+# 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
