How to create a scheduled service in Flutter

Question

How can you create a scheduled service in Flutter, which will be triggered at a specific time every day, and it will run some code? It needs to work for both Android and IOS and even if the app is terminated.

Solution

You could make use of the alarm manager package.

A simple implementation of the same would look like below.

import 'dart:async';

import 'package:android_alarm_manager/android_alarm_manager.dart';
import 'package:flutter/widgets.dart';

void doStuff() {
  print("do stuff every minute");
}

Future<void> main() async {
  final int periodicID = 0;

  // Start the AlarmManager service.
  await AndroidAlarmManager.initialize();

  runApp(const Center(
      child:
      Text('See device log for output', textDirection: TextDirection.ltr)));
  await AndroidAlarmManager.periodic(
      const Duration(minutes: 1), periodicID, doStuff,
      wakeup: true);
}

Will this work for IOS as well? And when the app is terminated either by user or OS?
