Hello, has anyone else experienced this nested scrolling error when trying to persist scroll state?

java.lang.IllegalStateException: Nesting scrollable in the same direction layouts like ScrollableContainer and LazyColumn is not allowed.

I have a LazyColumn in a Fragment with a LinearLayout

This all works fine until I attempt to add .verticalScroll(rememberScrollState()) to the LazyColumn and I get the above error

[Andrey Kulikov]

why do you want to add verticalScroll on LazyColumn? LazyColumn is scrollable already

[Jordan Carlyon]

Maybe I misread the documentation but that is what was being done in the sample

State of the scroll. Allows the developer to change the scroll position or get current state by calling methods on this object. To be hosted and passed to Modifier.verticalScroll or Modifier.horizontalScroll

[Jordan Carlyon]

I see now that they are doing this on a Column and not a LazyColumn which may be an issue

[mcpiroman]

On Lazy collections you have to do it by passing scroll state as `state`parameter to the constructor, not via Modifier. But I'm interested how to add horizontal scrolling to the LazyColumn, which also produces the same error.

Actually it is not ScrollState it is LazyListState which is something else entirely 😢

[Jordan Carlyon]

Is it a bug with Compose that scrollable() is accessible in LazyLists then?

[Jordan Carlyon]

At a minimum it's definitely odd that it's a run time exception rather than compile time.
