I have created and apply custom theme for my flutter app and it correctly previewed in my emulator. But when I check it from my physical device it does not apply any theme effect.
Text('Hello World!' ,style: Theme.of(context).textTheme.headline1),
Above code headline1 I have customized like,
headline1: GoogleFonts.roboto(
color: Colors.black38,
fontSize: 22,
fontWeight: FontWeight.w700,
height: 1,
),
In the physical device it use default headline1.
I want to apply my custom theme to physical device as well
