Customizing based on each brightness

[mohammadne]

I want to define accentColor , scaffoldBackgroundColor , for each brightness.
also I have some textTheme which I want to define for each brightness.
but if I write scaffoldBackgroundColor like bellow , it doesn't work:

ThemeData(
                brightness: brightness,
                scaffoldBackgroundColor:
                    Theme.of(context).brightness == Brightness.light
                        ? Colors.black
                        : Colors.white,
               ...
                fontFamily: 'IranYekan',
                textTheme: TextTheme(
                  headline: TextStyle(
                      color: Colors.black54, fontWeight: FontWeight.w700),
                  title: TextStyle(
                      color: Colors.black54, fontWeight: FontWeight.w700),
                  subtitle: TextStyle(fontWeight: FontWeight.w700),
                  body2: TextStyle(fontWeight: FontWeight.w300),
                  display1: TextStyle(fontWeight: FontWeight.w700),
                  display2: TextStyle(fontWeight: FontWeight.w700),
                  display3: TextStyle(fontWeight: FontWeight.w700),
                  display4: TextStyle(fontWeight: FontWeight.w700),
                ),
              ...
              )

it seems that this themeData execute only once,
if I use DynamicTheme.of(context).setThemeData(Theme.of(context).copyWith());
also it raised an error
because I want to save last theme which user select and its accentColor and ... .
also I tried to define darkTheme in materialApp but it doesn't work.
if we had possibility to define brightness features , it was so good.
but is it possible?

Hey, sorry - I'm not quite sure what the issue is.

DynamicTheme.of(context).setThemeData(Theme.of(context).copyWith());

should work just fine.
Also, change Theme.of(context).brightness to brightness as the builder supplies a brightness.

This package automatically saves only the brightness of the shared preferences.
