Cannot change ThemeData

[Atulin]

My MyApp class

class MyApp extends StatelessWidget {
  // This widget is the root of your application.
  @override
  Widget build(BuildContext context) {
    return new DynamicTheme(
      defaultBrightness: Brightness.light,
      data: (brightness) => new ThemeData(
        brightness: brightness,
      ),
      themedWidgetBuilder: (context, theme) {
        return new MaterialApp(
          title: 'Omnibus',
          theme: theme,
          home: new SplashScreen(
            title: 'Omnibus',
          ),
        );
      },
    );
  }
}

How I'm changing the theme:

new IconButton(
  icon: new Icon(Icons.palette),
  color: Color.fromARGB(255, 15, 84, 108),
  onPressed: (){
    DynamicTheme.of(context).setBrightness(Brightness.dark);    
    DynamicTheme.of(context).setThemeData(new ThemeData(
      primaryColor: Color.fromARGB(255, 15, 84, 108),
      accentColor: Colors.yellow,
    ));
  }
),

The brightness is being changed properly, however the primary color or the accent color are not.

The setBrightness is just a convenient method because it's the most common use case. Try this:

                  DynamicTheme.of(context).setThemeData(new ThemeData(
                    brightness: Brightness.dark,
                    primaryColor: Color.fromARGB(255, 15, 84, 108),
                    accentColor: Colors.yellow,
                  ));

Works perfectly, thank you!
