当然，以下是一个关于如何在Flutter项目中使用table_calendar插件来展示日历的示例代码。这个示例将展示如何集成table_calendar插件，并处理日历的选择事件。

首先，你需要在pubspec.yaml文件中添加table_calendar依赖：

dependencies:
  flutter:
    sdk: flutter
  table_calendar: ^3.0.5  # 请检查最新版本号

然后，运行flutter pub get来安装依赖。

接下来，在你的Flutter项目中创建一个展示日历的页面。以下是一个完整的示例代码：

import 'package:flutter/material.dart';
import 'package:table_calendar/table_calendar.dart';

void main() {
  runApp(MyApp());
}

class MyApp extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      title: 'Flutter Calendar Demo',
      theme: ThemeData(
        primarySwatch: Colors.blue,
      ),
      home: CalendarPage(),
    );
  }
}

class CalendarPage extends StatefulWidget {
  @override
  _CalendarPageState createState() => _CalendarPageState();
}

class _CalendarPageState extends State<CalendarPage> with SingleTickerProviderStateMixin {
  CalendarController _controller;
  Map<DateTime, List<dynamic>> _events;

  @override
  void initState() {
    super.initState();

    _controller = CalendarController();

    // 初始化一些示例事件
    _events = {};

    // 添加一些示例事件到特定日期
    _addEvent(DateTime date, String title) {
      if (!_events.containsKey(date)) {
        _events[date] = [];
      }
      _events[date]!.add(title);
    }

    // 添加一些示例数据
    _addEvent(DateTime(2023, 10, 5), 'Event 1');
    _addEvent(DateTime(2023, 10, 15), 'Event 2');
    _addEvent(DateTime(2023, 10, 25), 'Event 3');
  }

  @override
  void dispose() {
    _controller.dispose();
    super.dispose();
  }

  @override
  Widget build(BuildContext context) {
    return Scaffold(
      appBar: AppBar(
        title: Text('Flutter Calendar Demo'),
      ),
      body: SingleChildScrollView(
        child: Column(
          crossAxisAlignment: CrossAxisAlignment.start,
          children: <Widget>[
            TableCalendar(
              _controller,
              events: _events,
              initialCalendarFormat: CalendarFormat.month,
              startingDayOfWeek: StartingDayOfWeek.monday,
              calendarStyle: CalendarStyle(
                todayColor: Colors.blue,
                selectedColor: Colors.deepOrange.withOpacity(0.3),
                todayStyle: TextStyle(fontWeight: FontWeight.bold),
                selectedTextStyle: TextStyle(color: Colors.white, fontWeight: FontWeight.bold),
                daysOfWeekStyle: TextStyle(color: Colors.grey[800]),
              ),
              headerStyle: HeaderStyle(
                centerHeaderTitle: true,
                formatButtonTextStyle: TextStyle(color: Colors.white, fontWeight: FontWeight.bold),
                decoration: BoxDecoration(
                  color: Colors.blue,
                ),
              ),
              builders: CalendarBuilders(
                selectedDayBuilder: (context, date, events) => Container(
                  margin: const EdgeInsets.all(4.0),
                  alignment: Alignment.center,
                  decoration: BoxDecoration(
                    color: Colors.deepOrange,
                    shape: BoxShape.circle,
                  ),
                  child: Text(
                    date.day.toString(),
                    style: TextStyle(color: Colors.white),
                  ),
                ),
                todayDayBuilder: (context, date, events) => Container(
                  margin: const EdgeInsets.all(4.0),
                  alignment: Alignment.center,
                  decoration: BoxDecoration(
                    color: Colors.blue.withOpacity(0.1),
                    shape: BoxShape.circle,
                  ),
                  child: Text(
                    date.day.toString(),
                    style: TextStyle(color: Colors.blue, fontWeight: FontWeight.bold),
                  ),
                ),
                markerBuilder: (context, date, events) => Badge(
                  badgeContent: Text(events.length.toString()),
                ),
              ),
              onDaySelected: (date, events) {
                setState(() {});
              },
              onVisibleDaysChanged: (days, month) {
                setState(() {});
              },
              onCalendarCreated: (CalendarController controller) {
                setState(() {});
              },
            ),
            // 显示选定日期的事件
            SizedBox(height: 10.0),
            Expanded(
              child: _buildEventList(),
            ),
          ],
        ),
      ),
    );
  }

  Widget _buildEventList() {
    return ListView.builder(
      shrinkWrap: true,
      itemCount: _controller.selectedEvents.length,
      itemBuilder: (context, index) {
        final event = _controller.selectedEvents[index];
        return Container(
          decoration: BoxDecoration(
            border: Border.all(color: Colors.grey),
            borderRadius: BorderRadius.circular(10),
          ),
          margin: EdgeInsets.symmetric(horizontal: 8.0, vertical: 4.0),
          child: ListTile(
            leading: Icon(Icons.event),
            title: Text(event.toString()),
          ),
        );
      },
    );
  }
}

class Badge extends StatelessWidget {
  final Widget badgeContent;

  const Badge({Key? key, required this.badgeContent}) : super(key: key);

  @override
  Widget build(BuildContext context) {
    return Stack(
      alignment: Alignment.topRight,
      children: <Widget>[
        Positioned(
          right: -4,
          top: -4,
          child: Container(
            padding: EdgeInsets.all(2),
            decoration: BoxDecoration(
              color: Colors.redAccent,
              borderRadius: BorderRadius.circular(6),
            ),
            constraints: BoxConstraints(minWidth: 18, minHeight: 18),
            child: badgeContent,
          ),
        ),
      ],
    );
  }
}

在这个示例中，我们做了以下几件事：

1. 初始化CalendarController：用于控制日历的显示和行为。
2. 初始化事件数据：_events是一个映射，将日期映射到事件列表。
3. 构建日历：使用TableCalendar小部件，并配置样式和事件构建器。
4. 处理选择事件：通过onDaySelected回调处理日期选择事件。
5. 显示选定日期的事件：在日历下方显示选定日期的事件列表。

这个示例代码提供了一个基础的日历展示和处理事件的框架，你可以根据需要进一步自定义和扩展。
