In following I have

scaffold

with

bodyContent

containing a list (using

LazyColumnFor

) and a

BottomAppBar

....selecting different options in bottom bar causes some state to change and for UI to be recomposed (with content of list updated).....the only issue is that list position remains the same. Is there way I can/should reset that when I select different option? https://github.com/joreilly/BikeShare/blob/master/app/src/main/java/com/surrus/bikeshare/MainActivity.kt

This is what UI looks like right now.....so, in this case for example if I scroll down list, then select Oslo, the data for Oslo is shown in list but I'm at same position in list as I was when viewing Galway list.

One problem at least with that is if I scroll to bottom of longer list and then switch to other one....then nothing is shown.....but in any case I think expectation would be that you'd be at top of new list when you switch

It looks to be a limitation currently? https://kotlinlang.slack.com/archives/CJLTWPH7S/p1595406328132400?thread_ts=1595406328.132400&cid=CJLTWPH7S but I could be mistaken

There is the other list composable, ScrollableColumn that lets you pass in a ScrollState that you can control https://github.com/adrianblancode/Cheddar/blob/28b8620fa2abcaf6b492833b7f3ce8cab01e9c02/feature-storyfeed/src/main/java/co/adrianblan/storyfeed/ui/StoryFeedView.kt#L66
