问题：注册按钮只更新了显示列表，没有将特征标识和ID存入映射表
修复：
- 添加 _currentFaceKeys 保存当前帧的人脸特征标识
- 注册时将特征标识和生成的ID存入 _faceIdMap
- 下次检测时可以从映射表中找到已注册的ID

+# Quick Task 260330-ll6: Summary
+
+## Task
+注册完成后并不会显示用户已注册，检查一下注册流程和检测流程。
+
+## Problem Analysis
+**问题根源**：
+1. 检测时，`_getFaceKey()` 生成人脸特征标识
+2. 注册按钮只更新了 `_currentFaceIds` 列表，但**没有将特征标识和ID存入 `_faceIdMap`**
+3. 下次检测时，`_faceIdMap` 为空，所有人脸都显示"未注册"
+
+## Fix
+### `example/lib/main.dart`
+1. **添加状态变量**: `_currentFaceKeys` - 保存当前帧的人脸特征标识列表
+2. **修改检测流程**: 同时保存特征标识和ID
+3. **修改注册流程**: 注册时将特征标识和生成的ID存入 `_faceIdMap`
+
+## Code Changes
+
+```dart
+// 新增: 保存当前帧的人脸特征标识
+List<String> _currentFaceKeys = [];
+
+// 检测时: 同时保存特征标识
+_currentFaceKeys = faceList.map((face) => _getFaceKey(face)).toList();
+_currentFaceIds = _currentFaceKeys.map((key) => _faceIdMap[key] ?? '未注册').toList();
+
+// 注册时: 将特征标识和ID存入映射表
+_faceIdMap[faceKey] = newId;
+```
+
+## Verification
+- `flutter analyze lib/main.dart` - No issues found
