Flutter使用开源的OpenIM_开发im即时通讯聊天源码

1、获取单聊消息

class MessageController extends GetxController{
  var messages = <Message>[].obs;

  Future getMessage(String uid ) async {
    List<Message> recMessages = await OpenIM.iMManager.messageManager.getHistoryMessageList(
      userID: uid, // 单聊对象的userID  
      groupID: null, // 群聊的组id  
      startMsg: null, // 消息体
      count: 20, // 每次拉取的数量
    );

    for (Message ss in recMessages) {
      debugPrint("获取到的消息：-------${ss.toJson().toString()}");
    }

    messages.value = recMessages;
    return recMessages;
  }
}
