Dart by Example: Queue

import 'dart:collection';
main() {
  // Queues are optimized for adding to the head or tail
  // Items cannot be accessed by their index.
  var q = new Queue.from([300, 200, 100, 500]);
  // Queues implement Iterable:
  print(q.takeWhile((i) => i > 100));
  // Consuming a queue
  while(q.first > 100) {
    q.removeFirst();
  }
  print(q);
}
 

$ dart queue.dart
(300, 200)
{100, 500}
