+# 一、总体目标与边界
+
+## 1.1 目标
+
+基于现有后端接口，建设一套统一的埋点 SDK，覆盖：
+
+- 技术栈：
+  - Flutter：**独立纯 Dart SDK**
+  - Android：原生 Kotlin SDK
+  - iOS：原生 Swift SDK
+- 对齐后端接口：
+  - `GET /api/ExternalEventlogs/GetSystemAllDimInfo`
+  - `POST /api/ExternalEventlogs/AddEventListLog`
+  - `POST /api/ExternalEventlogs/AddEventLog`
+- 三阶段演进：
+  - Phase 1：可用性 + 安全稳定性
+  - Phase 2：可维护性 + 配置化 + 调试
+  - Phase 3：可观测性 + 动态策略 + 插件化
+
+不绑定具体业务逻辑，但要能支持 OA、教育等各类场景。
+
+## 1.2 统一事件数据模型
+
+### 请求结构（与后端对齐）
+
+jsonc
+
+```
+{
+  "system_code": "string",
+  "eventType": "string",
+  "userInfo": {
+    "userId": 0,
+    "userName": "string",
+    "account": "string"
+  },
+  "clientType": 1,
+  "clientTimestamp": 0,
+  "timestamp": "2026-01-26T08:29:44.734Z",
+  "deviceInfo": {
+    "os": "string",
+    "model": "string",
+    "screenResolution": "string"
+  },
+  "eventParams": {
+    // 事件上下文，例如 page、buttonId、url…
+  },
+  "customTags": {
+    // 扩展维度，业务可自定义
+  }
+}
+```
+
+### 统一对外 API 设计（跨三端）
+
+（伪接口，三端风格尽量保持一致）
+
+ts
+
+```
+class Analytics {
+  static init(config: SDKConfig): void | Future<void>
+
+  static track(
+    eventType: string,
+    options?: {
+      eventParams?: Map<string, any>
+      customTags?: Map<string, any>
+      timestamp?: number  // 毫秒级 client 时间，可不传
+    }
+  ): void | Future<void>
+
+  static setUser(userInfo: UserInfo | null): void | Future<void>
+
+  static setDeviceInfo(deviceInfo: DeviceInfo): void | Future<void>
+
+  static flush(): void | Future<void>
+
+  static setDebug(enabled: boolean): void
+}
+```
+
+`SDKConfig` 关键字段（统一）：
+
+- `systemCode: string`
+- `endpointBaseUrl: string`（如 `https://host/api/ExternalEventlogs`）
+- `clientType: int`（统一约定：1=Android，2=iOS，3=Flutter）
+- `enableDebug: boolean`
+- `batchSize: int`（默认 20）
+- `flushInterval: int`（秒，默认 15）
+- `maxCacheSize: int`（默认 5000）
+- `maxRetryCount: int`（默认 3）
+- `connectTimeout`, `readTimeout`
+
+------
+
+# 二、整体架构设计（通用视角）
+
+SDK 内部统一分层：
+
+1. **API 层（Facade）**  
+   - 暴露 `init / track / flush / setUser / setDebug`
+   - 做参数校验、线程切换（原生）。
+2. **EventManager（事件管理层）**  
+   - 构造标准事件对象（填充 system_code、userInfo、deviceInfo、时间）。
+   - 写入本地队列；触发上传调度。
+3. **Storage（存储层）**  
+   - 事件持久化（SQLite / 本地 KV）。
+   - 控制队列长度、过期清理。
+4. **NetworkClient（网络层）**  
+   - 封装调用：`AddEventListLog`（优先）、`AddEventLog`（可选降级）。
+   - 统一超时、重试、错误处理。
+5. **Config / DimensionManager（配置 & 维度）**  
+   - 管理 SDKConfig。
+   - Phase 2+：拉取 `GetSystemAllDimInfo`，存本地。
+6. **Validator / Debug（校验 & 调试）**  
+   - Phase 2+：基于配置做事件参数校验。
+   - 统一 debug 日志输出。
+7. **Interceptors / Plugins（插件层）**  
+   - Phase 3：对事件发送前后提供 Hook。
+
+------
+
+# 三、三端实现策略
+
+## 3.1 Flutter 独立 SDK（纯 Dart）
+
+- 语言：Dart
+- 存储：推荐 `sqflite`（SQLite）或 `hive`（KV）：
+  - `events(id, payload_json, retry_count, create_time)`
+- 网络：`dio` 或 `http` 包
+- 调度：
+  - `Timer.periodic` 实现定时 flush
+  - 控制并发：用一个「上传中」标志避免并发多次 flush
+- 生命周期：
+  - SDK 暴露 `flush()`；
+  - 应用可在自身生命周期（如 `WidgetsBindingObserver` 或 Router）中调用。
+
+## 3.2 Android SDK
+
+- 语言：Kotlin（对 Java 兼容）
+- 存储：Room 或 SQLite 封装
+- 网络：OkHttp + Retrofit
+- 线程：Kotlin Coroutines + 单一上传协程
+- 生命周期：`ProcessLifecycleOwner` 监听前后台 → 后台前触发 `flush`
+
+## 3.3 iOS SDK
+
+- 语言：Swift（暴露 ObjC 兼容 API）
+- 存储：SQLite 或 Core Data 轻量封装
+- 网络：URLSession
+- 生命周期：监听 `willResignActive` / `didEnterBackground` 调用 `flush`
+
+------
+
+# 四、三阶段规划（含架构与验收）
+
+------
+
+## Phase 1：可用性 + 安全稳定性
+
+### 4.1 目标
+
+- 提供稳定、可用的基础事件采集 & 批量上报能力。
+- 不影响业务性能和体验。
+- 基本安全（HTTPS，预留签名扩展）。
+
+### 4.2 能力范围
+
+1. 初始化
+   - 校验并保存 `SDKConfig`；
+   - 自动采集 `DeviceInfo`；
+   - 初始化本地存储；
+   - 启动定时 flush 调度（根据 flushInterval）。
+2. 事件写入（track）
+   - 检查 SDK 是否已 init；
+   - 构造 Event：
+     - `system_code` from config
+     - `eventType` from 调用
+     - `userInfo` from `setUser`
+     - `clientType` from config
+     - `clientTimestamp` = 当前毫秒时间戳
+     - `timestamp` = ISO8601 字符串
+     - `deviceInfo` from 初始化采集
+     - `eventParams`、`customTags` from 调用
+   - 事件入内存队列 + 异步持久化保存。
+3. 缓存与发送策略
+   - 存储：
+     - SQLite / KV + 索引；
+     - 最大缓存条数：`maxCacheSize`，超限则删除最旧事件。
+   - 发送：
+     - 定时器触发 flush；
+     - 队列长度 >= `batchSize` 可立即 flush；
+     - 调用 `AddEventListLog` 批量上传；
+     - 如后端明确不支持，可选降级 `AddEventLog`。
+   - 重试：
+     - 网络错误或 5xx 重试，最多 `maxRetryCount`，指数退避；
+     - 4xx 视为业务失败，不重试，直接丢弃该批，并记录错误（日志）。
+4. 安全与稳定
+   - endpoint 必须为 HTTPS；
+   - 预留请求 header 扩展（签名 / 时间戳 / nonce）。
+   - 所有 IO 和网络在后台线程 / async，不阻塞 UI；
+   - 所有异常在 SDK 内部捕获，不向上抛出导致崩溃。
+
+### 4.3 开发要求
+
+通用：
+
+- 核心逻辑单元测试覆盖率 ≥ 80%（事件构造、缓存、上传、重试）。
+- 使用统一的日志前缀（例如 `[AnalyticsSDK]`）。
+- API 文档齐全，含参数说明和示例代码。
+
+Flutter：
+
+- 不引入过重依赖，确保兼容常见 Flutter stable 版本；
+- 高频 track 时（例如 10 次/秒）主 Isolate 无明显卡顿。
+
+Android：
+
+- 支持主流 Android 版本（按照公司基线，例如 API 21+）；
+- 在 debug 版开启详细日志，release 版关闭。
+
+iOS：
+
+- 支持主流 iOS 版本（例如 iOS 12+）；
+- 保证在 App 退后台 / 杀进程前能尽可能 flush。
+
+### 4.4 Phase 1 验收标准
+
+功能：
+
+- 三端均可：
+  `init → setUser → track → flush` 全流程成功；
+- 离线：
+  - 断网时事件成功写入本地；
+  - 恢复网络后自动/手动 flush，可在后端查看到补发数据；
+- 批量：
+  - 实际调用 `AddEventListLog`；
+  - 后端数据结构与约定一致（字段正确）。
+
+稳定：
+
+- 连续调用 track 1 万次以内无崩溃；
+- 事件缓存满时按预期丢弃最旧数据，不影响业务。
+
+安全：
+
+- 所有请求通过 HTTPS；
+- 默认不输出包含 userInfo 的敏感日志（除非显式 enableDebug）。
+
+文档：
+
+- 各端接入指南（集成、初始化、上报示例）；
+- 一份基础 FAQ（常见错误、排查方式）。
+
+------
+
+## Phase 2：可维护性 + 配置化 + 调试能力
+
+### 5.1 目标
+
+- 降低埋点维护成本；
+- 支持通过后端配置管理事件和维度；
+- 提供调试和校验工具，提高埋点正确率。
+
+### 5.2 能力范围
+
+1. 利用 `GetSystemAllDimInfo` 下发配置
+
+- SDK 在 init 后或定期调用：
+  - 获取 `systemInfo`、`systemEventTypes`、`systemCustonTas`；
+- 转换成本地配置对象，缓存到本地（带 version / lastModified）：
+
+ts
+
+```
+type EventDefinition = {
+  eventCode: string
+  eventName: string
+  description?: string
+}
+
+type TagDefinition = {
+  tagName: string
+  tagType: string    // string/int/bool/enum
+  isRequired: boolean
+  description?: string
+}
+```
+
+- 失败不影响事件发送（降级为无配置模式）。
+
+1. 事件校验
+
+- 在 `track` 时（主要在 debug 模式启用）：
+  - 校验 `eventType` 是否存在于 `systemEventTypes`；
+  - 使用 `systemCustonTas` 检查：
+    - 必填 tag 是否存在；
+    - 类型是否匹配（尝试容错转换）。
+- 错误处理：
+  - Debug 模式：
+    - 在日志中详细打印：未注册事件、缺失字段、类型错误；
+    - 可配置：是否禁止发送这类事件。
+  - Release 模式：
+    - 仍发送，但在 `customTags` 中附加：
+      - `_sdk_invalid_event`
+      - `_sdk_missing_tags`
+      - `_sdk_type_error_fields`
+
+1. 调试工具
+
+- 日志级：
+  - `setDebug(true)` 时：
+    - 打印每条事件的 JSON；
+    - 打印发送结果（状态码、错误内容）。
+- Demo 内调试页面（建议）：
+  - 支持：
+    - 查看缓存事件数量 / 最近 N 条事件摘要；
+    - 按钮触发 flush。
+
+1. 队列与策略优化（基本）
+
+- 事件过期时间（例如默认 7 天）；
+- 网络状态感知（原生）：
+  - Wi-Fi 下更高频 / 大批次；
+  - 蜂窝网络下减少频率 / 批量。
+
+### 5.3 开发要求
+
+- 新增模块：
+  - `ConfigManager`：拉取与缓存后端维度配置；
+  - `Validator`：统一事件校验逻辑。
+- 兼容 Phase 1：
+  - 未取到配置时，一切行为回退到 Phase 1 模式；
+- 增加测试：
+  - 事件存在 / 不存在；
+  - 必填字段缺失；
+  - 类型错误时的行为。
+
+### 5.4 Phase 2 验收标准
+
+功能：
+
+- 初始化后，可以成功调用 `GetSystemAllDimInfo` 并本地缓存；
+- 在 debug 模式下：
+  - 未配置的 `eventType` 调用时有明确日志提示；
+  - 缺失必填 tag / 类型错误能被检测并打印提示。
+
+调试体验：
+
+- 开发可以在本地：
+  - 看到完整事件 JSON；
+  - 根据提示迅速发现埋点错漏。
+
+可维护性：
+
+- 后端新增事件配置（systemEventTypes 中新增）后，不发版即可在客户端调用新事件；
+- 对关键事件，可以通过配置 + SDK 校验，显著减少埋点错误。
+
+------
+
+## Phase 3：可观测性 + 动态策略 + 插件化
+
+### 6.1 目标
+
+- 让 SDK 自身「可被监控、可被远程控制」；
+- 支持高级使用场景：采样、动态开关、插件扩展。
+
+### 6.2 能力范围
+
+1. SDK 自身监控埋点
+
+- 内部采集 SDK 运行指标（作为特殊事件上报）：
+  - 发送成功计数 / 失败计数 / 重试次数；
+  - 平均延迟；
+  - 队列当前长度 / 溢出丢弃数；
+- 周期性上报（如每 N 分钟一次）。
+
+1. 动态策略控制
+
+- 通过配置（可在 `GetSystemAllDimInfo` 扩展，或单独接口）下发策略，如：
+
+jsonc
+
+```
+{
+  "enabled": true,
+  "eventSettings": {
+    "EVENT_A": { "enabled": true, "sampleRate": 1.0 },
+    "EVENT_B": { "enabled": false, "sampleRate": 0.0 },
+    "EVENT_C": { "enabled": true, "sampleRate": 0.1 }
+  }
+}
+```
+
+- SDK 在 `track` 时：
+  - 若事件被标记 `enabled=false` → 直接丢弃；
+  - 若 `sampleRate < 1` → 按采样率丢弃部分事件（哈希或随机）。
+
+1. 插件 / 拦截器机制
+
+- 接口示例（通用设计）：
+
+ts
+
+```
+interface EventInterceptor {
+  beforeSend(event: Event): Event | null | Promise<Event | null>
+  afterSend(event: Event, result: SendResult): void | Promise<void>
+}
+```
+
+- SDK 提供：
+  - `registerInterceptor(interceptor)` / `addInterceptor` 方法；
+  - 内置拦截器：debug 打印、公共字段填充等。
+
+典型用途：
+
+- 业务统一追加自定义 `customTags`（如租户 ID、业务线 ID）；
+- 将部分发送失败事件写入本地日志，便于问题排查。
+
+1. 版本管理
+
+- 事件级 schemaVersion 预留：
+  - 在 `customTags` 或 `eventParams` 中加入 `_schema_version`。
+- SDK 版本上报：
+  - 每条事件默认携带 `_sdk_version` 和 `_platform`，便于后端统计版本分布。
+
+### 6.3 开发要求
+
+- 性能：
+  - 插件链路运行开销可控（单条事件处理在毫秒级以内）；
+- 隔离：
+  - 单个插件抛出的异常不会影响主流程和其他插件；
+- 文档：
+  - 清晰说明策略配置字段及含义；
+  - 插件开发 & 使用指南。
+
+### 6.4 Phase 3 验收标准
+
+- 自监控：
+  - 后端可以查看 SDK 的发送成功率、失败率、队列长度等；
+- 动态控制：
+  - 通过配置关闭某个 eventType 后，客户端不再上报该事件；
+  - 调整 sampleRate 后，事件量按预期变化；
+- 插件：
+  - 样例插件能实现：
+    - 自动附加业务 tag；
+    - 记录失败事件到本地日志。
+
+------
+
+这版方案已经：
+
+- 明确：Flutter 为独立纯 Dart SDK，与 Android/iOS 平行；
+- 统一：三端对外 API、数据结构、阶段目标和验收标准；
+- 预留：维度配置、校验、动态策略、插件机制的扩展空间。

+## 一、统一模型 & 规范（细化）
+
+### 1.1 SDKConfig 统一规范
+
+所有端保持字段一致，命名按各端风格适配：
+
+jsonc
+
+```
+{
+  "systemCode": "OA_APP",
+  "endpointBaseUrl": "https://host/api/ExternalEventlogs",
+  "clientType": 1,            // 1 Android, 2 iOS, 3 Flutter
+  "enableDebug": false,
+
+  "batchSize": 20,            // 单次最多上传条数
+  "flushInterval": 15,        // 秒，定时 flush 间隔
+  "maxCacheSize": 5000,       // 本地缓存最大事件条数
+  "maxRetryCount": 3,         // 最大重试次数
+
+  "connectTimeout": 5000,     // ms
+  "readTimeout": 5000         // ms
+
+  // 预留，将来可扩：
+  // "globalTags": { "appVersion": "1.0.0", "channel": "official" }
+}
+```
+
+### 1.2 Event 内部字段规范
+
+统一内部 Event 类字段（各端自行建模）：
+
+ts
+
+```
+class Event {
+  String id;                 // 本地ID/主键
+  String systemCode;
+  String eventType;
+
+  UserInfo? userInfo;
+  int clientType;
+  int clientTimestamp;       // ms
+  String timestamp;          // ISO8601
+
+  DeviceInfo deviceInfo;
+
+  Map<String, dynamic>? eventParams;
+  Map<String, dynamic>? customTags;
+
+  int retryCount;            // 已重试次数
+  DateTime createTime;
+}
+```
+
+------
+
+## 二、Phase 1：可用 + 稳定（细化到类 & 表）
+
+### 2.1 通用逻辑（跨端统一）
+
+#### 2.1.1 发送流程（时序）
+
+1. App 调用 `Analytics.init(config)`
+2. SDK：
+   - 保存 config
+   - 采集 DeviceInfo
+   - 初始化 Storage
+   - 启动定时任务（每 flushInterval 秒执行 flush）
+3. App 调用 `Analytics.setUser(...)`（可多次）
+4. App 调用 `Analytics.track(eventType, {...})`：
+   - 构造 Event
+   - 持久化入库
+   - 如果缓存条数 ≥ batchSize：启动一次 flush
+5. flush 流程：
+   - 从存储取前 `batchSize` 条事件；
+   - 调用 `AddEventListLog`：
+     - 成功：删除这些事件；
+     - 网络错/5xx：更新 retryCount，重排队，按指数退避调度；
+     - 4xx：记录日志，删除这些事件（视为「业务不可重试」）。
+
+#### 2.1.2 本地表结构（推荐统一）
+
+SQLite 表 `events`：
+
+sql
+
+```
+CREATE TABLE events (
+  id INTEGER PRIMARY KEY AUTOINCREMENT,
+  payload TEXT NOT NULL,          -- 事件完整 JSON
+  retry_count INTEGER NOT NULL DEFAULT 0,
+  create_time INTEGER NOT NULL    -- ms since epoch
+);
+```
+
+索引：
+
+sql
+
+```
+CREATE INDEX idx_events_create_time ON events(create_time);
+```
+
+> Flutter 可用 sqflite 按此结构实现。
+
+------
+
+### 2.2 Flutter SDK（Dart 独立实现）
+
+#### 2.2.1 目录结构建议
+

+      scheduler.dart
+    util/
+      logger.dart
+      time_util.dart
+```
+
+#### 2.2.2 关键类职责
+
+- `Analytics`（facade）
+  - 静态方法：`init / track / setUser / setDeviceInfo / flush / setDebug`
+  - 内部持有单例 `AnalyticsCore`
+- `AnalyticsCore`
+  - 字段：
+    - `AnalyticsConfig _config`
+    - `UserInfo? _user`
+    - `DeviceInfo _device`
+    - `EventStorage _storage`
+    - `ApiClient _apiClient`
+    - `Timer? _timer`
+    - `bool _isFlushing`
+  - 方法：
+    - `init(config)`
+    - `setUser`
+    - `setDeviceInfo`
+    - `track(...)`
+    - `flush({bool force = false})`
+- `EventStorage` 接口 + `SqfliteEventStorage` 实现
+  - `Future<void> insert(Event event)`
+  - `Future<List<StoredEvent>> fetchBatch(int limit)`
+  - `Future<void> deleteByIds(List<int> ids)`
+  - `Future<int> count()`
+  - `Future<void> trimToMaxSize(int maxSize)`
+- `ApiClient`
+  - `Future<bool> sendBatch(List<Event> events)`
+    - POST `/AddEventListLog`，Body 为数组；
+    - 成功返回 true，失败 false 或抛异常。
+  - （可选）单条 `sendSingle(Event)` 作降级方案。
+- `Scheduler`
+  - 内含 `Timer.periodic`；
+  - 每次 tick 调用 `core.flush()`；
+  - 通过 `_isFlushing` 防并发。
+
+#### 2.2.3 技术要求（Flutter）
+
+- 使用 `async/await`，所有 IO 非阻塞；
+- `Analytics` 所有对外 API 均返回 `Future`（init / track / flush）便于业务 await；
+- 避免 `Timer` 仍在运行却对象已销毁：在必要时提供 `dispose`（可选）。
+

+
+#### 2.3.2 关键实现要点
+
+- Room 表结构：
+
+kotlin
+
+```
+@Entity(tableName = "events")
+data class EventEntity(
+  @PrimaryKey(autoGenerate = true) val id: Long = 0,
+  @ColumnInfo(name = "payload") val payload: String,
+  @ColumnInfo(name = "retry_count") val retryCount: Int = 0,
+  @ColumnInfo(name = "create_time") val createTime: Long = System.currentTimeMillis()
+)
+```
+
+- DAO:
+
+kotlin
+
+```
+@Dao
+interface EventDao {
+  @Insert
+  suspend fun insert(entity: EventEntity)
+
+  @Query("SELECT * FROM events ORDER BY create_time ASC LIMIT :limit")

+
+  @Query("DELETE FROM events WHERE id IN (:ids)")
+  suspend fun deleteByIds(ids: List<Long>)
+
+  @Query("SELECT COUNT(*) FROM events")
+  suspend fun count(): Int
+
+  @Query("""
+    DELETE FROM events WHERE id IN (
+      SELECT id FROM events ORDER BY create_time ASC LIMIT 
+        (SELECT MAX(0, COUNT(*) - :maxSize) FROM events)
+    )
+  """)
+  suspend fun trimToMaxSize(maxSize: Int)
+}
+```
+
+- 调度：
+  - 使用 `CoroutineScope(SupervisorJob() + Dispatchers.IO)`；
+  - `FlushScheduler` 用 `delay` 或 `TickerChannel` 实现周期任务；
+  - 使用 `Mutex` 或 flag 控制“单一 flush”。

+
+text
+
+```
+AnalyticsSDK/
+  Analytics.swift              // Facade
+  Config/
+    AnalyticsConfig.swift
+  Model/

+    FlushScheduler.swift
+  Util/
+    Logger.swift
+    TimeUtil.swift
+```
+
+#### 2.4.2 关键实现要点
+
+- 存储：
+  - 使用 SQLite（用 FMDB/GRDB 等封装，或自己写简单 wrapper）；
+- 网络：
+  - URLSession + Codable 序列化；
+- 定时：
+  - `Timer.scheduledTimer` 或 `DispatchSourceTimer`；
+- 生命周期：
+  - 订阅 `UIApplication` 通知，在进入后台前调用 `flush()`。
+
+------
+
+### 2.5 Phase 1 验收 checklist（落地用）
+
+-  三端提供初始化、用户设置、事件上报、flush API；
+-  本地缓存可持久化，多次启动数据不丢；
+-  断网 → 上报 → 恢复，事件能补发到后端；
+-  压测 10K 条事件，上报成功率可接受（> 99%，无 crash）；
+-  业务方集成 Demo App 并通过功能测试。
+
+------
+
+## 三、Phase 2：配置化 + 校验 + 调试（细化）
+
+### 3.1 新增数据结构
+
+#### 3.1.1 维度配置缓存（本地）
+
+以通用视角描述，三端类似：
+
+ts
+
+```
+class SystemDimInfo {
+  SystemInfo systemInfo;
+  List<EventDefinition> eventDefinitions;
+  List<TagDefinition> tagDefinitions;
+  DateTime lastFetchedAt;
+  String? version;   // 从后端 header 或 body 获得
+}
+```
+
+- `EventDefinition` 来自 `systemEventTypes`：
+  - `eventCode`, `eventName`, `description`
+- `TagDefinition` 来自 `systemCustonTas`：
+  - `tag_name`, `tag_type`, `is_required`, `description`
+
+本地可存储在：
+
+- Flutter：sqflite/hive 单独表/box；
+- Android：Room 新表 `config`;
+- iOS：UserDefaults / SQLite。
+
+### 3.2 ConfigManager / DimensionManager
+
+职责：
+
+- 拉取 `GetSystemAllDimInfo(system_code)`；
+- 解析为 `SystemDimInfo`；
+- 序列化到本地；
+- 提供只读访问 API 给 Validator。
+
+调用时机：
+
+- init 成功后异步拉取；
+- 间隔 N 小时（如 12 / 24h）自动刷新；
+- 提供 `forceRefresh()` 接口（仅 debug 使用）。
+
+### 3.3 Validator 详细逻辑
+
+以伪代码描述：
+
+ts
+
+```
+validateEvent(event: Event): ValidationResult {
+  let result = new ValidationResult()
+
+  // 1. eventType 是否在配置中
+  if (!config.hasEvent(event.eventType)) {
+    result.addError("UNKNOWN_EVENT_TYPE")
+  }
+
+  // 2. 校验必填 tag（customTags）
+  let requiredTags = config.getRequiredTags()
+  for (tag in requiredTags) {
+    if (!event.customTags?.containsKey(tag.name)) {
+      result.addWarning("MISSING_REQUIRED_TAG", tag.name)
+    }
+    else {
+      // 3. 简单类型校验
+      if (!typeMatch(event.customTags[tag.name], tag.type)) {
+        result.addWarning("TYPE_MISMATCH", tag.name)
+      }
+    }
+  }
+
+  return result
+}
+```
+
+- Debug 模式：
+  - 所有 `errors` + `warnings` 打到日志；
+  - 可选策略：有 error 的事件不发送。
+- Release 模式：
+  - 仍发送，但将错误信息 encode 到 `customTags._sdk_validation` 中。
+
+### 3.4 调试支持细化
+
+#### 3.4.1 日志规范
+
+统一日志前缀与级别：
+
+- `[AnalyticsSDK][DEBUG] ...`
+- `[AnalyticsSDK][ERROR] ...`
+
+在 debug 打开时：
+
+- 打印：
+  - 初始化配置；
+  - 事件构造后的 JSON；
+  - 每次发送的批次大小、结果状态码；
+  - 校验结果（仅 debug）。
+
+#### 3.4.2 Demo 调试面板（可选但推荐）
+
+Flutter / 原生各自 Demo App 中：
+
+- 提供一个 Debug 页面：
+  - 显示当前缓存条数；
+  - 最近 20 条事件简要信息（id、eventType、createTime、是否校验通过）；
+  - 按钮：`Flush Now`，调用 `Analytics.flush()`。
+
+------
+
+## 四、Phase 3：监控 + 动态策略 + 插件（细化）
+
+### 4.1 SDK 自监控事件设计
+
+定义一批内部保留事件（只你们自己分析用）：
+
+- `SDK_METRICS_SEND`：
+  - 字段：
+    - `sentCount`
+    - `failedCount`
+    - `retryCount`
+    - `avgLatencyMs`
+- `SDK_METRICS_QUEUE`：
+  - 字段：
+    - `queueSize`
+    - `droppedEvents`
+
+实现：
+
+- 在 SDK 内部维护计数器；
+- 每隔 M 分钟（如 10 分钟）封装成 Event，正常通过日志接口上报。
+
+### 4.2 策略配置结构
+
+可通过扩展 `GetSystemAllDimInfo` 或另建接口下发 JSON，例如：
+
+jsonc
+
+```
+{
+  "sdkStrategy": {
+    "enabled": true,
+    "defaultSampleRate": 1.0,
+    "eventSettings": {
+      "PAGE_VIEW": { "enabled": true, "sampleRate": 0.2 },
+      "DEBUG_EVENT": { "enabled": false, "sampleRate": 0.0 }
+    }
+  }
+}
+```
+
+SDK 行为：
+
+- 加载策略后：
+  - `if !strategy.enabled`：`track` 直接返回，不做任何事情（紧急开关）。
+  - 查找具体 eventType 的策略：
+    - `enabled=false` → 直接丢；
+    - `sampleRate<1` → 按 sampleRate 随机采样（或使用 eventId hash）。
+
+### 4.3 插件机制设计
+
+通用接口（以伪代码）：
+
+ts
+
+```
+interface EventInterceptor {
+  beforeSend(event: Event): Event | null | Promise<Event | null>
+  afterSend(event: Event, result: SendResult): void | Promise<void>
+}
+```
+
+- SDK 内部维护 `List<EventInterceptor>`；
+- 在真正上传前，按顺序调用 `beforeSend`：
+  - 任一返回 null → 事件被拦截，标记为丢弃；
+- 上传结束后，按顺序调用 `afterSend`。
+
+错误隔离：
+
+ts
+
+```
+for interceptor in interceptors:
+  try {
+    event = interceptor.beforeSend(event)
+  } catch (e) {
+    log.warn("interceptor error: ", e)
+  }
+```
+
+示例内置插件：
+
+- DebugInterceptor：
+  - beforeSend 打印事件 JSON（受 debug 开关控制）；
+- CommonTagsInterceptor：
+  - 自动在 customTags 注入 `_sdk_version`、`_platform` 等。
+
+------
+
+## 五、落地实施建议（简短）
+
+### 5.1 Phase 1 任务拆分（多端并行）
+
+- 架构公共约定 & 协议定义（1～2 天）
+- Flutter SDK Phase 1 实现（约 5～10 个工作日）
+- Android SDK Phase 1 实现（约 5～10 天）
+- iOS SDK Phase 1 实现（约 5～10 天）
+- 后端联调 & Demo App 验证（3～5 天）
+
+### 5.2 后续 Phase 2/3 可以按版本迭代
+
+- v1.x：只做 Phase 1，快速在一个业务 App 落地；
+- v2.x：引入配置拉取 + 校验 + Debug 面板；
+- v3.x：按需要逐步加上策略控制 & 插件。

+# Flutter 埋点 SDK 设计方案（独立 Dart 实现）
+
+## 1. 概述
+
+### 1.1 背景
+
+为企业内部 OA / 教育等应用统一建设埋点能力，当前后端已提供日志上报接口：
+
+- `GET  /api/ExternalEventlogs/GetSystemAllDimInfo`
+- `POST /api/ExternalEventlogs/AddEventListLog`
+- `POST /api/ExternalEventlogs/AddEventLog`
+
+需要基于上述接口，开发一个独立的 Flutter 埋点 SDK（纯 Dart 实现），并规划三阶段能力演进。
+
+### 1.2 目标
+
+- 开发 Flutter 独立埋点 SDK 包（例如：`company_analytics_sdk`）。
+- 提供统一的初始化、事件上报、缓存与批量上报能力。
+- 三阶段演进目标：
+  - Phase 1：可用性 + 安全稳定性。
+  - Phase 2：可维护性 + 配置化 + 调试。
+  - Phase 3：可观测性 + 动态策略 + 插件化。
+
+---
+
+## 2. 统一模型与对外 API
+
+### 2.1 统一事件数据结构（对齐后端）
+
+```jsonc
+{
+  "system_code": "string",
+  "eventType": "string",
+  "userInfo": {
+    "userId": 0,
+    "userName": "string",
+    "account": "string"
+  },
+  "clientType": 1,
+  "clientTimestamp": 0,
+  "timestamp": "2026-01-26T08:29:44.734Z",
+  "deviceInfo": {
+    "os": "string",
+    "model": "string",
+    "screenResolution": "string"
+  },
+  "eventParams": {
+    // 事件上下文
+  },
+  "customTags": {
+    // 业务维度
+  }
+}
+```
+
+### 2.2 Flutter SDK 对外 Facade API
+
+```dart
+class Analytics {
+  static Future<void> init(AnalyticsConfig config);
+
+  static Future<void> track(
+    String eventType, {
+    Map<String, dynamic>? eventParams,
+    Map<String, dynamic>? customTags,
+    int? timestamp, // ms
+  });
+
+  static Future<void> setUser(UserInfo? userInfo);
+
+  static Future<void> setDeviceInfo(DeviceInfo deviceInfo);
+
+  static Future<void> flush();
+
+  static void setDebug(bool enabled);
+
+  // Phase 3
+  static void addInterceptor(AnalyticsInterceptor interceptor);
+}
+```
+
+### 2.3 SDKConfig 统一规范
+
+```dart
+class AnalyticsConfig {
+  final String systemCode;
+  final String endpointBaseUrl;   // https://host/api/ExternalEventlogs
+  final int clientType;           // 1=Android, 2=iOS, 3=Flutter
+  final bool enableDebug;
+
+  final int batchSize;            // 默认 20
+  final int flushInterval;        // 秒，默认 15
+  final int maxCacheSize;         // 默认 5000
+  final int maxRetryCount;        // 默认 3
+
+  final Duration connectTimeout;  // 默认 5s
+  final Duration readTimeout;     // 默认 5s
+
+  const AnalyticsConfig({
+    required this.systemCode,
+    required this.endpointBaseUrl,
+    required this.clientType,
+    this.enableDebug = false,
+    this.batchSize = 20,
+    this.flushInterval = 15,
+    this.maxCacheSize = 5000,
+    this.maxRetryCount = 3,
+    this.connectTimeout = const Duration(seconds: 5),
+    this.readTimeout = const Duration(seconds: 5),
+  });
+}
+```
+

+```
+
+### 3.2 核心模型
+
+UserInfo：
+
+```dart
+class UserInfo {
+  final int? userId;
+  final String? userName;
+  final String? account;
+
+  const UserInfo({this.userId, this.userName, this.account});
+
+  Map<String, dynamic> toJson() => {
+        'userId': userId,
+        'userName': userName,
+        'account': account,
+      }..removeWhere((k, v) => v == null);
+}
+```
+
+DeviceInfo：
+
+```dart
+class DeviceInfo {
+  final String os;
+  final String model;
+  final String screenResolution;
+
+  const DeviceInfo({
+    required this.os,
+    required this.model,
+    required this.screenResolution,
+  });
+
+  Map<String, dynamic> toJson() => {
+        'os': os,
+        'model': model,
+        'screenResolution': screenResolution,
+      };
+}
+```
+
+Event：
+
+```dart
+class Event {
+  final String systemCode;
+  final String eventType;
+  final UserInfo? userInfo;
+  final int clientType;
+  final int clientTimestamp;
+  final String timestamp;
+  final DeviceInfo deviceInfo;
+  final Map<String, dynamic>? eventParams;
+  final Map<String, dynamic>? customTags;
+  final DateTime createTime;
+  final int retryCount;
+
+  Event({
+    required this.systemCode,
+    required this.eventType,
+    required this.userInfo,
+    required this.clientType,
+    required this.clientTimestamp,
+    required this.timestamp,
+    required this.deviceInfo,
+    required this.eventParams,
+    required this.customTags,
+    required this.createTime,
+    this.retryCount = 0,
+  });
+
+  Map<String, dynamic> toJson() => {
+        'system_code': systemCode,
+        'eventType': eventType,
+        'userInfo': userInfo?.toJson(),
+        'clientType': clientType,
+        'clientTimestamp': clientTimestamp,
+        'timestamp': timestamp,
+        'deviceInfo': deviceInfo.toJson(),
+        'eventParams': eventParams,
+        'customTags': customTags,
+      };
+}
+```
+
+StoredEvent：
+
+```dart
+class StoredEvent {
+  final int id;
+  final Event event;
+  final int retryCount;
+  final DateTime createTime;
+
+  StoredEvent({
+    required this.id,
+    required this.event,
+    required this.retryCount,
+    required this.createTime,
+  });
+}
+```
+
+---
+
+## 4. Phase 1：可用性 + 安全稳定性
+
+### 4.1 功能范围
+
+- SDK 初始化：
+  - 校验 `AnalyticsConfig`；
+  - 自动采集 `DeviceInfo`；
+  - 初始化本地 SQLite 存储；
+  - 启动定时 flush 任务。
+- 事件上报：
+  - 构造 Event（system_code、userInfo、deviceInfo、时间戳等）；
+  - 异步写入本地队列（SQLite）。
+- 批量上传：
+  - 定时 & 条数触发 flush；
+  - 调用 `POST /AddEventListLog`；
+  - 处理重试 / 失败 / 删除等逻辑。
+- 安全：
+  - endpoint 强制 HTTPS；
+  - 预留 header 扩展（签名等）。
+
+### 4.2 本地存储设计（Sqflite）
+
+表结构：
+
+```sql
+CREATE TABLE events (
+  id INTEGER PRIMARY KEY AUTOINCREMENT,
+  payload TEXT NOT NULL,
+  retry_count INTEGER NOT NULL DEFAULT 0,
+  create_time INTEGER NOT NULL
+);
+
+CREATE INDEX idx_events_create_time ON events(create_time);
+```
+
+接口：`EventStorage`
+
+```dart
+abstract class EventStorage {
+  Future<void> init();
+  Future<int> insert(Event event);
+  Future<List<StoredEvent>> fetchBatch(int limit);
+  Future<void> deleteByIds(List<int> ids);
+  Future<int> count();
+  Future<void> trimToMaxSize(int maxSize);
+  Future<void> updateRetryCount(int id, int retryCount);
+}
+```
+
+使用 `SqfliteEventStorage` 具体实现。
+
+### 4.3 网络层 ApiClient
+
+- 基于 `dio` 或 `http` 实现：
+  - `sendBatch(List<Event> events)` 调用 `/AddEventListLog`。
+- 超时控制：使用 `config.connectTimeout` / `readTimeout`。
+
+### 4.4 核心逻辑 AnalyticsCore
+
+职责：
+
+- 保存配置、用户状态、设备信息。
+- `track`：构造 Event、写入存储、触发 flush。
+- `flush`：从本地取批量事件，调用 ApiClient，上报异常处理和重试。
+
+关键点：
+
+- 使用 `_isFlushing` 标志防止并发 flush；
+- 使用 `Scheduler`（Timer.periodic）实现周期 flush；
+- 所有 IO 调用 async/await，避免阻塞 UI。
+
+### 4.5 Phase 1 验收标准（Flutter）
+
+- 功能：
+  - Demo 中完成初始化、用户设置、事件上报、flush；
+  - 断网时事件写入本地，恢复网络后自动/手动 flush 成功。
+- 稳定性：
+  - 高频 `track`（10 次/秒，5 分钟）无 crash、无明显卡顿。
+- 安全：
+  - 所有请求走 HTTPS；
+  - 默认不打印 userInfo 等敏感数据（除非 debug=true）。
+- 文档：
+  - 接入文档 + 示例代码。
+
+---
+
+## 5. Phase 2：配置化 + 校验 + 调试
+
+### 5.1 配置下发（GetSystemAllDimInfo）
+
+- Flutter SDK 调用：
+  - `GET /GetSystemAllDimInfo?system_code=xxx`
+- 解析为：
+  - `SystemInfo`
+  - `EventDefinition` 列表（来自 `systemEventTypes`）
+  - `TagDefinition` 列表（来自 `systemCustonTas`）
+
+本地缓存为 `SystemDimInfo`（可存 SQLite / hive / SharedPreferences）。
+
+### 5.2 ConfigManager
+
+- 负责：
+  - 首次 init 后拉取配置；
+  - 定期刷新；
+  - 提供当前配置给 Validator 使用。
+
+### 5.3 Validator 事件校验
+
+- 校验点：
+  - `eventType` 是否在配置中存在；
+  - 必填 tag（来自 `TagDefinition.isRequired`）是否存在于 `customTags`；
+  - 简单类型检查（int/bool/string）。
+
+策略：
+
+- Debug 模式：
+  - 日志详细提示未知事件、缺失字段、类型错误；
+  - 可配置是否阻断发送。
+- Release 模式：
+  - 不阻断，错误信息写入 `customTags._sdk_validation`。
+
+### 5.4 调试能力
+
+- 日志：
+  - `Logger` 控制 debug 开关；
+  - 打印事件 JSON、发送结果、校验结果。
+- Demo 调试界面（推荐）：
+  - 展示缓存事件数量 / 最近 N 条；
+  - 提供“立即 flush”按钮。
+
+---
+
+## 6. Phase 3：可观测性 + 策略 + 插件
+
+### 6.1 SDK 自监控
+
+- 内部统计：
+  - 发送成功次数 / 失败次数；
+  - 重试次数；
+  - 队列长度 / 溢出丢弃个数。
+- 周期上报为特殊事件（如 `SDK_METRICS_SEND`/`SDK_METRICS_QUEUE`）。
+
+### 6.2 动态策略控制
+
+- 从配置中下发策略字段，例如：
+
+```jsonc
+{
+  "sdkStrategy": {
+    "enabled": true,
+    "defaultSampleRate": 1.0,
+    "eventSettings": {
+      "PAGE_VIEW": { "enabled": true, "sampleRate": 0.2 },
+      "DEBUG_EVENT": { "enabled": false, "sampleRate": 0.0 }
+    }
+  }
+}
+```
+
+- `track` 时根据策略：
+  - 全局关停：直接丢弃全部事件；
+  - 单事件关闭：丢弃该 eventType；
+  - 按 sampleRate 采样丢弃部分事件。
+
+### 6.3 插件（拦截器）机制
+
+接口示例：
+
+```dart
+abstract class AnalyticsInterceptor {
+  Future<Event?> beforeSend(Event event) async => event;
+  Future<void> afterSend(Event event, bool success) async {}
+}
+```
+
+- 在 `AnalyticsCore` 中注册多个拦截器；
+- flush 时在实际发送前后调用；
+- 捕获拦截器内部异常，不影响主流程。
+
+内置拦截器示例：
+
+- `DebugInterceptor`：打印事件详细信息；
+- `CommonTagsInterceptor`：为所有事件追加 `_sdk_version`、`_platform` 等 tag。

+- [x] 基础单测已存在（配置校验、事件序列化/反序列化）
+- [x] `EventStorage` 行为测试已覆盖（trim、fetchRecent、retryCount 更新等契约测试）
+- [x] `AnalyticsCore.track/flush` 成功与失败重试路径测试已覆盖
+- [x] 已完成 mock 集成测试与压力测试（断网恢复补发、track 1 万次稳定性）
+
+------
+
+## 三、Phase 2 开发任务（配置化 + 校验 + 调试）
+
+### 1. 配置模型 & 持久化
+
+- [x] 定义 `SystemInfo / EventDefinition / TagDefinition / SystemDimInfo`
+- [x] 使用 sqflite 同库缓存配置（表：`config_cache`）
+- [x] 已实现 `saveSystemDimInfo / loadSystemDimInfo`
+
+### 2. ConfigManager
+
+- [x] 已实现 `ConfigManager`（持有 `currentConfig`、支持缓存加载与拉取）
+- [x] 已接入 `GET /GetSystemAllDimInfo?system_code=...`
+- [x] 已在 `AnalyticsCore.init` 中异步拉取（失败不影响埋点）
+- [x] 周期刷新已补齐（定时器按 refreshInterval 拉取）
+
+### 3. Validator（事件校验）
+
+- [x] 已实现 `Validator`（依赖 `ConfigManager`，输出 `ValidationResult`）
+- [x] 已在 `AnalyticsCore.track` 中接入校验并打印 errors/warnings
+- [x] Release 模式已补充校验标记（写入 `_sdk_invalid_event/_sdk_missing_tags/_sdk_type_error_fields`）
+- [x] “严重 error 阻断发送”的策略开关已实现（`blockOnValidationError`）
+
+### 4. 调试增强
+
+- [x] `Logger` 已具备 debug/info/warn/error 级别与 debug 开关
+- [x] 关键路径日志已接入（init/track/flush/validator/config）
+- [x] 已提供 Demo 调试界面（`example/`）
+- [x] Demo 已支持：缓存条数、最近事件摘要、Track Demo Event、Flush Now、Refresh Config
+
+### 5. Phase 2 测试任务
+
+- [x] 配置拉取测试已覆盖（正确/错误 JSON、刷新跳过、缓存保持）
+- [x] 校验行为测试已覆盖（未知事件、缺失必填、类型不匹配）
+- [x] “配置失败不影响发送”的降级路径已覆盖（无配置仍可 track/flush）
+
+------
+
+## 四、Phase 3 开发任务（监控 + 策略 + 插件）
+
+### 1. 自监控埋点
+
+- [x] 已在 `AnalyticsCore` 中增加统计字段（sent/failed/retry/dropped、平均延迟、窗口时间）
+- [x] 已在 flush 成功 / 失败 / 删除 / 丢弃等位置更新计数
+- [x] 已实现指标上报（定时器 + 内部事件 `SDK_METRICS_SEND / SDK_METRICS_QUEUE`）
+- [x] 已提供调试入口：`Analytics.reportMetricsNow()`
+
+### 2. 策略控制（采样与开关）
+
+- [x] 已在 `SystemDimInfo` 中增加策略字段（`SdkStrategy / EventStrategy`）
+- [x] 已在 `ConfigManager` 中解析并缓存策略
+- [x] 已在 `AnalyticsCore.track` 入口接入策略（全局开关 / 事件开关 / 采样率）
+
+### 3. 插件（拦截器）机制
+
+- [x] 已定义接口 `AnalyticsInterceptor`（`beforeSend / afterSend`）
+- [x] 已在 `AnalyticsCore` 中维护拦截器列表并实现 `addInterceptor(...)`
+- [x] 已在 flush 前调用 `beforeSend`（支持返回 null 拦截事件）
+- [x] 已在 flush 后调用 `afterSend`（成功/失败均回调）
+- [x] 已做异常隔离（拦截器异常不会影响主流程）
+- [x] 已内置 `CommonTagsInterceptor`（自动追加 `_sdk_version/_platform`）
+
+### 4. Phase 3 测试任务
+
+- [x] 自监控事件测试已覆盖（`reportMetricsNow` 生成 `SDK_METRICS_*` 事件）
+- [x] 策略测试已覆盖（全局关闭、事件关闭、采样率）
+- [x] 拦截器测试已覆盖（追加 tag、拦截事件、异常隔离、afterSend 回调）
+
+------
+
+## 五、交付物与文档清单
+
+- [x] SDK 源码（Flutter package）
+- [x] 单元测试代码（关键路径已覆盖；覆盖率统计报告需单独产出）
+- [x] 集成 Demo App（示例项目，含 Debug 页面）
+- [x] 文档：README（使用说明 + 调试/拦截器/指标能力）
+- [x] 文档：设计说明（`2.Flutter 埋点 SDK 设计方案（独立 Dart 实现）.md`）

+# yx_tracking_flutter
+
+企业级 Flutter 埋点 SDK（纯 Dart 实现），对齐后端接口：
+
+- `GET /api/ExternalEventlogs/GetSystemAllDimInfo`
+- `POST /api/ExternalEventlogs/AddEventListLog`
+- `POST /api/ExternalEventlogs/AddEventLog`（可选降级）
+
+当前已覆盖 Phase 1 / Phase 2 / Phase 3 的核心能力：初始化、持久化队列、批量上报、配置下发、校验、策略控制、拦截器与 SDK 自监控指标。
+
+## 功能特性
+
+- 统一事件模型，自动补齐公共字段（systemCode、deviceInfo、时间戳等）
+- 本地持久化队列（sqflite），断网可缓存，恢复后补发
+- 批量上报 + 重试退避 + 队列上限裁剪
+- 配置下发（`GetSystemAllDimInfo`）与本地缓存
+- 事件校验（Debug 详细日志，Release 自动标记 `_sdk_*`）
+- 动态策略（全局开关、事件级开关、采样率）
+- 拦截器机制（beforeSend / afterSend，异常隔离）
+- SDK 自监控指标（发送成功/失败/重试/丢弃、队列长度、平均延迟）
+
+## 快速开始
+
+在你的 App 初始化阶段调用：
+
+```dart
+import 'package:yx_tracking_flutter/yx_tracking_flutter.dart';
+
+Future<void> bootstrapAnalytics() async {
+  await Analytics.init(
+    const AnalyticsConfig(
+      systemCode: 'OA_APP',
+      endpointBaseUrl: 'https://your-host/api/ExternalEventlogs',
+      clientType: 3,
+      enableDebug: true,
+    ),
+  );
+}
+```
+
+上报事件：
+
+```dart
+await Analytics.track(
+  'PAGE_VIEW',
+  eventParams: const <String, dynamic>{'page': 'home'},
+  customTags: const <String, dynamic>{'tenantId': 't1'},
+);
+```
+
+手动触发发送：
+
+```dart
+await Analytics.flush(force: true);
+```
+
+## 关键配置项（AnalyticsConfig）
+
+除了文档中的 Phase 1 配置项，还新增了以下能力配置：
+
+- `enableMetrics`：是否启用 SDK 自监控指标（默认 `true`）
+- `metricsReportInterval`：指标上报周期（默认 10 分钟）
+- `blockOnValidationError`：Debug 下遇到校验 error 是否阻断发送（默认 `false`）
+
+所有配置项详见：`lib/src/config/analytics_config.dart`
+
+## 调试与运维能力
+
+调试 API：
+
+```dart
+final count = await Analytics.cachedEventCount();
+final recent = await Analytics.cachedRecentEvents(limit: 20);
+await Analytics.refreshConfig(force: true);
+await Analytics.reportMetricsNow();
+```
+
+## 拦截器（Phase 3）
+
+```dart
+class TenantInterceptor extends AnalyticsInterceptor {
+  @override
+  Future<Event?> beforeSend(Event event) async {
+    final tags = Map<String, dynamic>.from(event.customTags ?? const {});
+    tags['tenantId'] = 't1';
+    return event.copyWith(customTags: tags);
+  }
+}
+
+void setupInterceptors() {
+  Analytics.addInterceptor(TenantInterceptor());
+}
+```
+
+SDK 内置 `CommonTagsInterceptor`，会自动追加：
+
+- `_sdk_version`
+- `_platform`
+
+## 运行示例 Demo
+
+仓库已包含最小调试 Demo：
+
+```bash
+cd example
+flutter run
+```
+
+Demo 提供：缓存条数、最近事件摘要、Track Demo Event、Flush Now、Refresh Config。
+
+## 测试与校验
+
+已通过以下本地校验：
+
+- 根目录：`flutter analyze` / `flutter test`
+- example：`flutter analyze` / `flutter test`
+
+## 参考文档
+
+- 设计方案：`2.Flutter 埋点 SDK 设计方案（独立 Dart 实现）.md`
+- 实施清单：`3.Flutter todo list.md`

+# Launch Screen Assets
+
+You can customize the launch screen with your own desired assets by replacing the image files in this directory.
+
+You can also do it by opening your Flutter project's Xcode project with `open ios/Runner.xcworkspace`, selecting `Runner/Assets.xcassets` in the Project Navigator and dropping in the desired images.
