Overview

In Kotlin, a LaunchedEffect in the composable usually expresses the same thing.

Modifier.task(action = { })

This is the Kotlin form of SwiftUI View.task(name:priority:file:line:_:): SwiftUI documentation. In Swift it reads:

@export(implementation) nonisolated func task(name: String? = nil, priority: TaskPriority = .userInitiated, file: String = #fileID, line: Int = #line, _ action: sending @escaping @isolated(any) () async -> Void) -> some View
