## 代码规范要求
|
||||
|
||||
### 注释规范（强制要求）
|
||||
**所有代码文件必须包含中文注释**，具体要求：
|
||||
- **实体类**：每个字段必须有中文注释，说明字段用途和业务含义
|
||||
- **方法**：每个公共方法必须有中文注释，说明方法功能、参数含义、返回值
|
||||
- **类**：每个类必须有中文注释，说明类的职责和设计目的
|
||||
- **复杂逻辑**：算法或业务逻辑复杂的地方必须有详细中文注释
|
||||
- **常量**：所有常量必须有中文注释，说明常量用途
|
||||
- **数据库相关**：所有数据库模型、DAO、Repository必须有详细中文注释
|
||||
|
||||
**注释模板示例**：
|
||||
```dart
|
||||
/// 用户服务类 - 负责用户相关的业务逻辑处理
|
||||
/// 提供用户注册、登录、信息修改等功能
|
||||
class UserService {
|
||||
/// 用户唯一标识符 - UUID格式，全局唯一
|
||||
final String id;
|
||||
|
||||
/// 用户昵称 - 显示名称，支持2-20个字符
|
||||
final String nickname;
|
||||
|
||||
/// 构造函数 - 创建用户实例
|
||||
/// [id] 用户唯一标识符，不能为空
|
||||
/// [nickname] 用户昵称，不能为空
|
||||
UserService({required this.id, required this.nickname});
|
||||
|
||||
/// 更新用户昵称 - 修改用户显示名称
|
||||
/// 返回更新后的用户实例，保持不可变性
