How can one get support fragment manager from ThemedReactContext ?

I'm writing a custom native android library that exposes a support fragment for display. I created a simple view manager on the android side of react in which I return a placeholder layout in createViewInstance and later intend to add the library fragment inside receiveCommand on user action from the react side. However in order to add the fragment to the aforementioned container I cannot get the support fragment manager from the ThemedReactContext obj that I capture in createViewInstance. Doing fooThemedReactContext.getCurrentActivity() yields the deprecated android.app.FragmentManager. How do I get android.support.v4.app.FragmentManager instead in my view manager?

For people on Google that end up here, you can make your activities extends ReactFragmentActivity rather than ReactActivity. That class has getSupportFragmentManager() and all that jazz.

@augustl ReactFragmentActivity is marked as deprecated and will be removed soon, you shouldn't be using it.

As far as I can tell, there's no other way of doing it in 0.56 that I can see, so I thought I'd just mention it here in case anyone else found this issue on Google :)

Any hints for RN 0.60+?
