Dart vs Kotlin: threading

threading.dart

import 'dart:isolate';

void compute(int num) {
  final isolateName = Isolate.current.debugName;
  print('Isolate $isolateName computing $num...');
}

main() async {
  print('Spawning...');
  final isoFut1 = Isolate.spawn(compute, 1, debugName: "I1");
  final isoFut2 = Isolate.spawn(compute, 2, debugName: "I2");
  print('Waiting...');
  await isoFut1;
  await isoFut2;
  print('Done!');
}

threading.kt

import kotlinx.coroutines.*

suspend fun compute(
    num: Int
) = withContext(Dispatchers.Default) {
    val threadName = Thread.currentThread().name
    println("Thread $threadName computing $num...")
}

fun main() = runBlocking {
    println("Launching...")
    val co1Job = launch { compute(1) }
	val co2Job = launch { compute(2) }
    println("Waiting...")
    co1Job.join()
    co2Job.join()
	println("Done!")
}
