Hey guys,

Is there a way to improve this code:

val items = remember {
    initialize items calulcation
}
SideEffect {
    update items calculation
}

to make it run only initalize items caluclation when composing for the first time?

That code already runs initialize... when composing for the first time only. Subsequent compositions will just return the remembered items (until the composable is removed from composition, in which case its remembered state is also removed from from composition/memory)

[Radoslaw Juszczyk]

Yes, what I want is it to not run update items calculation when composing for the first time

[efemoney]

Put it behind a boolean? currentComposer.inserting or something, although <-- that is not recommended. You can also maintain state in composition that is updated from the side effect

[efemoney]

val abc by remember { mSO(false) }

SideEffect { 
  if (!abc) abc = true else update items
}
