util.dart(기존 코드)

final _kEventSource = {
   for (var item in List.generate(50, (index) => index))
     DateTime.utc(kToday.year, kToday.month, item * 5): List.generate(
         item % 4 + 1, (index) => Event('Event $item | ${index + 1}'))
 }..addAll({
     kToday: [
       Event('Today\'s Event 1'),
       Event('Today\'s Event 2'),
     ],
});
