Dart vs Kotlin: async sequential

async_sequential.dart

Future<String> requestToken() async {
  await Future.delayed(Duration(seconds: 1));
  return "TOKEN";
}

Future<void> postUserName(String token, String name) async {
  await Future.delayed(Duration(seconds: 1));
}

void main() async {
  String token = await requestToken();
  await postUserName(token, "David");
  print("Done!");
}

async_sequential.kt

import kotlinx.coroutines.*

    delay(1000)
    return "TOKEN"

suspend fun postUserName(token: String, name: String) {
    delay(1000)
}

fun main() = runBlocking {
    var token: String = requestToken()

    println("Done!")
