Async Queue - ensure list of async task perform in order

This dart package ensure your pack of async task perform in order, one after the other.

Features

• (Normal Queue) Add multiple jobs into queue before firing
• (Auto Queue) Firing job as soon as any job is added to the queue
• (Both) Option to add queue listener that happens before or after execute every job

Installing and import the library:

Like any other package, add the library to your pubspec.yaml dependencies:

dependencies:
    async_queue: <latest_version>

Then import it wherever you want to use it:

import 'package:async_queue/async_queue.dart';

Usage

1. Normal Queue

 final asyncQ = AsyncQueue();
  asyncQ.addJob(() =>
      Future.delayed(const Duration(seconds: 1), () => print("normalQ: 1")));
  asyncQ.addJob(() =>
      Future.delayed(const Duration(seconds: 4), () => print("normalQ: 2")));
  asyncQ.addJob(() =>
      Future.delayed(const Duration(seconds: 2), () => print("normalQ: 3")));
  asyncQ.addJob(() =>
      Future.delayed(const Duration(seconds: 1), () => print("normalQ: 4")));

  await asyncQ.start();

    // normalQ: 1
    // normalQ: 2
    // normalQ: 3
    // normalQ: 4

2. Auto Star Queue

final autoAsyncQ = AsyncQueue.autoStart();

  autoAsyncQ.addJob(() =>
      Future.delayed(const Duration(seconds: 1), () => print("AutoQ: 1")));
  await Future.delayed(const Duration(seconds: 6));
  autoAsyncQ.addJob(() =>
      Future.delayed(const Duration(seconds: 0), () => print("AutoQ: 1.2")));
  autoAsyncQ.addJob(() =>
      Future.delayed(const Duration(seconds: 0), () => print("AutoQ: 1.3")));
  autoAsyncQ.addJob(() =>
      Future.delayed(const Duration(seconds: 4), () => print("AutoQ: 2")));
  autoAsyncQ.addJob(() =>
      Future.delayed(const Duration(seconds: 3), () => print("AutoQ: 2.2")));
  autoAsyncQ.addJob(() =>
      Future.delayed(const Duration(seconds: 2), () => print("AutoQ: 3")));
  autoAsyncQ.addJob(() =>
      Future.delayed(const Duration(seconds: 1), () => print("AutoQ: 4")));

    // AutoQ: 1
    // AutoQ: 1.2
    // AutoQ: 1.3
    // AutoQ: 2
    // AutoQ: 2.2
    // AutoQ: 3
    // AutoQ: 4

Add Queue Listener

  final asyncQ = AsyncQueue();

  asyncQ.addQueueBeforeListener((event) => print("before $event"));
  asyncQ.addQueueAfterListener((event) => print("after $event"));
