Thanks @daohoangson. Seems like upgrading the plugin version worked like charm. But does the plugin currently support alphabet lists?
Numeric lists, Roman numeric lists, and bullet-point lists are working fine.

No, not yet. I have created a new issue for this daohoangson/flutter_widget_from_html#90, subscribe to that one if you want to get notified when it's released.
