class Event {

  DateTime date;

  Event(this.name, this.date);

class MyApp extends StatelessWidget {
  List<Event> events = [
    Event("Event 1", DateTime.now()),
    Event("Event 2", DateTime.now().add(Duration(days: 1))),
    Event("Event 3", DateTime.now().add(Duration(days: 2))),
  ];

  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      home: Scaffold(
        appBar: AppBar(
          title: Text('Event List'),
        ),
        body: ListView.builder(
          itemCount: events.length,
          itemBuilder: (context, index) {
            return ListTile(
              title: Text(events[index].name),
