[FEATURE] add support for specifying font package

[AristideVB]

Describe your feature request

Currently if our fonts are located inside a local package they cannot be retrieved inside flutter_html Style() like they can in a regular Flutter TextStyle() :

TextStyle(
    package: 'ui_package', 
    fontFamily: 'Circular Air Pro',
    color: Colors.green,
  );

It would look something like this :

Html(
        data: mockData,
        style: {
          'body': Style(
            package: 'ui_package',            // specify font package here 
            fontFamily: 'Circular Air Pro',
            margin: EdgeInsets.zero,
            padding: EdgeInsets.zero,
          ),
        },
      ),

Additional request

It would also be nice to be able to use TextStyle( ) rather than Style( )

This would be helpful for GoogleFonts as well. At the moment, we can't really set the style (e.g. fontWeight) for a Google font inside the Html widget, can we? Additionally, if I set a Google font as standard font in the TextTheme of the app, some letters look really strange (see screenshot). This is just on Android! On iOS everything looks good. Is there a way to fix this?

Thanks for the feedback @AristideVB! I agree, font package support definitely seems like a valid use case. I'll look into what it will take to get that added. As for using TextStyle instead of Style, have you looked into the Style.fromTextStyle constructor?

@hschk That is certainly strange. I've used Google Fonts myself and haven't seen the issue. Do you have a reproducible example?

I'm also looking for global customization of font family from GoogleFonts for Html widget. Would love to use it.

It's possible to use Google Fonts like this
