magento : render external html using magento rendering engine

Tag : magento , By : zdyne
Date : March 29 2020, 07:55 AM
I wish this helpful for you I can't speak to Drupal specifically, but since you asked generically about another CMS, I'll answer to that. Since Magento pages are built out in a modular way, you can absolutely replace chunks of the page with ones generated elsewhere. The general approach would be something like this:
Identify a block that you want to generate in the other CMS Use Magento's layout files to remove the old block and render a new block that you specify Create your block and pass any necessary parameters into it Have your block's _toHtml method make a call to the other CMS for content

Magento: Flush widget from block / fullpage cache if widget parameters change

Hope this helps EE Full Page Cache and Widget Instances Caching (no rewrites, unlimited cache life time) Overview
The first step is to create the frontend widget itself, but providing some additional info the full page cache can use.

What are the benefits of explicitly rendering reCAPTCHA widget as opposed to automatically rendering?

Tag : development , By : Antony Briggs

wish help you to fix your issue There are some things that Google allows you to do when you load it manually, like setting the language. This I believe is not the case in automatic rendering. Also, based on performance aspects, a site may not want to load the captcha automatically and want the control with itself on when to load it.

How to prevent rendering of a given widget when some other widget is on top of it in flutter?

Tag : list , By : CrookedNumber

wish of those help I managed to accomplish this using ShaderMask. The idea is that i calculate where is the header in my list item and mask this part out.
The crucial part of the list widget is this:
  Widget build(BuildContext context) => ListView.builder(
      padding: _padding, itemCount: _sectionCount, itemBuilder: _sectionHeader);

  StickyHeader _sectionHeader(BuildContext context, int sectionIndex) {
    final GlobalKey eventListHeaderKey = GlobalKey();
    final GlobalKey shaderMaskKey = GlobalKey();
    final AppStyle appStyle = AppStyle.of(context);

    return StickyHeader(
        header: Container(
            key: eventListHeaderKey,
            child: _sectionHeaderBuilder(context, sectionIndex)),
        content: ShaderMask(
            key: shaderMaskKey,
            shaderCallback: (Rect rect) =>
                _listShader(appStyle, eventListHeaderKey, shaderMaskKey, rect),
            blendMode: BlendMode.dstIn,
            child: Container(
                child: ListView.builder(
                    physics: const NeverScrollableScrollPhysics(),
                    shrinkWrap: true,
                    itemCount: _sectionElementsCountHandler(sectionIndex),
                    itemBuilder: (BuildContext context, int index) =>
                        _elementBuilder(context, sectionIndex, index)))));

  Shader _listShader(AppStyle appStyle, GlobalKey listHeaderKey,
      GlobalKey shaderMaskKey, Rect rect) {
    final RenderBox listHeaderRenderBox =
    final Offset offset = listHeaderRenderBox.localToGlobal(Offset.zero);

    final RenderBox shaderMaskRenderBox =
    final Offset offset2 = shaderMaskRenderBox.globalToLocal(offset);

    return LinearGradient(
        begin: Alignment.topCenter,
        end: Alignment.bottomCenter,
        stops: <double>[
          (rect.top + offset2.dy) / rect.height,
          (rect.top + offset2.dy) / rect.height,
        colors: <Color>[
        ]).createShader(Rect.fromLTWH(0, 0, rect.width, rect.height));
