Hello! Even though I use a very unique identifier, I am sometimes getting below and app is crashing.

If you are using LazyColumn/Row please make sure you provide a unique key for each item.

Did anybody face a similar problem with

LazyList

?

We can't say much without seeing you code

Thanks. I basically get a list of instruments from VM and subscribe them as state

val instruments by viewModel.output.instruments.subscribeAsState(initial = emptyList())

and passing this list to LazyList as follow

LazyColumn(
    state = rememberLazyListState(),
    modifier = Modifier.fillMaxSize()
) {
    ...
    items(
        items = instruments,
        key = { it.isin },
        contentType = {
            when {
                it.derivativeTags?.optionTypeText != null -> CONTENT_TYPE_DERIVATIVES
                it.hasSavingsPlan -> CONTENT_TYPE_SAVINGS_PLAN
                sorting.criteria == Criteria.PositionSize -> CONTENT_TYPE_POSITION_SIZE
                else -> CONTENT_TYPE_METRIC
            }
        }
    ) { item ->
        ...
    }
}

There are two possibilities: 1. You are passing another

item

which (mistakenly) has the same key of a `instrument`; 2.

isin

is not unique. Is it complex object?

I only perform sorting on the list as we have a sorter in the UI

val instruments by viewModel.output.instruments.subscribeAsState(initial = emptyList())

this line might be suspicious? 🤔

isin

is an alphanumeric text like

US14583249X

Add some code to verify that all the

isin

are unique (just for debugging purposes)

instruments.forEach { instrument ->
  require(instruments.none { it.isin == instrument.isin })
}

Can you confirm all the

isin

are unique?

Yes they are unique
