삭제 기능

void _confirmDelete(String id) async {
  final confirmed = await showDialog<bool>(
    context: context,
    builder: (context) => AlertDialog(
      title: const Text('삭제 확인'),
      content: const Text('이 일기를 삭제하시겠습니까?'),
      actions: [
        TextButton(
          onPressed: () => Navigator.pop(context, false),
          child: const Text('취소'),
        ),
        TextButton(
          onPressed: () => Navigator.pop(context, true),
          child: const Text('삭제'),
        ),
      ],
    ),
  );

  if (confirmed == true) {
    await diaryBox.delete(id);
    setState(() {}); // 리스트 갱신
  }
}

감정 차트 시각화 기능

import 'package:flutter/material.dart';
import 'package:hive/hive.dart';
import '../models/diary_entry.dart';
import 'package:fl_chart/fl_chart.dart';

class EmotionChart extends StatelessWidget {
  const EmotionChart({super.key});

  @override
  Widget build(BuildContext context) {
    final box = Hive.box<DiaryEntry>('diaryBox');
    final entries = box.values.toList();

    final emotionCount = <String, int>{};

    for (var entry in entries) {
      emotionCount[entry.emotion] = (emotionCount[entry.emotion] ?? 0) + 1;
    }

    final sections = emotionCount.entries.map((e) {
      final emotion = e.key;
      final count = e.value;
      return PieChartSectionData(
        value: count.toDouble(),
        title: '$emotion\\n$count',
        radius: 60,
        color: _colorForEmotion(emotion),
        titleStyle: const TextStyle(fontSize: 14, color: Colors.white),
      );
    }).toList();

    return PieChart(
      PieChartData(
        sections: sections,
        sectionsSpace: 2,
        centerSpaceRadius: 32,
      ),
    );
  }

  Color _colorForEmotion(String emotion) {
    switch (emotion.toLowerCase()) {
      case 'happy':
        return Colors.yellow;
      case 'sad':
        return Colors.blue;
      case 'angry':
        return Colors.red;
      case 'neutral':
        return Colors.grey;
      default:
        return Colors.green;
    }
  }
}

일기 요약 수정

class DiaryDetailScreen extends StatefulWidget {
  final DiaryEntry entry;

  const DiaryDetailScreen({super.key, required this.entry});

  @override
  State<DiaryDetailScreen> createState() => _DiaryDetailScreenState();
}

class _DiaryDetailScreenState extends State<DiaryDetailScreen> {
  late TextEditingController _summaryController;

  @override
  void initState() {
    super.initState();
    _summaryController = TextEditingController(text: widget.entry.summary);
  }

  void _saveSummary() async {
    final box = Hive.box<DiaryEntry>('diaryBox');
    final updated = widget.entry.copyWith(summary: _summaryController.text);
    await box.put(widget.entry.id, updated);
    Navigator.pop(context);
  }

  @override
  Widget build(BuildContext context) {
    return Scaffold(
      appBar: AppBar(title: const Text('일기 상세')),
      body: Padding(
        padding: const EdgeInsets.all(16.0),
        child: Column(
          crossAxisAlignment: CrossAxisAlignment.start,
          children: [
            Text('날짜: ${widget.entry.createdAt.toLocal().toString().split(' ')[0]}',
                style: const TextStyle(fontSize: 16)),
            const SizedBox(height: 16),
            const Text('요약 수정:', style: TextStyle(fontSize: 16)),
            const SizedBox(height: 8),
            TextField(
              controller: _summaryController,
              maxLines: 3,
              decoration: const InputDecoration(
                border: OutlineInputBorder(),
              ),
            ),
            const SizedBox(height: 16),
            ElevatedButton(
              onPressed: _saveSummary,
              child: const Text('저장'),
            ),
          ],
        ),
      ),
    );
  }
