     storybook,
     devices: { Devices.ios.iPhoneSE, Devices.android.pixel4, Devices.ios.iPadAir4 },
     filterStories: (Story story) {
       final skipStories = [];
       return !skipStories.contains(story.name);
     },
   );
   
   final storybook = Storybook(
     stories: [
       Story(
         name: 'Button',
         builder: (context) => ElevatedButton(
           onPressed: () {},
           child: const Text('Button'),
         ),
       ),
       Story(
         name: 'CounterPage',
         builder: (context) => const CounterPage(),
       ),
     ],
   );
