rememberUpdatedState
@Composable
public fun <T> rememberUpdatedState(newValue: T): State<T>remember a mutableStateOf newValue and update its value to newValue on each recomposition of the rememberUpdatedState call.
rememberUpdatedState should be used when parameters or values computed during composition are referenced by a long-lived lambda or object expression. Recomposition will update the resulting State without recreating the long-lived lambda or object, allowing that object to persist without cancelling and resubscribing, or relaunching a long-lived operation that may be expensive or prohibitive to recreate and restart. This may be common when working with DisposableEffect or LaunchedEffect, for example:
LaunchedEffects often describe state machines that should not be reset and restarted if a parameter or event callback changes, but they should have the current value available when needed. For example:
By using rememberUpdatedState a composable function can update these operations in progress.
