Does ScrollableColumn not support nested scrolling?
I have a LazyRowFor and a LazyColumnFor inside a ScrollableColumn and it messed up vertical scrolling. Fling scroll doesn't work.

ScrollableColumn {
    Text(...)
    LazyRowFor(...)
    LazyColumnFor(...)
}

Why not use directly:

LazyColumn {
    Text(...)
    LazyRowFor(...)
    // Additional content
}

?

(I tried using LazyColumn stand-alone, without nested scrolling, and with very simple items, fling wasn't working and it was super laggy)

It's not stable so I'm using LazyColumnFor rn. But I'll try with LazyColumn . Is there a sample for LazyColumn ? Looks like it doesn't take a composable argument

[Yann Badoual]

It does, LazyColumnFor and LazyColumn use the same composable under the hood LazyFor .
I'm not sure what are the differences between the two, except that one is wrapping a list of items (LazyColumnFor) while the other has a more similar api with Column

[Se7eN]

It doesn't... Maybe they changed it in alpha03?

[Yann Badoual]

content is what you're looking for

[Se7eN]

Here's the error because content isn't composable

[Yann Badoual]

They changed it, now you have to wrap items inside an item call

[Se7eN]

LazyColumnFor's content is composable

[Yann Badoual]

`

LazyColumn {
   item {
      // I'm a composable
   }
}

[Se7eN]

Got it

[Yann Badoual]

There's also items and itemsIndexed

[Se7eN]

Thanks!

[Yann Badoual]

Tell me if it's better, I'm curious

[Se7eN]

Lags and fling doesn't work just like ScrollableColumn

[Andrey Kulikov]

could you please share the final code you have? yes, it is tricky to have two components scrollable in the same direction nested, but if you use LazyColumn dsl instead the fling should work fine

[Se7eN]

LazyColumn {
   item {
      Button(...)
      LazyRowFor(...)
      LazyColumnFor(...)
   }
}

I can make a sample project if you want

[Yann Badoual]

you shouldn't need the LazyColumnFor anymore (I think)

[Se7eN]

So...a loop?

[Andrey Kulikov]

LazyColumn {
   item {
      Button(...)
   }
   item {
      LazyRowFor(...)
   }
   items(yourList) {
       ... item of the list
   }
}

[Andrey Kulikov]

could you please try something like this?

[Se7eN]

Sure wait

[Se7eN]

Yeah the fling works great now

[Se7eN]

Although it's kinda lagging a little more than LazyColumnFor but that's expected right now I guess?

[dambakk]

I had a ScrollableColumn with a LazyColumnFor inside and fling didn’t work. Replacing the lazy column with a forEach did the trick, fling now works perfectly 👌
