dart中如何实现优先队列？

Question

Is Priority Queue collection available in dart because I am not able to use priority queue in flutter?

If so, then please write a snippet of how to use it. I am not able to find any handy explanation of how to use Priority Queue in flutter.

Answer 1

import 'package:collection/collection.dart';

void main() {
  // queue that prioritizes longer strings
  final queue = PriorityQueue<String>((a, b) => b.length.compareTo(a.length));
  queue..add('foo')..add('bazars')..add('zort');
  
  while (queue.isNotEmpty) {
    print('* ${queue.removeFirst()}');
  }
}
