I have a SnapshotStateMap state variable and a regular Map that is generated from the state map, then provided to a Composable as follows:

val stateMap: SnapShotStateMap<...> = remember { mutableStateMapOf() }
val anotherMap: Map<...> = stateMap.map { ... }

...

DisplayMapComposable(
    map = anotherMap, 
    changeStateMap = { // Change stateMap in some way }
)

When changeMap is called inside the DisplayMapComposable and modifies stateMap , will it trigger a recomposition of the DisplayMapComposable itself?

[Zach Klippenstein (he/him) [MOD]]

Wherever you call .map on the state map that is a read, so that is what will get recomposed.

[Justin Xu]

So anotherMap will get recomposed, but that won't trigger a recomposition on DisplayMapComposable?

[Stylianos Gakis]

Since that composable takes in anotherMap and it changes, then yeah it should recompose, why wouldn't it?
