经断点 发现RongcloudImPlugin.java 中 获取context 为空RCIMFlutterWrapper.getInstance().saveContext(registrar.activity().getApplicationContext());
查找相关资料 发现flutter plugin 在flutter 1.12 release 用了新的api https://flutter.dev/docs/development/packages-and-plugins/plugin-api-migration

你尝试 debug 一下 这个 RongcloudImPlugin 如下代码，应该获取到的 context 是个 null
RCIMFlutterWrapper.getInstance().saveContext(registrar.activity().getApplicationContext());

所以这边可能需要您更换一下 context 的获取方式 registrar.context() 等方法

是的。debug context 为空。需要修改下RongcloudImPlugin代码。考虑到需求暂时放弃flutter 方式实现。使用原生来搞。
