# 日历事件创建功能实现计划

> **For Claude:** REQUIRED SUB-SKILL: Use superpowers:executing-plans to implement this plan task-by-task.

**Goal:** 在日历月视图和日视图右上角添加 + 号图标，点击后弹出底部表单创建日历事件，创建完成后在视图中正确显示，并可点击进入详情页查看和编辑。

**Architecture:** 
- 使用 Mock Service 模式存储日历事件（参考 mock_history_service.dart）
- 底部弹窗表单使用 showModalBottomSheet
- 日视图使用时间线布局显示事件

**Tech Stack:** Flutter, BLoC, go_router, lucide_icons

## Task 1: 创建日历事件数据模型

**Files:**
- Create: `apps/lib/features/calendar/data/models/schedule_item_model.dart`

**Step 1: 创建数据模型文件**

}

const defaultColors = [

  Color(0xFF10B981), // 绿色
  Color(0xFFF59E0B), // 黄色
  Color(0xFFEF4444), // 红色
];
```

**Step 2: 提交**

```bash
git add apps/lib/features/calendar/data/models/schedule_item_model.dart
git commit -m "feat(calendar): 添加日历事件数据模型"

## Task 8: 更新事件详情页支持编辑和删除

**Files:**
- Modify: `apps/lib/features/calendar/ui/screens/calendar_event_detail_screen.dart`

**Step 1: 修改详情页接收事件 ID 并加载数据**

```dart
import 'package:flutter/material.dart';
import 'package:lucide_icons/lucide_icons.dart';
import 'package:go_router/go_router.dart';
import '../../../../core/theme/design_tokens.dart';
import '../../data/services/mock_calendar_service.dart';
import '../../data/models/schedule_item_model.dart';
import '../widgets/create_event_sheet.dart';

class CalendarEventDetailScreen extends StatefulWidget {
  final String eventId;

  const CalendarEventDetailScreen({super.key, required this.eventId});

  @override
  State<CalendarEventDetailScreen> createState() => _CalendarEventDetailScreenState();
}

class _CalendarEventDetailScreenState extends State<CalendarEventDetailScreen> {
  ScheduleItemModel? _event;

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

  void _loadEvent() {
    _event = CalendarService().getEventById(widget.eventId);
  }

  @override
  Widget build(BuildContext context) {
    if (_event == null) {
      return Scaffold(
        body: Center(child: Text('Event not found', style: TextStyle(color: AppColors.slate600))),
      );
    }
    // ... 其余代码使用 _event 而不是硬编码数据
  }
}
```

**Step 2: 修改 router 传递 eventId**

```dart
// in app_router.dart
GoRoute(
  path: '/calendar/events/:id',
  builder: (context, state) => CalendarEventDetailScreen(
    eventId: state.pathParameters['id']!,
  ),
),
```

**Step 3: 添加编辑和删除功能**

在详情页的编辑和删除按钮上添加：

```dart
// 编辑按钮
GestureDetector(
  onTap: () => CreateEventSheet.edit(context, _event!),
  child: Container(...),
),

// 删除按钮
GestureDetector(
  onTap: () => _showDeleteConfirmation(),
  child: Container(...),
),

void _showDeleteConfirmation() {
  showDialog(
    context: context,
    builder: (context) => AlertDialog(
      title: const Text('删除日程'),
      content: const Text('确定要删除这个日程吗？'),
      actions: [
        TextButton(onPressed: () => Navigator.pop(context), child: const Text('取消')),
        TextButton(
          onPressed: () {
            CalendarService().deleteEvent(widget.eventId);
            Navigator.pop(context);
            context.pop();
          },
          child: Text('删除', style: TextStyle(color: AppColors.red500)),
        ),
      ],
    ),
  );
}
```

**Step 4: 提交**

```bash
git add apps/lib/features/calendar/ui/screens/calendar_event_detail_screen.dart
git add apps/lib/core/router/app_router.dart
git commit -m "feat(calendar): 详情页支持编辑和删除事件"
```

## Task 9: 运行测试并验证

**Step 1: 运行 Flutter 测试**

```bash
cd apps
flutter test
```

**Step 2: 验证构建**

```bash
flutter build apk --debug
```

**Step 3: 提交**

```bash
git commit -m "chore(calendar): 测试通过并验证构建"
```

## 执行选项

**Plan complete and saved to `docs/plans/2026-03-02-calendar-create-event-design.md`. Two execution options:**

**1. Subagent-Driven (this session)** - I dispatch fresh subagent per task, review between tasks, fast iteration

**2. Parallel Session (separate)** - Open new session with executing-plans, batch execution with checkpoints

**Which approach?**
