Script – Contacts Flow

suspend fun NavFlowScriptScope<ContactsOutput, *>.runContactsFlow(
    repository: ContactsRepository,
    nodeScope: CoroutineScope
) {
    while (true) {
        showContactsList(repository)
        when (val action = awaitOutputCase<ListAction> {
            on<ContactsOutput.OpenContact> { ListAction.Open(it.id) }
            on<ContactsOutput.CreateContact> { ListAction.Create }
        }) {
            is ListAction.Open -> runDetailsFlow(action.id, repository, nodeScope)
            ListAction.Create -> runEditorFlow(null, repository, nodeScope)
        }
    }
}

When to use:

• Reusable list/details/editor flows where UI should stay reactive and navigation policy stays central.

Why it matters:

• The list/details/editor policy stays in one loop; Compose just renders the current node.
• Shows how to reuse the same editor sub-flow for “open contact” and “create contact.”
• Full implementation in sample-app-flowscript includes refresh + sub-flow reuse without UI branching.
