font support missing in Rich Text Parser

[SoftWyer]

The Rich Text parser is missing support for the <font /> tag and thus renders no content. The HTML parser has this support.

I've modified the parser to accept font and to also render the color if it's a HEX string. I'll see if I can arrange for a pull request, e.g.

          case "strong":
            childStyle = childStyle.merge(TextStyle(fontWeight: FontWeight.bold));
            break;
          case "font":
            Color c;
            String color = node.attributes['color'] ?? '';
            if (color.startsWith('#')) {
              // A hex color
              c = HexToColor(color);
            }
            childStyle = childStyle.merge(TextStyle(
              color: c,
            ));
            break;
          case "i":

HexToColor is a simple class to render the hex string, e.g.

class HexToColor extends Color{
  static _hexToColor(String code) {
    return int.parse(code.substring(1, 7), radix: 16) + 0xFF000000;
  }
  HexToColor(final String code) : super(_hexToColor(code));
}

In theory, font takes an 'rgb(a,b,c)' string too so that should be easy to implement. It also handles color names such as 'red' but I can't see an easy way of converting these to a Color object

It's possible that we could do something with the size argument of font too but I currently don't need that option.

We have inline style support now, which is really what your html should be using.

If support for the legacy (html 4 and lower) tag is still something you desire, please re-open this ticket. We would add it I guess.
