flutter 集成融云 sdk

前言

1.集成 flutter 融云 sdk ，须要一个稳固的 flutter 环境，能失常的创立和运行我的项目。
2.后期筹备融云官网申请开发者账号
通过治理后盾的 "根本信息"->"App Key" 获取 AppKey
3.通过治理后盾的 "IM 服务"—>"API 调用"->"用户服务"->"获取 Token"，通过用户 id 获取 IMToken
4.我晓得没图是骗不到人的。先放图，大家看一下最终实现的成果。

集成 sdk

  1. 依赖 IM Flutter plugin在我的项目的 pubspec.yaml 中写如下依赖。
dependencies:  flutter:    sdk: flutterrongcloud_im_plugin: ^4.0.3
  1. 而后在我的项目门路执行 flutter packages get 来下载 Flutter Plugin。
  2. 咱们写 2 个 button 和 2 个 text ，别离用来实现 init 和 connect 的事件和状态。

4.初始化 SDK

RongIMClient.init(RongAppKey);

5.连贯 IM

RongIMClient.connect(RongIMToken, (int code, String userId) {  print('connect result ' + code.toString());  EventBus.instance.commit(EventKeys.UpdateNotificationQuietStatus, {});if (code == 31004 || code == 12) {  Navigator.of(context).pushAndRemoveUntil(new MaterialPageRoute(builder: (context) => new LoginPage()), (route) => route == null);} else if (code == 0) {  print("connect userId" + userId);  // 连贯胜利后关上数据库  // _initUserInfoCache();}

全副代码参考
