close method

@override Future close()

Prevents more data from being written to the response, and locks it entire from further editing.

Implementation

@override
Future close() async {
  if (!_isDetached) {
    if (!_isClosed) {
      if (!isBuffered) {
        // Finalizer failures propagate, leaving the response open for the
        // error handler.
        if (_finalizing != null ||
            hasPendingFinalizers ||
            _finalizerError != null) {
          await _commitOrThrow();
        }
        try {
          _openStream();
          _flushQueued();
          // Flushes the compression trailer, if any.
          _encoderSink?.close();
          // Observe the result: an unhandled failure here (e.g. the
          // connection dropped) would otherwise terminate the server.
          rawResponse.close().catchError((Object e, StackTrace st) {
            app?.logger.warning('Failed to send response', e, st);
          });
        } catch (_) {
          // This only seems to occur on `MockHttpRequest`, but
          // this try/catch prevents a crash.
        }
      } else {
        _buffer!.lock();
      }

      _isClosed = true;
    }

    await super.close();
  }
}
