+# ImageFind Mobile
+
+ImageFind 的 Flutter Android / iOS 客户端。客户端只连接后端 `/api/v1`，不依赖或复用 Web 前端代码。
+
+## 本地运行
+
+```powershell
+C:\Users\nanxun\Documents\flutter\bin\flutter.bat --no-version-check pub get
+C:\Users\nanxun\Documents\flutter\bin\flutter.bat --no-version-check run
+```
+
+首次启动后填写已开启“直接 Web/API 访问”的 ImageFind 地址。局域网地址可以使用 HTTP，公网地址必须使用 HTTPS。
+
+## 已实现
+
+- 安全会话：服务发现、首次设置、登录、CSRF、加密凭据存储
+- 自适应界面：手机底栏、平板导航 Rail、宽屏双栏
+- 首页、搜索、资料库、人物、合集、个人与服务工作台
+- 文字搜索和图片 multipart 搜索
+- 原始 Range 播放、HLS 回退、进度同步、逐字稿和收藏时刻
+- 设备视频分块上传及已接收分块续传
+- 本机 `.part` Range 续传下载、Drift 状态持久化和离线播放
+- SSE 断线重连及核心 Riverpod 数据刷新
+
+## 验证
+
+```powershell
+C:\Users\nanxun\Documents\flutter\bin\flutter.bat --no-version-check analyze
