<sub> and <sup> tag aren't working in the android emulator

[KaMoKuMo]

When I tried to emulate the example app on an Pixel 2, using Android 9.0, using AndroidStudio it would neither display the "< sub>2< /sub>" tag at the logs nor the "< sup>2< /sup >" tag at the following x.

It should at least display them, though incorrectly. Please post the configuration of your Html widget and the version of flutter_html you are using.

I'm not sure what you mean by Html widget config. I copy-pasted your example main.dart into a new flutter project (main.dart) and wrote: ^0.10.4 into the pubspec.yaml

    child: SingleChildScrollView(
      child: Html(
        data: ..., 
        //Optional parameters:
        padding: EdgeInsets.all(8.0),
        linkStyle: const TextStyle(
          color: Colors.redAccent,
          decorationColor: Colors.redAccent,
          decoration: TextDecoration.underline,
        ),
        onLinkTap: (url) {
          print("Opening $url...");
        },
        onImageTap: (src) {
          print(src);
        },
        //Must have useRichText set to false for this to work
        customRender: (node, children) {
          if (node is dom.Element) {
            switch (node.localName) {
              case "custom_tag":
                return Column(children: children);
            }
          }
          return null;
        },
        customTextAlign: (dom.Node node) {
          if (node is dom.Element) {
            switch (node.localName) {
              case "p":
                return TextAlign.justify;
            }
          }
          return null;
        },
        customTextStyle: (dom.Node node, TextStyle baseStyle) {
          if (node is dom.Element) {
            switch (node.localName) {
              case "p":
                return baseStyle.merge(TextStyle(height: 2, fontSize: 20));
            }
          }
          return baseStyle;
        },
      ),
    ),

Do you need any other information?

By setting:
useRichtText = false;
the problem is circumvented.
