Use case

Flutter apps need to use a system font for displaying a plain text. I guess I can use FontLoader to use a default system font on Android with a plugin but it would be really great to have this feature supported by engine.
Samsung, LG or other vendors using Android has a feature that users can change a system font in settings but this default font setting is ignored in flutter apps because it uses a built-in font provided by flutter engine. Users using a different font as their default font feel awkward as their setting isn't applied on their Android devices.
