Thanks for watching the video. Yes you set duration in days using days property of Duration class. Refer below link for more details, api.flutter.dev/flutter/dart-core/Duration/inDays.html
how to customize this. by default in the notification it is showing like result dart etc and some emogi's can i remove that is it possible. can you suggest another good package for putting reminder for events
how can I run the task after rebooting the device? for example, to set notifications again, since they are reset after a reboot, they say this can be done using this workmanager package

Thanks for watching the video. Sorry the minimum duration you can set using workmanager is 15 mins. Android doesn't allow duration less than 15 mins for workmanager. May be you will need to check other approach for this requirement.
Hi sir nice tutorial, I wanna ask something, I want to make background local notifications using work manager and provider state management, but I cannot access the context for provider because it is outside of the widget, how can I get the context?thanks in advance

@@EffortlessCodeLearningThanks for reply, Main.dart have this code void callbackDispatcher() { Workmanager().executeTask((taskName, inputData) async { //show the notification await Firebase.initializeApp(); totalcalls() async { var callsRecord = queryCallsRecord( queryBuilder: (callsRecord) => callsRecord .where('attended', isEqualTo: 'false')); var _equals = await callsRecord.length; return createcallNotification(title: "Calls Pending", count:callsRecord.length );}

@Piyush, what is the exact issue you are facing with this code? Did you try to print any sample message in Workmanager().executeTask method to check if it is getting triggered?
Yes. it will work if app is closed or lost the focus. To work after reboot, need some other workaround. Refer below link, there are ways provided by other developers, github.com/googlecodelabs/android-workmanager/issues/157 github.com/fluttercommunity/flutter_workmanager/issues/180
When I close the Android app on my emulator, I got the message "Lost connection to device." in the terminal which means the app will not be running in the background anymore. Any thoughts on this?
This message is because the socket connection between your editor(Android studio/ VS code) & app on emulator is terminated. App should be working in the background. Best way to verify it on really device. You can deploy your app on mobile & check.
@@EffortlessCodeLearning Thank you for the reply. I have also tried running this app on my android device and it also fully closes the app. I get the same message "Lost connection to device" when closing the app. I ended up using the package flutter_background_service which works great so far.

Hi Thanks for the video I have question here you initialize workmanager in main() The print statement taskname why not continually print logcat ..? background continually print what can I do Periodic task we can run 15min once only we get the output..but I need 5 seconds once if it's possible ..? Or send me message to my mail id
@Paranthaman Arumugam: Thanks for watching the video. Workmanager support minimum task schedule time is 15 min. Even though if you set less than 15 min, it sets it back to 15 min. If you want scheduling time less 15 min then you need to use any alternate approach like, You can use Timer.periodic(Duration(seconds: 5), {}) method, but the timer work only when app is running, it will be stopped as soon as app is closed. So you will have to write the background service/code explicitly in android/iOS.
@@EffortlessCodeLearning @Effortless Code Learning Thanks for your reply that's you come up with correct point. And I done Timer.periodic that's fine working me Thanks once again.

is it possible to throw a APi call post or get when app in terminate state using this method?
The periodic task doesn’t work on iOS. Do you know an alternative for that?
