close method

@override Future close()

Close the target consumer.

NOTE: Writes to the IOSink may be buffered, and may not be flushed by a call to close(). To flush all buffered writes, call flush() before calling close().

Implementation

@override
Future close() async {
  final web.ResponseInit responseInit = web.ResponseInit(
    status: statusCode,
    statusText: reasonPhrase,
  );

  final web.Response response = web.Response(
    () {
      if (_content is String) {
        try {
          return _content.toJS;
        } catch (e) {
          return json.encode(json.decode(_content)).toJS;
        }
      } else if (_content is num) {
        return _content.toJS;
      } else if (_content is Map || _content is List) {
        return json.encode(_content).toJS;
      } else {
        return (_content ?? "").toString().toJS;
      }
    }(),
    responseInit,
  );
  {
    _httpHeaders.forEach((key, values) {
      response.headers.set(key, values.join("; "));
    });
    final contentType = _httpHeaders.contentType;
    if (contentType != null) {
      response.headers.set("content-type", contentType.value);
    }
  }
  return response;
