java.lang.IllegalStateException: Maximum limit of concurrent alarms 500

[zzzhhhhh001]

I used flutter_local_notifications to send notifications, and I used the loop to add 880 notifications at a time with the following error.

E/flutter (29456): [ERROR:flutter/lib/ui/ui_dart_state.cc(209)] Unhandled Exception: PlatformException(error, Maximum limit of concurrent alarms 500 reached for uid: u0a201, callingPackage: com.kk.flutter_kk, null, java.lang.IllegalStateException: Maximum limit of concurrent alarms 500 reached for uid: u0a201, callingPackage: com.kk.flutter_kk

[MaikuB]

This looks like it's to do with what was documented at https://github.com/MaikuB/flutter_local_notifications/tree/master/flutter_local_notifications#scheduled-android-notifications and there's isn't anything else the plugin can do as it's a limitation of the OS. You may need to consider if there's a different solution to your problem e.g. if using a calendar plugin is more appropriate.

Note whilst zoneScheduled() would also have this problem, should point out that schedule() is deprecated and won't be maintained
