  const MyApp({Key? key}) : super(key: key);    
    
  @override    
  Widget build(BuildContext context) {    
    final locale = Localizations.localeOf(context);  
    return PlayXThemeBuilder(    
      builder: (xTheme) {    
        return MaterialApp(    
          title: 'Flutter Demo',    
          theme: (locale)=> xTheme.theme(locale),    
          home: const MyHomePage(),    
        );    
      },    
    );    
  }    
}    

Update App Theme

Use PlayxTheme to switch between themes. As it provides some methods that demonstrate current app theme, it's index, name and id and allow you to easily update current app theme.

    FloatingActionButton(    
        //Change App theme to the next theme in Theme Config.    
        onPressed: PlayxTheme.next,  //changes theme to next theme  
        child: Icon(Icons.next,    
        color: PlayxTheme.colorScheme.onBackground //color updates by theme.    
        ),    
      ),    

Here is a PlayxTheme methods :

supportedThemes	Get current supported themes configured in XThemeConfig.

isDeviceInDarkMode	Determines whether the device is in dark or light mode.

Customize Your Themes

To customize your themes, Create a class that extends XThemeConfig then overrides it's themes methods and provides it with all themes that your app needs.

For example:

 class AppThemeConfig extends XThemeConfig {  
  @override  
  List<XTheme> get themes => [  
        XTheme(  
            id: 'light',  
            nameBuilder: () => 'Light',  
            theme: (locale) => ThemeData.light().copyWith(  
                textTheme: const TextTheme().apply(  
                    fontFamily:  
                    locale.languageCode == 'ar' ? 'Cairo' : 'Poppins')),
            cupertinoTheme:(locale) => const CupertinoThemeData(
              brightness: Brightness.light,
            ),
            colorScheme: LightColorScheme()),  
        XTheme(  
            id: 'dark',  
            nameBuilder: () => 'Dark',  
            theme: (locale) => ThemeData.dark().copyWith(  
                textTheme: const TextTheme().apply(  
                    fontFamily:  
                    locale.languageCode == 'ar' ? 'Cairo' : 'Poppins')),
            cupertinoTheme:(locale) => const CupertinoThemeData(
              brightness: Brightness.dark,
            ),
            colorScheme: DarkColorScheme()),  
      ];  
}  

For each theme you need to pass an id , name and theme data and you can also provide colors for each theme.
You can customize theme data based on each theme and your preferences.

Customize theme's colors

We can create custom colors for each theme.

Each theme can have its own colors that is configured in XThemeConfig as each XTheme have it's own colors.

To create custom colors , We can create for each theme a class that extends XColors
and define it's color values like primary and secondary.
For example :

class LightColors extends XColors{  
  @override  
  Color get background => XColors.white;  
  
  @override  
  Color get error => XColors.red;  
  
  @override  
  Color get onBackground => XColors.black;  
  }  

If you want to extend the colors that are defined in XColors
You can define another base class that extends XColors and adds more colors to it.
For example:

abstract class AppColors extends XColors{  
  ///Colors that needs to implemented for each theme.  
  Color get containerBackgroundColor;  
  
  ///Colors that needs to is used for each theme.  
  static const Color blue = Colors.blue;  
}  

Then, We can make each theme color scheme class to extend AppColors .
For example:

class LightColorScheme extends AppColors {  
  @override  
  Color get containerBackgroundColor => XColors.white;  
  
  @override  
  Color get background => XColors.white;  
  
  @override  
  Color get error => XColors.red;  
  
  @override  
  Color get onBackground => XColors.black;  
}  

Now we can have access to colors that defined in both XColors and AppColors in each theme color scheme.

Then, We can access each theme color scheme like this:

 final colorScheme = PlayxTheme.colorScheme as AppColors ;    
 final primary = colorScheme.primary;    

and use it in widget like this :

 @override  
 Widget build(BuildContext context) {  
   return ColoredBox(color: colorScheme.primary);  
 }  

Material 3:

You can use the package wheteher you are using Material 2 or Material 3 as you can configure theme data for each theme to whether use Material 3 or not.

The package contatins multiple utilites and widgets that can help you with using Material 3 in your app.

As you can use ImageTheme widget that is themed by image content by providing image provider as it generates color scheme from image content.

Also you can blend two color schemes together and returns a new color scheme using getBlendedColorScheme method. Also we have included flex_seed_scheme package which is more flexible and powerful version of Flutter's ColorScheme.fromSeed. Use multiple seed colors, custom chroma and tone mapping to enahce creating a color scheme for Material3.
