Remove notification after a certain time in React Native (@react-native-firebase/messaging)

Question

I have push notifications working in React Native using @react-native-firebase/messaging. I am using FCM on the backend, and it is currently showing the OS lock screen notifications on iOS and Android.

I want to clear a given notification after a certain time, or after an amount of time has passed. Is there a way to do this? Right now when I send a notification it will stick around for days if I don't click on it. I would like to take a notification down after say an hour, or at 4pm, or whatever. Front-end and/or back-end solutions welcome.

I had assumed that the "ttl" (time to live) parameter did this, but this is not the case.

Answer 1

you could use a background handler like react-native-background-fetch

In your onMessage or backgroundMessage schedule a backgroundTask for your desired time with scheduleTask().

You could use react-native-push-notification to display the notification, which has an method cancelLocalNotifications() to cancel notifications In the task you could clear the notification depending on the id

PushNotification.configure({
  onNotification: (notification) => {
    var {id} = remoteMessage.data
    
    BackgroundFetch.configure({
      minimumFetchInterval: 15
    }, async (taskId) => {
    
      PushNotification().cancelLocalNotifications(id)
      BackgroundFetch.finish(taskId);
    })
    
    BackgroundFetch.scheduleTask({
      taskId: id,
      forceAlarmManager: true,
      delay: 5000 
    });

  }
})
