Flutter local notifications - flutter

Question

I' m using Flutter local notification for my app with repeatInterval, it's working fine but i want notifications to be different from one to another, cause with this code i get the same string from list over and over again. How can i edit the code to get another string when user get a notification?
Future<void> showNotification(int id, String title, String body) async {
await flutterLocalNotificationsPlugin.periodicallyShow(
id,
title,
body,
RepeatInterval
.everyMinute,
const NotificationDetails(
// Android details
android: AndroidNotificationDetails('main_channel', 'Main Channel',
channelDescription: "ashwin",
importance: Importance.max,
priority: Priority.max),
// iOS details
iOS: DarwinNotificationDetails(
sound: 'default.wav',
presentAlert: true,
presentBadge: true,
presentSound: true,
),
),
androidAllowWhileIdle:
true, // To show notification even when the app is closed
);
}
Here is the code from another class NotificationService and i called it here:
onPressed: () {
setState(() {
showToast();
NotificationService().showNotification(
1,
'$randomNames${widget.userPost}',
randomName!,
);
});
},
The problem it s only updating when i press the button again, i want to be updated every time when the user get a notification. Anybody know how to do that?
String? randomName;
final random = new Random();
randomName = names[random.nextInt(names.length)];
This is where i randomized the list called names, this code and the one from above are from a diferent screen class called IntroPage
How can I solve this problem?

Answer 1

if you want to set different notif, which means you need the the system to execute the function. but since its repeated notif, and the message was static, consider to use Workmanger.
https://pub.dev/packages/workmanager
with this ,you can execute your function to generate random text as a notification.
#pragma('vm:entry-point')
void callbackDispatcher() {
Workmanager().executeTask((task, inputData) {
//you function here to generete random String
// then show local notificaton
showNotification(); // call local notificaiton
return Future.value(true);
});
}
void main() {
Workmanager().initialize(
callbackDispatcher, // The top level function, aka callbackDispatcher
isInDebugMode: true // If enabled it will post a notification whenever the task is running. Handy for debugging tasks
);
Workmanager().registerPeriodicTask("task-identifier", "simpleTask");
runApp(MyApp());
}
