Dart .length

In Dart, the .length property returns the number of elements in a queue.

Syntax

queueName.length

• queueName: The name of the queue to be checked.

Example

The below example creates a queue named example_queue, appends five integer elements to it, and calculates its length using the .length property:

import 'dart:convert';
import 'dart:collection';

void main()
{
  // Initializing a queue
  Queue<int> example_queue = Queue<int>();

  // Appending elements to the queue
  example_queue.addAll([1, 3, 5, 2, 0]);

  // Calculating the length of the queue
  print("The length of the queue is: ${example_queue.length}");
}
