+# ChatFloatingIcon 和 ChatPopup 组件说明
+
+这两个组件用于替代原来的 `FloatingIcon`，解决了在 Stack 中会被上层遮挡的问题。
+
+## 组件结构
+
+### ChatFloatingIcon
+可拖拽的悬浮图标组件，支持：
+- 自定义图标和大小
+- 拖拽功能（自动吸附屏幕边缘）
+- 长按开始语音输入
+- 点击进入全屏聊天
+- 多种动画效果
+
+### ChatPopup  
+基于 Overlay 的弹窗容器，负责：
+- 管理 PartScreen 的显示/隐藏
+- 根据图标位置自动计算弹窗位置
+- 处理背景点击关闭
+- 动画效果管理
+
+## 使用方法
+
+### 基本使用（默认AI图标）
+```dart
+ChatPopup(
+  child: ChatFloatingIcon(
+    iconSize: 80, // 可选，默认80
+  ),
+),
+```
+
+### 自定义图标
+```dart
+ChatPopup(
+  child: ChatFloatingIcon(
+    iconSize: 60,
+    icon: Container(
+      width: 60,
+      height: 60,
+      decoration: const BoxDecoration(
+        color: Colors.blue,
+        shape: BoxShape.circle,
+      ),
+      child: const Icon(Icons.chat, color: Colors.white),
+    ),
+  ),
+),
+```
+
+### 添加自定义回调
+```dart
+ChatPopup(
+  child: ChatFloatingIcon(
+    iconSize: 70,
+    onTap: () {
+      // 自定义点击事件
+    },
+    onPositionChanged: (position) {
+      // 位置变化回调
+    },
+    onDragStart: () {
+      // 拖拽开始
+    },
+    onDragEnd: () {
+      // 拖拽结束  
+    },
+  ),
+),
+```
+
+## 参数说明
+
+### ChatFloatingIcon 参数
+- `iconSize`: 图标大小，默认80
+- `icon`: 自定义图标Widget，不传则使用默认AI图标
+- `onTap`: 点击回调，默认进入全屏聊天
+- `onLongPress`: 长按开始回调，默认开始语音输入
+- `onLongPressUp`: 长按结束回调，默认结束语音输入
+- `onLongPressEnd`: 长按结束详细回调
+- `onDragStart`: 拖拽开始回调
+- `onDragEnd`: 拖拽结束回调  
+- `onPositionChanged`: 位置变化回调
+
+### ChatPopup 参数
+- `child`: 子组件，通常是ChatFloatingIcon
+- `chatSize`: 聊天框大小，默认320x450
+
+## 功能特性
+
+1. **避免遮挡**: 使用 Overlay 显示弹窗，不会被 Stack 上层遮挡
+2. **位置自适应**: 根据图标位置自动计算弹窗显示位置
+3. **保持原有逻辑**: 与原 FloatingIcon 功能完全兼容
+4. **灵活自定义**: 支持自定义图标、回调等
+5. **动画丰富**: 保持原有的各种动画效果
+
+## 迁移指南
+
+### 从 FloatingIcon 迁移
+原来的代码：
+```dart
+Stack(
+  children: [
+    // 其他内容
+    FloatingIcon(),
+  ],
+)
+```
+
+新的代码：
+```dart
+Stack(
+  children: [
+    // 其他内容
+    ChatPopup(
+      child: ChatFloatingIcon(),
+    ),
+  ],
+)
+```
+
+## 注意事项
+
+1. ChatPopup 必须在有 Overlay 的 Widget 树中使用（通常是 MaterialApp 下）
+2. 如果要自定义图标，建议保持圆形设计以匹配拖拽动画
+3. 长按语音输入功能需要 MessageService 正确配置
+4. 位置计算基于屏幕坐标，确保在正确的上下文中使用

+## **1. 引言**
+
+### **1.1 文档目的**
+
+本文档旨在定义“AI Chat Assistant Flutter Plugin”项目的详细功能需求、非功能需求、技术架构及项目规划。它为设计、开发、测试及项目相关人员提供了统一的参考依据和验收标准。
+
+### **1.2 适用范围**
+
+本文档目标读者为：AI Chat Assistant Flutter Plugin 的系统设计人员、开发人员、测试人员、产品经理以及项目管理人员。
+
+### **1.3 名词解释**
+
+| **序号** | **名词术语** | **名词解释** |
+| --- | --- | --- |
+| 1 | Flutter Plugin | 一种可复用的代码包，用于为Flutter应用添加特定的原生平台功能。 |
+| 2 | ASR | Automatic Speech Recognition，自动语音识别，将语音转换为文本。 |
+| 3 | TTS | Text-To-Speech，语音合成，将文本转换为语音。 |
+| 4 | SSE | Server-Sent Events，一种服务器向客户端推送数据的技术。 |
+| 5 | 车控命令 | 通过语音或界面触发的，用于控制车辆功能（如门锁、空调）的指令。 |
+| 6 | 场景（Scenario）| 不同业务上下文（购车 / 用车） |
+
+### **1.4 统一异常处理**
+
+1. **网络异常**：语音识别或AI对话过程中出现网络错误，应有明确提示（如：“网络连接失败，请检查后重试”），并提供重试选项。
+2. **权限拒绝**：当未授予麦克风或音频录制权限时，应引导用户前往系统设置开启权限。
+3. **语音识别失败**：返回空文本或低置信度，提示“抱歉，我没有听清，请再说一遍”。（补充：不缓存失败结果。）
+4. **命令执行失败**：车控执行失败需双通道反馈（UI + TTS），并显示失败原因或错误类型标签。（补充：通用错误尽量转化为用户友好语义。）
+
+## 2. 产品概述
+
+### 2.1 产品简介
+
+AI Chat Assistant 是一个集成语音识别、智能对话、车控指令解析与执行、语音反馈渲染于一体的 Flutter 插件。支持“车控助手”与“用车助手”双场景：  
+- 车控助手：支持 20+ 车辆控制命令（如空调、车窗、车门、座椅加热等）。  
+- 用车助手：基于用户手册 / 知识库进行问答。（包含 保养咨询、能耗优化建议等）
+- 购车助手：基于厂家的经销政策以及车辆配置信息进行问答
+
+### 2.2 产品流程图
+
+
+现有核心流程：用户长按语音按钮 → 权限校验 → 录音 + 识别 → 文本分类 → 路由到问答/车控/错误反馈 → 结果播报与展示。

+
+### 3.3 聊天模块
+
+#### **3.3.1 聊天气泡类型**
+
+- **用户场景**
+
+用户与AI助手对话过程中，会展示不同类型的聊天气泡以适应各种交互需求。
+
+- **功能描述**
+
+系统支持多种聊天气泡类型，包括文本气泡、卡片气泡、按钮气泡、链接气泡和富媒体气泡等，以满足不同场景下的交互需求。
+
+- **需求说明**
+    - 文本气泡：展示普通文字对话内容，完整支持Markdown格式；
+        Markdown支持包括普通文本格式化、表格布局以及图片嵌入，提供更丰富的内容展示方式
+    - 卡片气泡：用于展示结构化信息，如车辆信息、维保记录等；
+    - 按钮气泡：包含可交互按钮，用于快速回复或执行操作；
+    - 富媒体气泡：支持图片、视频、语音等多媒体内容展示；
+        富媒体气泡可能适用于显示特定的信息，或者是视频的教程，轮播的图片
+    - 链接气泡：用于显示一个链接，包含Icon，Title，Description，以及一个可以点击的链接；
+        点击链接可以进入webview，链接气泡主要是用于详细介绍某些活动或者查看详情
+    - 业务气泡：用于特定业务的定制化气泡，会根据对话的业务场景，显示不同的气泡。
+        业务气泡不同于其他的气泡，可以在用户询问金融方案后显示返回的计算结果，在结果后面还有一个按钮，可以进入金融计算器的页面；同时在用户说出我希望订购某款车型时，会出现车型的信息，并且有一个立即订购的按钮。业务气泡是根据返回的数据来判断具体的业务场景，混合显示的气泡类型。
+

+
+![业务气泡2](images/bussine_image.png)
+
+![聊天气泡](images/bubble_image_list.png)
+
+#### **3.3.2 普通问答流程**
+
+- **用户场景**
+
+用户与AI助手对话过程中，AI助手会把语音转换为文本，通过文本的语义来判断场景，是普通问答或者是车控指令
+
+- **功能描述**
+
+普通问答现在只有用车助手这个场景，后续增加新的场景：购车助手；需要先通过文本语义判断是哪个场景，然后根据相应场景来回复问题。
+
+- **需求说明**
+    - 场景识别由后端完成，前端仅消费分类结果
+    - SSE：按流片段累积，合并为 Markdown
+  
+不管是购车场景还是用车场景，或者是开放式对话，都有一个问答的流程，场景的区分不是前端来判断。现在流程是将语音转化的文本通过接口发给后台服务，然后后台会根据body里面的text和conversation_id 来返回一个文件流，客户端这边会把文件流的全部数据接受完成后合并为一个markdown语法的文本。
+
+```mermaid
+graph TD
+
+	A[文本数据] --> B{Chat api}
+	B --> C[文件流] --> D{SSE Service} --> E[Markdown文本]
+	E --> F{TTS} --> G[播放语音]
+	E --> H{Message} --> I[显示]
+
+```
+
+现在有两个新的调整方案，一个是Socket连接，另外一个方案是在现有的流程基础上新增消息类型。
+
+  1. Socket方案
+
+每次进入AI助手会话会创建一个随机的taskId，然后每次对话都会有一个conversationId，使用taskId 连接Socket成功后，就可以通过Socket发送语音或者文本消息。然后Socket 会返回三种不同的消息类型，`it消息 (识别文本)`，`gb消息 (回复文本)`，`tts消息 (语音数据)`。
+
+流程图如下：
+
+```mermaid
+sequenceDiagram
+    participant C as 客户端
+    participant S as 服务器
+
+    Note over C, S: 第一步：建立WebSocket连接
+    C->>S: WebSocket Handshake (携带认证信息)
+
+    Note over C, S: 第二步：客户端发送语音数据
+    C->>S: 发送消息: {taskId, conversationId, audioData}
+
+    Note over C, S: 第三步：服务器异步返回多条消息
+    par 并行处理与推送
+        S-->>C: it消息 (识别文本)
+        and
+        S-->>C: gb消息 (回复文本)
+        and
+        S-->>C: tts消息 (语音数据)
+    end
+
+    Note over C, S: 连接保持，可继续发送新语音或关闭
+```
+
+   2. HTTP方案
+
+HTTP方案是保持原有流程的情况下进行扩展，chat API 不再是返回一个数据流，而是返回一个json数据，json数据里面会有不同的消息返回，对应上面不同的气泡类型，消息类似分为`stream`，`text`，`media`，`bussines`，`stream`消息就是之前的数据流的消息，通过`messageId`就可以获取到数据；`text`消息是普通的文本消息，可以实现上面的链接气泡，按钮气泡；`media`消息则可以实现负责的图文混排，或者是一个单纯的视频教程；`bussines`消息主要以业务相关的，会根据业务类型显示不一样的样式，内容和按钮也会有变化。
+
+```json
+{
+	"conversationId": 1,
+	"taskId": "task_123",
+	"code": 200,
+	"scenario": "buying_assistant",
+	"messageList": [
+		{
+			"messageId": "messageId_xxxxx",
+			"type": "stream"
+		},
+		{
+			"messageId": "messageId_xxxxx",
+			"type": "text",
+			"content": "xxxxx"
+		},
+		{
+			"messageId": "messageId_xxxxx",
+			"type": "media"
+		},
+		{
+			"messageId": "messageId_xxxxx",
+			"type": "bussines",
+			"bussineType": "vehicle_commendation"
+		},
+	]
+}
+```
+
+#### **3.3.3 车控指令流程**
+
+- **用户场景**
+
+用户与AI助手对话过程中，AI助手会把语音转换为文本，通过文本的语义来判断场景，是普通问答或者是车控指令
+
+- **功能描述**
+
+如果根据分类结果，将语音或者文本信息归类为车控指令，则会进入车控指令的流程。识别语音指令中的车控意图，解析参数，并调用相应的车辆控制接口。
+
+- **需求说明**
+    - **命令识别**：支持识别20+种车控命令类型。
+    - **参数解析**：能从指令中解析出关键参数（如温度值、座椅位置）。
+    - **执行反馈**：命令执行成功或失败，都必须有明确的TTS和UI反馈。
+    - **可扩展性**：提供抽象类`VehicleCommandHandler`，允许开发者根据具体车型实现自定义控制逻辑。
+    - **支持命令示例**：
+        - **车门控制**：上锁、解锁
+        - **车窗控制**：开启、关闭
+        - **空调控制**：开启、关闭、温度调节、极速降温
+        - **座椅控制**：主/副驾驶座椅加热、通风
+        - **后备箱控制**：开启、关闭
+        - **特殊功能**：鸣笛、车辆定位、一键备车、一键融雪
+
+
+#### **3.3.4 聊天信息持久化**
+
+- **用户场景**
+
+用户在与AI助手进行对话时，会产生多条聊天记录。为保护用户隐私和提升体验，这些聊天记录默认仅保存在本地设备，不会上传至云端。
+
+- **功能描述**
+
+系统支持本地化持久化存储普通问答类型的聊天记录。所有文本类消息将以结构化数据形式保存至本地数据库（推荐使用SQLite或Hive等Flutter主流轻量级数据库），便于后续检索和管理。
+
+- **需求说明**
+    - **本地存储**：所有与AI助手的聊天记录（包括文本、语音、气泡类型、时间戳等）需保存在本地设备，支持持久化；
+    - **存储方式**：采用本地数据库（如SQLite、Hive等Flutter常用方案），或文件存储，保证数据安全和高效读写；
+    - **读取与展示**：用户重新进入聊天界面时，不会自动加载历史聊天记录，点击显示历史记录之后才会加载聊天记录，按时间顺序展示；
+    - **数据结构**：每条聊天记录需包含：消息ID、会话ID、消息类型（文本/语音/卡片/按钮/富媒体）、内容、时间戳、发送方（用户/AI）、气泡类型等；
+    - **删除与清理**：支持用户手动删除单条或全部聊天记录，支持定期自动清理（如超过30天自动删除）；
+    - **持久化逻辑**：在Socket和HTTP两种消息方案下，收到消息体后，系统会优先将stream和text类型消息持久化保存，其他类型消息仅用于即时展示，不做持久化处理。
+
+有了消息的持久化，AI助手聊天消息的显示逻辑也会跟着变化，按照上面的`Socket`方案和`HTTP`方案，收到消息体之后首先会保存到本地，特别是`HTTP`方案中会有多条消息返回，持久化只会保存stream和text消息，其他消息不会保存。
+
+```mermaid
+graph TD
+    A[收到AI助手消息] --> B[显示消息到聊天界面]
+    B --> C{消息类型判断}
+    C -->|stream/text| D[持久化保存到本地数据库]
+    C -->|其他类型| E[仅显示，不持久化]
+    D --> F[历史消息管理]
+    F --> G[用户点击显示历史记录]
+    G --> H[加载历史消息并展示]
+```
+
+## 4. 非功能需求
+
+### 4.1 服务模块
+
+#### **4.1.1 模块设计目标**
+
+服务模块负责“输入 → 解析 → 对话/车控 → 反馈 → 持久化”全链路的能力封装，向上提供简单一致的编程接口，向下屏蔽多种后端形态（HTTP / SSE）与原生能力（录音、TTS、权限、ASR）。  
+设计目标：

+- 初始化：
+```dart
+await AiChatCore.init(
+  config: CoreConfig(
+    endpoints: Endpoints(
+      classify: "...",
+      sse: "...",
+      ws: "...",
+      controlParse: "...",
+      controlExec: "...",
+      voice: "...",
+    ),
+    timeouts: Timeouts(connectMs: 8000, receiveMs: 20000),
+    enablePersistence: true,
+    persistenceMode: PersistenceMode.hive,
+    retryPolicy: RetryPolicy(maxAttempts: 2, backoffBaseMs: 400),
+  ),
+  commandHandler: MyVehicleCommandHandler(),
+  logger: CustomLogger(),
+);
+```
+
+- 统一公共接口：
+```dart
+abstract class AiChatCore {
+  static Future<void> init({required CoreConfig config, required VehicleCommandHandler commandHandler, Logger? logger});
+  static MessageService get messageService;
+  static PersistenceService? get persistence;
+}
+
+class MessageService {
+  Stream<List<Message>> get messageStream;
+  Future<void> startVoiceInput();
+  Future<void> stopAndProcessVoiceInput();
+  Future<void> sendText(String text);
+  Future<void> abortAnswer();
+  Future<void> loadHistory({required int page, required int pageSize});
+}
+```
+
+#### **4.1.6 编译与分发说明（path 子包 vs 单包）**
+- 当前结构：插件（ai_chat_assistant）+ 仓库内 path 依赖（packages/ai_chat_core、packages/basic_intl）。
+
+- 下游集成（pubspec）仅需：
+  ```yaml
+  ai_chat_assistant:
+    git:
+      url: <repo_url>
+      ref: <branch_or_tag>
+  ```
+- Flutter 构建行为：
+  1. 克隆仓库 → 解析主插件 pubspec → 解析 path 子包 → 汇总全部 Dart 源码。
+  2. Debug：JIT，Release：统一 AOT 编译为一个 snapshot（无包边界差异）。
+- 性能与产物差异：将子包“内联”进 lib/ 与保持 path 组织，在编译后无本质差异（tree shaking 后输出等价）。
+- 适用场景对比：
+  | 目标 | 保持多包 | 合并单包 |
+  | ---- | -------- | -------- |
+  | 代码隔离 / 复用 | 优 | 弱 |
+  | 发布到 pub.dev | 需逐包发布 | 更简单 |
+  | 测试隔离性 | 优 | 一般 |
+  | 用户认知成本 | 稍高 | 低 |
+- 暂不需发布：保持 path 结构即可；若未来开放生态 → 发布次序：ai_chat_core → basic_intl → ai_chat_assistant。
+
+#### **4.1.7 AAR 与闭源分发说明**
+| 诉求 | 可行性 | 说明 |
+| ---- | ------ | ---- |
+| 给“另一个 Flutter App”仅提供预编译 AAR 使用 | 不推荐/不可行 | Flutter 仍需源文件参与整体编译流程 |
+| 给纯原生 Android App 内嵌使用 | 可用 `flutter build aar` | 适用于“原生 App 集成 Flutter 模块”，不是插件分发 |
+| Dart 逻辑闭源 | 官方未支持 | 只能转移核心到 native/FFI 或服务端 |
+
+结论：对 Flutter 使用方，直接 Git 依赖即可，无需 AAR。
+

+    print('执行车控命令: ${command.type}, 参数: ${command.params}');
+
+    // 更新命令状态为执行中
+    commandCubit?.emit(AIChatCommandState(
+      commandId: command.commandId,
+      commandType: command.type,
+      params: command.params,
+      status: AIChatCommandStatus.executing,
+      timestamp: DateTime.now(),
+    ));
+
+    // 模拟命令执行
+    await Future.delayed(const Duration(seconds: 2));
+
+    // 更新命令状态为成功
+    commandCubit?.emit(AIChatCommandState(
+      commandId: command.commandId,
+      commandType: command.type,
+      params: command.params,
+      status: AIChatCommandStatus.success,
+      timestamp: DateTime.now(),
+      result: {'message': '命令执行成功'},
+    ));
+
+    return (true, {'message': '命令已执行'});
+  }
+}
+```
+
+### 初始化示例
+
+```dart
+void main() async {
+  WidgetsFlutterBinding.ensureInitialized();
+
+  // 请求麦克风权限
+  if (!await Permission.microphone.isGranted) {
