## 核心功能模块

### 1. 用户偏好设置

#### 个人信息设置
```dart
// 个人信息设置服务
class ProfileSettingsService {
  final SettingRepository _settingRepository;
  final StorageService _storageService;
  
  ProfileSettingsService(this._settingRepository, this._storageService);
  
  // 获取用户个人信息设置
  Future<Result<UserProfileSettings>> getUserProfileSettings() async {
    try {
      final settings = await _settingRepository.getUserProfileSettings();
      return Right(settings);
    } catch (e) {
      return Left(SettingFailure.loadFailed(e.toString()));
    }
  }
  
  // 更新用户头像
  Future<Result<void>> updateUserAvatar(String avatarUrl) async {
    try {
      await _settingRepository.updateUserAvatar(avatarUrl);
      await _storageService.setString('user_avatar', avatarUrl);
      return Right(unit);
    } catch (e) {
      return Left(SettingFailure.updateFailed(e.toString()));
    }
  }
  
  // 更新用户昵称
  Future<Result<void>> updateUserNickname(String nickname) async {
    try {

  AppPreferenceService(this._storageService);
  
  // 获取应用偏好设置
  Future<AppPreferenceSettings> getAppPreferences() async {
    final json = await _storageService.getObject('app_preferences') ?? {};
    return AppPreferenceSettings.fromJson(json);
  }
  
  // 保存应用偏好设置
  Future<void> saveAppPreferences(AppPreferenceSettings settings) async {
    await _storageService.setObject('app_preferences', settings.toJson());
    
    // 通知其他模块设置变更
    _notifySettingsChanged(settings);
  }
  
  // 更新语言设置
  Future<void> updateLanguage(String language) async {
    final settings = await getAppPreferences();
    final updatedSettings = settings.copyWith(language: language);
    await saveAppPreferences(updatedSettings);
  }
  
  // 更新主题设置
  Future<void> updateTheme(String theme, bool enableDarkMode) async {
    final settings = await getAppPreferences();
    final updatedSettings = settings.copyWith(
      theme: theme,

class SettingsStorageManager {
  final StorageService _storageService;
  
  SettingsStorageManager(this._storageService);
  
  // 保存设置到本地
  Future<void> saveSettings<T>(String key, T settings) async {
    await _storageService.setObject(key, settings.toJson());
  }
  
  // 从本地加载设置
  Future<T?> loadSettings<T>(
    String key,
    T Function(Map<String, dynamic>) fromJson,
  ) async {
    final json = await _storageService.getObject(key);
    if (json != null) {
      return fromJson(json);
    }
    return null;
  }
  
  // 同步设置到云端
  Future<void> syncSettingsToCloud() async {
    // 实现云端同步逻辑
  }
}
```

## 错误处理

### 设置特定异常
```dart
// 设置功能异常
abstract class SettingFailure {
  const SettingFailure();
  
  factory SettingFailure.loadFailed(String message) = LoadFailure;
  factory SettingFailure.updateFailed(String message) = UpdateFailure;
  factory SettingFailure.clearCacheFailed(String message) = ClearCacheFailure;
  factory SettingFailure.biometricNotAvailable() = BiometricNotAvailableFailure;
  factory SettingFailure.biometricAuthFailed() = BiometricAuthFailure;
}

class LoadFailure extends SettingFailure {
  final String message;
  const LoadFailure(this.message);
}
```
