I'm getting this error when I moved a composable to separate fragment This Composable is being rendered inside a 
FragmentContainerView
hosted inside a LinearLayout but sadly I need to use that LinearLayout in the xml, what can be done to make this work?
Copy code
java.lang.IllegalStateException: Nesting scrollable in the same direction layouts like ScrollableContainer and LazyColumnFor is not allowed. If you want to add a header before the list of items please take a look on LazyColumn component which has a DSL api which allows to first add a header via item() function and then the list of items via items().

I learned that I was using 
LazyColumn
 inside a 
Column
 and rectified my mistake but this error seems to continue showing regardless of any change.

I had your same error like 2 days ago when I was trying to build a like... a list within a list? i thought compose would just be able to handle it, but it wasn't. The error message kind of points you in the right direction here even though it took a while for the message to make sense to me. Basically if you need a list within a list, or just a bunch of different things in a single list, you can do
Copy code
LazyColumn{
item{ HeaderComposeable() }
items(myitems){
MyListItemComposable(it)
}

item{ AnotherHeader() }
items(anotherList){
AnotherComposable(it)
}
}
idk if that helps at all, but this doc helped me understand the idea behind the dsl https://developer.android.com/reference/kotlin/androidx/compose/foundation/lazy/package-summary#top-level-functions
Also the source has these ListDemos which were also helpful

Agreed. But it seems like it's complaining about parent 
LinearLayout
itself in which this Composable is getting rendered
It turns out Simple LinearLayout is not considered as a scrollable container but Linear Layout with weighted children is a scrollable container and thus it prevents us from using LazyColumn in such scenarios
