  return AnimatedNightReader(
    value: 1,
    duration: const Duration(seconds: 2),
    child: MaterialApp(
      title: 'Flutter Demo',
      theme: ThemeData(primarySwatch: Colors.blue),
      home: const MyHomePage(title: 'Flutter Demo Home Page'),

      child: Column(
        crossAxisAlignment: CrossAxisAlignment.center,
        children: [

            tint: Colors.blue,
            value: value1,
            duration: const Duration(seconds: 2),
