androidx.appstate.transform

fun TransformScope(): TransformScope

Creates a TransformScope.

suspend fun listener(
    dispatcher: CoroutineDispatcher = Dispatchers.Default,
    onUpdate: @Composable () -> Unit
): Unit

Suspend function that executes a Composable onUpdate block in a headless Composition.

This function bridges reactive Compose state (or Flows collected as state) into a continuously updated State object outside of a traditional Compose UI hierarchy. The onUpdate block is automatically recomposed whenever any Compose state it reads is updated.

fun <R : Any?> transform(
    initialValue: R,
    scope: CoroutineScope,
    dispatcher: CoroutineDispatcher = Dispatchers.Default,
    onUpdate: @Composable (R) -> R
): State<R>

This is a convenience function for TransformScope.launchTransform that runs the transform within the given CoroutineScope.

This function bridges reactive Compose state (or Flows collected as state) into a continuously updated State object outside a traditional Compose UI hierarchy. The transform block is automatically recomposed whenever any Compose state it reads is updated, and the newly returned value is pushed into the resulting State.
