Thanks for submitting.

Currently you should be able to set custom typefaces by configuring your own DefaultTextStyle. Something like this:

  Widget build(BuildContext context) {
    final style = TextStyle(fontFamily: 'Open Sans');
    return DefaultTextStyle.merge(
      style: style,
      child: ZefyrEditor(/* ... */),
    );
  }
