3. 通过服务端 API，获取用户 Token。

App Secret 用于生成数据签名，仅在请求融云服务端 API 接口时使用。

依赖 IM Wrapper Plugin

在项目的 pubspec.yaml 中写如下依赖：

dependencies:
  flutter:
    sdk: flutter
  rongcloud_im_wrapper_plugin: 5.24.5

快速开始

详细的集成步骤、API 使用说明、功能配置等内容，请参考 融云 IMLib Flutter 完整开发文档。

文档包含以下完整内容：

• 初始化 - SDK 初始化和引擎创建
• 连接与断开 - 建立和断开 IM 连接

// 初始化 SDK
RCIMIWEngineOptions options = RCIMIWEngineOptions.create();
RCIMIWEngine engine = await RCIMIWEngine.create(appkey, options);

// 连接 IM 服务
engine.connect(token, timeout);

2. 监听连接状态

engine.onConnected = (int? code, String? userId) {
  if (code == 0) {
    // 连接成功
  }
};

3. 发送和接收消息

// 发送文本消息
RCIMIWTextMessage? textMessage = await engine.createTextMessage(
  conversationType, targetId, channelId, text,
);
engine.sendMessage(textMessage);

// 监听接收消息
engine.onMessageReceived = (
  RCIMIWMessage? message,
  int? left,
  bool? offline,
  bool? hasPackage,
) {
  // 处理接收到的消息
};
