I have `LazyColumn` that I pass list of items into. I want to update items, new list with appended items, every second of so. when new items are received `LazyColumn` flickers and resets scroll to top.
this happens even when I’m using `ImmutableList` and having item `key` defined.
how can I append items without flicker and moving to top?

Does your code remember scroll state of LazyColumn?

yes it does. but even if that works there is flicker issue also

you need to override the `hashCode()`  and `equals()` of the items that are getting diff'ed, which is what's causing the flicker I think, it's not just the keys.

```If these items are complex objects, properly implemented hashCode() and equals() methods help Compose efficiently identify changes```
you need to help it identify content or instantiation differences `(one is a structural / partial difference, the other is difference in entire object itself )`

this used to be a part of the `DiffUtil` process too

either that or your keys are not unique or not properly tied to the item's identity (key) (you need to make sure each item has a unique key and they're not all the same )

<@U01QLPSBKLY> it’s pretty basic code. flow that emits new list with appended elements every second and the most basic `LazyColumn` you can imagine :smile:

btw. nothing worked. keys are unique, overriding hash and equals didn’t do anything :man-shrugging:

Can you make a small reproduction? It shouldn't flicker, so there's something specific about your code.
