Hey guys, very new to flutter and have been learning in order to start making pull requests on Github. However its been a while since ive used a non-R programming language so I might be a bit rusty with some concepts.

For reference, the repo i want to help out is Thunder

What im trying to do is cause a page to scroll to the top, when the user presses the bottom navigation bar button for that page.

So it goes PageView, CommunityPage, then PostCardList, which is a class containing a ListView showing the cards and whatever else.

I get that I need to pass one of the scrollControllers up to the main PageView level, and then use the BottomNavigationBar onTap (index) function to call an animateTo on it. But i dont know where, or how i pass the scrollcontroller up a level. When i know how, do i just pass it from the PostCardList class, to the CommunityPage class, to the PageView-level class? Or is there some better way??

Sorry for such a low level question but ive been learning this for like 2 or 3 days and have no experience whatsoever hahaha

Thanks!

    Thanks for the reply! Bit it might be a bit advanced for me at this stage… Do you have any youtube vids or other resources that might help me out with those concepts?
