Would need more info on what your app is doing, which version of the plugin you're using etc. The code is open-source so you can check what your app is doing to see how it relates to the crash given you have a stack trace

MaikuB · 2019-12-27T23:25:53Z

Also note that you can have your app point to a local copy of the plugin or via a Git reference. This could be used to track the problem and submit a PR back should you find out what the issue is

JCKodel · 2019-12-27T23:35:48Z

The problem is that this don't happen in any of my devices (of course, "works on my machine" ®)
I would love to help, but I don't have any idea of what can trigger this behavior.

Anyway, flutter_local_notifications: ^0.9.1

MaikuB · 2019-12-27T23:49:02Z

Would the users that have those crashes have a version of your app that is using version 0.9.1 of the plugin? Line 584 of the FlutterLocalNotificationsPlugin.java file currently doesn't point to code that would deal with an integer so I suspect it's on an older version of the plugin. Regardless, without more information, this may not be something I'll be able to track down to fix. Be good if you can provide more info about what kind of code you have has well when it comes to notifications. Snippets would help.

yeskayviswa · 2020-08-24T16:57:56Z

This is a Crashlytics report, can't pinpoint exactly what's going on.

I'm using flutter_local_notifications: ^1.4.4+4

  }```

yourshinsuke · 2020-08-31T05:31:28Z

Did you fix?

yeskayviswa · 2020-08-31T05:54:55Z

Yes. The integer value I've provided in dart, exceeded the limit of maximum integer value in java file. So i reduced the number within the limit of integer max value and then the issue was resolved.

Try to reduce the id value.

yourshinsuke · 2020-08-31T06:02:12Z

I just add the code in initStatus, and error didn't show. but I don't know what it is.

    var initializationSettingsAndroid =
        AndroidInitializationSettings('@mipmap/ic_launcher');
    var initializationSettingsIOS = IOSInitializationSettings();
    var initializationSettings = InitializationSettings(
        initializationSettingsAndroid, initializationSettingsIOS);
    flutterLocalNotificationsPlugin.initialize(
      initializationSettings,
    );

yourshinsuke · 2020-08-31T06:06:37Z

@yeskayviswa Thank you for replying.

Try to reduce the id value.

I pushed channel_id, ZONE_ALERT via Cloud Messaging in Firebase.
what is id ? it should be number?

yeskayviswa · 2020-08-31T06:32:30Z

The error I faced is in flutterLocalNotificationsPlugin.schedule( ) function. My inttaskid was more than the limit.

That's the id I've mentioned

mercatelli · 2020-09-08T21:44:34Z

Yes. The integer value I've provided in dart, exceeded the limit of maximum integer value in java file. So i reduced the number within the limit of integer max value and then the issue was resolved.

Try to reduce the id value.

Hi @yeskayviswa Sorry I'm a little noob. I'm with the same problem and using five tipes of notification (every minute, hourly, every day, every week and specific Time) I put the IDs 01, 02, 03, 04 and 05. Qhat I can do to solve this?

dikshantrawal · 2022-02-16T11:04:04Z

where you have exceed the limit, can you explain this

dikshantrawal · 2022-02-16T11:08:39Z

This is the crashlytics report when I have updated the version. And the application is crashing only in release mode.

Make sure you've done the release build configuration

Seems that this is related to ProGuard and R8. As I was making changes to upgrade to AGP8, I have added this to gradle/properties file:

android.enableR8.fullMode=true

Removing this line seems to fix the issue.

PeperMarkreel · 2024-01-14T16:10:00Z

I have the same on my local development device, with usb attached to the debugger. A simple scheduled notification works, but somehow when I want to schedule my app specific notifications, I get this crash.

@MaikuB

We are getting the same error suddenly, we did not change any code since many versions regarding scheduling local notification. Since last two version after upgrading the plugin to 16.0.0 we are getting the crash event for many users in firebase crashlytics. Any idea how to solve this error ? this is very important error as it has decreased our crash free users to almost 50%. Let me know if you have any idea on this.
