Idiom #45 Pause execution for 5 seconds

Sleep for 5 seconds in current thread, before proceeding with the next instructions.

The pedestrian walks, then stays still for 5 seconds, then resumes walking 
import 'dart:io';
sleep(const Duration(seconds: 5));

sleep is only available if dart:io is available (ie. on server side)

Attention! sleep stops all asynchronous execution within the whole Isolate, e.g. will stop all updates for the complete Flutter GUI for that time.
import "dart:async";
await new Future.delayed(const Duration(seconds : 5));

Waiting makes sense in asynchronous code. It's not done that often, and there is no simple primitive for it.

This will not pause the *thread*, but will delay the rest of the current async function.
System.Threading.Tasks;
Task.Delay(5000);
using System.Threading;
Thread.Sleep(5000);

Takes an int value representing milliseconds.
delay 5.0;
