[QUESTION] migrate customRender to customRender on flutter_html v3

[evaisse]

I have an old implementation of customRender which is below

        "li": (RenderContext context, widget) {
          context.style.markerContent = null; // Remove bullet point for list cause list-style: none is not supported
        },
        "center": (RenderContext context, widget) {
          context.style.textAlign = TextAlign.center;
        }

Basically, this code just alter the style passed to generated widget regarding is tag name. But trying to migrate to flutter_html:^3.0, I can find any way to do the same. How would you migrate old customRender parameters to the new customRenders in this case ?

Haven't tested it but this should give you the general idea.

return Html(
	data: data,
	tagsList: Html.tags..addAll(['li']),
	customRenders:
	{
		liMatcher(): CustomRender.widget(widget: (RenderContext context, buildChildren)
		{
                        context.style.markerContent = null;
			return Text('li replacement');
		}),
	}
);

CustomRenderMatcher liMatcher() => (context) => context.tree.element?.localName == 'li';
