修复了insertMessage时出现的 java long cannot be converted to integer 问题

融云 IM flutter plugin

本文档讲解了如何使用 IM 的 Flutter Plugin，基于融云 iOS/Android 平台的 IMLib SDK

Flutter 官网

融云 iOS 文档集成

融云 Android 文档集成

前期准备

融云官网申请开发者账号

通过管理后台的 "基本信息"->"App Key" 获取 appkey

通过管理后台的 "IM 服务"—>"API 调用"->"用户服务"->"获取 Token"，通过用户 id 获取 IMToken

依赖 IM Flutter plugin

在项目的 pubspec.yaml 中写如下依赖

dependencies:
  flutter:
    sdk: flutter

  rongcloud_im_plugin: ^0.9.3

然后在项目路径执行 flutter packages get 来下载 Flutter Plugin

集成步骤

1.初始化 SDK

RongcloudImPlugin.init(RongAppKey);

2.配置 SDK

2.1 在项目目录创建 `assets` 文件夹，并将 `RCFlutterConf.json` 放入该文件夹

2.2 在项目 `pubspec.yaml` 中的写入下面的配置

assets:
  - assets/RCFlutterConf.json

2.3 代码

String confString = await DefaultAssetBundle.of(context).loadString("assets/RCFlutterConf.json");
Map confMap = json.decode(confString.toString());
RongcloudImPlugin.config(confMap);

3.连接 IM

int rc = await RongcloudImPlugin.connect(RongIMToken);
print('connect result');
print(rc);

API 调用

断开 IM 连接

//needPush 断开连接之后是否需要远程推送
RongcloudImPlugin.disconnect(bool needPush)

发送消息

发送文本消息

onSendMessage() async{
      TextMessage txtMessage = new TextMessage();
      txtMessage.content = "这条消息来自 flutter";
      Message msg = await RongcloudImPlugin.sendMessage(RCConversationType.Private, privateUserId, txtMessage);
      print("send message start senderUserId = "+msg.senderUserId);
  }

发送图片消息

onSendImageMessage() async {
    ImageMessage imgMessage = new ImageMessage();
    imgMessage.localPath = "image/local/path.jpg";
    Message msg = await RongcloudImPlugin.sendMessage(RCConversationType.Private, privateUserId, imgMessage);
    print("send image message start senderUserId = "+msg.senderUserId);
  }

发送结果回调

//消息发送结果回调
    RongcloudImPlugin.onMessageSend = (int messageId,int status,int code) {
      print("send message messsageId:"+messageId.toString()+" status:"+status.toString()+" code:"+code.toString());
    };

媒体消息媒体文件上传进度

//媒体消息（图片/语音消息）上传媒体进度的回调
    RongcloudImPlugin.onUploadMediaProgress = (int messageId,int progress) {
      print("upload media messsageId:"+messageId.toString()+" progress:"+progress.toString());
    };

接收消息

//消息接收回调
    RongcloudImPlugin.onMessageReceived = (Message msg,int left) {
      print("receive message messsageId:"+msg.messageId.toString()+" left:"+left.toString());
    };

历史消息

获取本地历史消息

onGetHistoryMessages() async {
    List msgs = await RongcloudImPlugin.getHistoryMessage(RCConversationType.Private, privateUserId, 0, 10);
    print("get history message");
    for(Message m in msgs) {
      print("sentTime = "+m.sentTime.toString());
    }
  }

获取远端历史消息

RongcloudImPlugin.getRemoteHistoryMessages(1, "1001", 0, 20,(List<Message> msgList,int code) {
      if(code == 0) {
        for(Message msg in msgList) {
          print("getRemoteHistoryMessages  success "+ msg.messageId.toString());
        }
      }else {
        print("getRemoteHistoryMessages error "+code.toString());
      }
    });

插入发出的消息

RongcloudImPlugin.insertOutgoingMessage(RCConversationType.Private, "1001", 10, msgT, 0, (msg,code){
      print("insertOutgoingMessage " + msg.content.encode() + " code " + code.toString());

    });

插入收到的消息

RongcloudImPlugin.insertIncomingMessage(RCConversationType.Private, "1002", "1002", 1, msgT , 0, (msg,code){
      print("insertIncomingMessage " + msg.content.encode() + " code " + code.toString());
    });

删除特定会话消息

RongcloudImPlugin.deleteMessages(RCConversationType.Private, "2002", (int code) {

});

批量删除消息

List<int> mids =  new List();
mids.add(1);
RongcloudImPlugin.deleteMessageByIds(mids, (int code) {

});

会话列表

获取会话列表

onGetConversationList() async {
    List conversationList = await RongcloudImPlugin.getConversationList([RCConversationType.Private,RCConversationType.Group,RCConversationType.System]);

    for(Conversation con in cons) {
      print("conversation latestMessageId " + con.latestMessageId.toString());
    }
  }

删除指定会话

RongcloudImPlugin.removeConversation(RCConversationType.Private, "1001", (success) {
      if(success) {
        print("删除会话成功");
      }
    });

加入聊天室

onJoinChatRoom() {
    RongcloudImPlugin.joinChatRoom("testchatroomId", 10);
  }

加入聊天室回调

//加入聊天室结果回调
    RongcloudImPlugin.onJoinChatRoom = (String targetId,int status) {
      print("join chatroom:"+targetId+" status:"+status.toString());
    };

退出聊天室

onQuitChatRoom() {
    RongcloudImPlugin.quitChatRoom("testchatroomId");
  }

退出聊天室回调

//退出聊天室结果回调
    RongcloudImPlugin.onQuitChatRoom = (String targetId,int status) {
      print("quit chatroom:"+targetId+" status:"+status.toString());
    };

获取聊天室信息

onGetChatRoomInfo() async {
    ChatRoomInfo chatRoomInfo = await RongcloudImPlugin.getChatRoomInfo("testchatroomId", 10, RCChatRoomMemberOrder.Desc);
    print("onGetChatRoomInfo targetId ="+chatRoomInfo.targetId);
  }
