[proposal] Add fontFamilyFallback property into ThemeData #109773
Description
Use case
Currently it is possible to set fontFamily globally in our theme using ThemeData, but we can't do it for fontFamilyFallback.
Proposal
Add fontFamilyFallback property into ThemeData.
ThemeData getAppTheme(Brightness brightness) {
final colors = brightness == Brightness.light ? colorsLight : colorsDark;
return ThemeData(
brightness: brightness,
fontFamily: AppFonts.roboto,
fontFamilyFallback: ----------------------> Needed property
scaffoldBackgroundColor: colors.background,
// ... more configurations.
);
}
