Recommended way to update content inside childcontrollers with viewpager/RouterPagerAdapter

Hi, I'm struggling/fail to see how I could update content in the childcontrollers managed through a RouterPagerAdapter/viewpager/Tablayout setup after they have been created (and what would be best practice) .

The questions I have:
- Is it the purpose to get a reference to the controller instance and try to call and update function or should it be done through an eventbus/pub-sub type of setup.

- How can I get a reference to the Controller that is currently active in the viewpager. There's no such thing as getItem() as its based on pageradapter

- There seem to exists methods to get a controller but you need an Id. Should I get it on creation and store it somewhere in order to try to use it later?

- Should I use any update logic inside the children. use viewpager.setoffscreenpagelimit in order to force the full lifecycle all the time.

thanks for your thoughts.

Start with the RouterPagerAdapter and its ViewPager/TabLayout integration, then review how child controllers are created and retained. Done means documenting a recommended way to update child-controller content, obtain the active controller, and handle lifecycle updates without relying on an unspecified offscreen-page limit.
