Usage

Zeta offers flexibility in theming through its ZetaProvider widget. Here's a breakdown of its features:

Setting the Initial Theme Mode

Zeta allows you to specify an initial theme mode for your app, which can be one of the following:

• ThemeMode.system: Adheres to the system's theme.
• ThemeMode.light: Uses the light theme mode.
• ThemeMode.dark: Uses the dark theme mode.

By default, the theme mode is set to ThemeMode.system.

initialThemeMode: ThemeMode.light

Providing Initial Theme Data

You can provide the initial theme data for the app which contains all the theming information. If you don't specify one, it will default to a basic instance of ZetaThemeData.

initialThemeData: ZetaThemeData()

Setting the Initial Contrast

Zeta also lets you define the initial contrast setting for your app. By default, it's set to ZetaContrast.aa.

initialContrast: ZetaContrast.aa

Building Your App with Zeta Theming

The builder function is used to construct the widget tree with the provided theming information. This function is expected to receive a BuildContext, ZetaThemeData, and ThemeMode as arguments, and it should return a Widget.

builder: (context, themeData, themeMode) {
  // Your app's widget tree here
}

Constructing the ZetaProvider

To tie everything together, use the ZetaProvider constructor. The builder argument is mandatory, while the others are optional but allow you to set initial values:

 @override
  Widget build(BuildContext context) {
    return ZetaProvider(
      builder: (context, themeData, themeMode) {
        final dark = themeData.colorsDark.toScheme();
        final light = themeData.colorsLight.toScheme();
        return MaterialApp.router(
          routerConfig: router,
          themeMode: themeMode,
          theme: ThemeData(
            fontFamily: themeData.fontFamily,
            scaffoldBackgroundColor: light.background,
            colorScheme: light,
          ),
          darkTheme: ThemeData(
            fontFamily: themeData.fontFamily,
            scaffoldBackgroundColor: dark.background,
            colorScheme: dark,
          ),
        );
      },
    );
  }

With these configurations, Zeta makes it easy to achieve consistent theming throughout your Flutter application.
