I watched a video about Syncfusion Calendar, and while it worked as an independent widget, it kind of never works when we tried implementing it for our application. It yields us with either a blank screen or the Appbar and the FloatingActionButton appearing only. How can I make it visible?

Mind the fact that we are not making this widget the main page and has to be accessible from the dashboard itself.

```
class CalendarTeacherPage extends StatefulWidget {
  const CalendarTeacherPage({Key? key}) : super(key: key);

  @override
  _CalendarTeacherPageState createState() => _CalendarTeacherPageState();
}

class _CalendarTeacherPageState extends State<CalendarTeacherPage> {
  @override
  Widget build(BuildContext context) {
    return Scaffold(
      body: Container(child: const CalendarWidget()),
      appBar: AppBar(
        title: const Text('Calendar'),
        centerTitle: true,
      ),
      floatingActionButton: FloatingActionButton(
        child: const Icon(Icons.add, color: Colors.white),
        backgroundColor: Colors.red,
        onPressed: () => Navigator.of(context).push(
          MaterialPageRoute(builder: (context) => const EventEditingPage()),
        ),
      ),
    );
  }
}

```

This one is for our CalendarWidget, which we believe to be holding the errors.

```
class CalendarWidget extends StatelessWidget {
  const CalendarWidget({Key? key}) : super(key: key);

  @override
  Widget build(BuildContext context) {
    final events = Provider.of<EventProvider>(context).events;

    return SfCalendar(
      view: CalendarView.schedule,
      dataSource: EventDataSource(events),
      initialSelectedDate: DateTime.now(),
      cellBorderColor: Colors.transparent,
      onLongPress: (details) {
        final provider = Provider.of<EventProvider>(context, listen: true);

        provider.setDate(details.date!);
        showModalBottomSheet(
          context: context,
          builder: (context) => const TasksWidget(),
        );
      },
    );
  }
}

```

Migrating this code from the SfCalendar acting as the main widget to it being part of our dashboard has proven difficult, and I just know that the issue is in the SfCalendar and where I am placing it. How do I fix this?
