  State<MyHomePage> createState() => _MyHomePageState();
}

class _MyHomePageState extends State<MyHomePage> {
  @override
  Widget build(BuildContext context) {
    return Scaffold(
      appBar: AppBar(
        backgroundColor: Theme.of(context).colorScheme.inversePrimary,
        title: Text(widget.title),
      ),
      body: ScrollToAnimateTab(
        activeTabDecoration: TabDecoration(
          textStyle: const TextStyle(

            body: ListView.builder(
              shrinkWrap: true,
              physics: const NeverScrollableScrollPhysics(),
              itemCount: 10,
              itemBuilder: (_, index) => ListTile(
                title: Text('List element ${index + 1}'),
              ),
            )
          ),
          ScrollableList(
            label: "hello 2",
            body: Column(
              children: List.generate(
                10,
                (index) => ListTile(
                  title: Text('List element ${index + 1}')
                )

            body: ListView.builder(
              shrinkWrap: true,
              physics: const NeverScrollableScrollPhysics(),
              itemCount: 10,
              itemBuilder: (_, index) => ListTile(
                title: Text('List element ${index + 1}')
              )
            )
          ),
          ScrollableList(
            label: "hello",
            body: ListView.builder(
              shrinkWrap: true,
              physics: const NeverScrollableScrollPhysics(),
              itemCount: 10,
              itemBuilder: (_, index) => ListTile(
                title: Text('List element ${index + 1}')
              )
            )
          ),
          ScrollableList(
            label: "hola",
            body: ListView.builder(
              shrinkWrap: true,
              physics: const NeverScrollableScrollPhysics(),
              itemCount: 10,
              itemBuilder: (_, index) => ListTile(
                title: Text('List element ${index + 1}')
              )
