关于flutter:Flutter-集成融云-sdk

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: flutter

rongcloud_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
