Use themeMode in SharezoneMaterialApp.

[Jonas-Sander]

From themeMode docs:

Determines which theme will be used by the application if both [theme] and [darkTheme] are provided.

If set to [ThemeMode.system], the choice of which theme to use will be based on the user's system preferences. If the [MediaQuery.platformBrightnessOf] is [Brightness.light], [theme] will be used. If it is [Brightness.dark], [darkTheme] will be used (unless it is null, in which case [theme] will be used.

If set to [ThemeMode.light] the [theme] will always be used, regardless of the user's system preference.

If set to [ThemeMode.dark] the [darkTheme] will be used regardless of the user's system preference. If [darkTheme] is null then it will fallback to using [theme].

The default value is [ThemeMode.system].

Would it make more sense to don't have a default value? Therefore, the analyzer would show a warning when add a new value for ThemeBrithness

Good catch! Yeah of course, was maybe left over from the standard template.
