原生跳Flutter 回调以及flutter测页面生命周期监测问题

看了flutter 源码 ， 想要 知道这两个 功能现在能实现么 ？感谢各位大佬。
1 .
```
Intent intent = BoostFlutterActivity.withNewEngine().url(pageName.get(path)).params(params)
.backgroundMode(BoostFlutterActivity.BackgroundMode.opaque).build(context);
```
这段代码跳flutter 的时候， 如果不知道 context 是哪个 Activity ， 有办法监听到 flutter侧 pop 时候的回调数据么 ？

2. Flutter 侧 ， 页面 能否监听 到onResume 和 onPage 的 生命周期？

Start at the BoostFlutterActivity.withNewEngine().url(...).params(...).build(context) entry point and trace the native-to-Flutter navigation and pop path. Then inspect the Flutter-side lifecycle integration points; done means documenting whether both requested callbacks are supported and identifying the relevant integration points or limitations.
