# compose

How can I prevent LaunchedEffect running for the first time properly? The current solution is to add a "lock", but it is boilerplate.

Is it boilerplate or is it logic? It sounds like logic that you want to extract to a helper function.

I have tried to extract LaunchedEffect but it won't re-run unless I change the type of the param keys to ()->Any

Are you reacting only to changes of a state object and not to the original value it is assigned? Could you try something like

var myState by remember { mutableStateOf(1) }
LaunchedEffect(Unit) {
  snapshotFlow { myState }
    .drop(1)
    .collect { state ->
      //do something on each state change
    }
}

This should just drop the first state and run anything inside collect on every other change. Could it be something you can use?

Thank you @Stylianos Gakis , that's it.
