Hi, i using a model class like this

SomeClass(
var badge: MutableState<Badge?> ......
)

But when i trying to update the badge property it Recompose even if the Badge Object is same.

how are you updating badge?

[Tash]

make sure you're updating badge.value and not the badge MutableState instance. might be easier to use property delegates and write it as var badge by mutableStateOf<Badge?> instead so that you can read/write to it as a regular var.

I'm updating it like this

pack.badgeText = OPEN(context.getString(R.string.open))

Hard to debug this without seeing more code for context. Can you post the composable that’s recomposing and the code that updates that state?

I'm not sure it's the correct way to solve this issue, but I have now a map that has Badges and it now only recomposes the item which is change

val packBadges = mutableStateMapOf<String,BADGE?>()

and on the Observing side

PackItem(
    modifier = Modifier
        .width(boxWidth)
        .padding(horizontal = 8.dp),
    entry.packName,
    entry.lections.map { it.name }.joinToString { it },
    emojiText = entry.emoji,
    coins = entry.coins,
    bagText = packBadges["${entry.lang}${entry.pacId}${entry.packOwnerId}${entry.func}"]
) {
    onPackSelected(entry)
    when(packBadges["${entry.lang}${entry.pacId}${entry.packOwnerId}${entry.func}"]) {
        is OPEN ->  onOpenLections()
        is GET ->  getLections()
        is COIN ->  getLectionsWithCoins(entry.coins)
    }
}
