android.app.RemoteServiceException$ForegroundServiceDidNotStopInTimeException

[asiteandroid]

On Android 15, foreground services of type dataSync must stop within a shorter timeout. We are observing a crash on devices running Android 15 with the following exception, even when using the latest flutter_local_notifications version (19.4.0).

Reference: Android 15 behavior changes for foreground services: https://developer.android.com/about/versions/15/behavior-changes-15#datasync-timeout

Crash Log:

flutter_local_notifications versions tested:

✅ 19.3.0 (crash observed)

✅ 19.4.0 (crash still occurs)

Expected Behavior: The foreground service should either complete or stop within the timeout window as per Android 15’s behavior change, or at least handle it gracefully without crashing.
