Add the ability to attach to a Flutter view running in an existing Android app

I don't know if this can be considered as an issue but here is my problem.

I embedded a Flutter screen into an existing Android application, I can start the application smoothly using the plugin, but as the Flutter view isn't the first screen of the app it cannot bind on Flutter until the screen is launched. I tried digging into menus to attach manually the plugin but I didn't find anything. With this I cannot use of the cool features offered by Flutter (Hot Reloading, Platform switch, debugging).

Hot reloading still works when using Flutter with CLI, it binds itself when the screen is launched
