How to Schedule Background Tasks In Flutter?

We would recommend you to the medium article for the same. However, we thought it was way too complicated to set up so it just happens we created a plugin that aids you with this…

//Provide a top level function or static function.
//This function will be called by Android and will return the value you provided when you registered the task.
//See below
void callbackDispatcher() {
  Workmanager.executeTask((task) {
    print("Native echoed: $task");
    return Future.value(true);

    callbackDispatcher, //the top level function.
    isInDebugMode: true //If enabled it will post a notification whenever the job is running. Handy for debugging jobs

For now, it only works for android projects. We have iOS support now too. It is still early alpha but gives ago.

SOLUTION: Cron is another best solution to schedule background tasks. Cron runs tasks periodically at fixed times, dates, or intervals. But the only disadvantage of corn is once the app kills, the cron not working in the background as expected.

A simple usage example

import 'package:cron/cron.dart';

main() {
  var cron = new Cron();
  cron.schedule(new Schedule.parse('*/3 * * * *'), () async {
    print('every three minutes');
  cron.schedule(new Schedule.parse('8-11 * * * *'), () async {
    print('between every 8 and 11 minutes');
