text-indent natively in Flutter can be done like so:

TextSpan(
  children: [
    WidgetSpan(child: SizedBox(width: 40.0)),
    TextSpan(text: 'lorem impsum...'),
  ],
)

How would I do this in customRender and return the parsedChild instead of the text? I tried this code but the indent just gets ignored. Using context.tree.element?.text is not an option because then it ignores other styling

(Note, the element?.styles is an extension from flutter_widget_from_html)

'p': (context, parsedChild) {
  if (context.tree.element?.styles
          .map((style) => style.property)
          .contains('text-indent') ??
      false) {
    // final style = context.tree.element?.styles
    //     .where((style) => style.property == 'text-indent')
    //     .first;
    // print(style?.value?.span);
    return TextSpan(
      children: [
        const WidgetSpan(child: SizedBox(width: 40.0)),
        WidgetSpan(child: parsedChild),
      ],
    );
  }
}

Same question, is there a solution?

I added limited support for the css attribute in my fork of this repo, you can look at it if you want

I think we can do based support (with a fixed value) fairly easily, but the percentage-bases support will already be tricky to implement in Flutter.

Please support this property!

With the new Width class, I think this has become more feasible. I'll look into getting this added

Please, implement support of this property! It is very needed! 🙏♥️🦔
