faces method
Every installed face, or those of family (matched without regard to
case), in the order the platform lists them. Empty where
families would be, for the same reason.
Implementation
Future<List<DVSystemFontFace>> faces({String? family}) async {
final List<DVSystemFontFace> all = (await _list()).faces;
if (family == null) return all;
final String key = family.toLowerCase();
return <DVSystemFontFace>[
for (final DVSystemFontFace face in all)
if (face.family.toLowerCase() == key) face,
];
}
