}

class _MyAppState extends State<MyApp> {
  bool isDarkMode = false;

  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      debugShowCheckedModeBanner: false,
      theme: isDarkMode ? ThemeData.dark() : ThemeData.light(),
      home: Scaffold(
        appBar: AppBar(
          title: const Text('Light/Dark Theme Toggle Example'),
          actions: [
            Padding(
              padding: const EdgeInsets.only(right: 16.0),
              child: LightDarkThemeToggle(
                value: isDarkMode,
                onChanged: (value) {

                    isDarkMode = value;
                  });

            },

// ... inside the MyApp widget's build method ...

body: Center(
  child: Wrap(
    spacing: 10,
    runSpacing: 10,
    runAlignment: WrapAlignment.center,
    alignment: WrapAlignment.center,
    children: [
      ...ThemeIconType.values.map(
        (themeIconType) {
          return Card(
            child: LightDarkThemeToggle(
              size: 128.0,
              themeIconType: themeIconType,
              value: isDarkMode,
              onChanged: (value) {
                setState(() {
                  isDarkMode = value;
                });
              },
            ),
          );
        },
      )
    ],
  ),
),
// ... rest of the widget ...

```
