it was never open.

Implementation

@override
Future<void> close() async {
  if (_closed) return;
  _closed = true;
  // Not awaited on purpose: a single-subscription controller that was never
  // listened to never completes its close future, and a transport whose
  // `ready` failed is exactly that case.
  if (!_incoming.isClosed) unawaited(_incoming.close());
}
