render method

@override dynamic render()

Renders the elements of this component.

Accepted return types:

• web UINode and UIElement.
• DIVElement, DOMNode, AsDOMElement and AsDOMNode.
• Future.
• UIAsyncContent.
• String, parsed as HTML.
• Map (rendered as JSON).
• List with previous types (recursively).
• Function that returns any previous type. Including Function<Future>, allowing async functions.

Implementation

@override
dynamic render() {
  _asyncContentRenderCount++;

  var properties = renderProperties();

  if ((!cacheRenderAsync && _asyncContentRenderCount > 1) ||
      !UIAsyncContent.isValid(_asyncContent, properties)) {
    _asyncContent = UIAsyncContent.provider(
      () => _renderAsync!(renderProperties()),
      loadingContent,
      errorContent: errorContent,
      refreshInterval: refreshInterval,
      properties: properties,
    );
    _asyncContent!.onLoadContent.listen((content) {
      onLoadAsyncContent.add(content);
      onChange.add(content);
    });
    _asyncContentRenderCount = 0;
  }

  return _asyncContent;
