错误原因
FlutterQqPlugin.java 中的 OneListener 实例多次创建，会导致 QQ SDK 处理错误，只需要在 FlutterQqPlugin.java 中设置一个 OneListener 实例即可，具体改动可见 litang0908@339c118
解决方案
-
git clone这个 repo https://github.com/litang0908/flutter_qq ，此fork自原项目，且做了修复 -
将你自己项目配置的
flutter_qq依赖，改为步骤1中clone的仓库地址
flutter_qq: ^0.0.5
改为
flutter_qq:
path: ../codes/github/flutter_qq/
（注：此处路径为步骤1中clone项目相对位置）
重新执行 flutter pub get 后运行项目即可。
