  final AsyncValue<String, Exception> value;

  const MyWidget({super.key, required this.value});

      value: value,
      initial: (_) => ElevatedButton(
        onPressed: () => print('Fetch data'),
        child: const Text('Start'),
      ),
      loading: (_) => const CircularProgressIndicator(),
      data: (_, data) => Text('Fetched: $data'),
