What does this PR do?
Improves null handling in the
ResetApplicationIconBadgeNumber()method by adding an early return in the callback whennotificationArrayis null. This prevents anArgumentNullExceptionwhen iOS'sGetDeliveredNotifications()callback returns a null array instead of an empty array.Why are we doing this? Any context or related work?
The synchronous version of
ResetApplicationIconBadgeNumber()was throwingArgumentNullExceptionbecause the iOS SDK'sGetDeliveredNotifications()callback can pass a null notification array, but the code unconditionally calledAddRange(notificationArray)without null checking. The async version (ResetApplicationIconBadgeNumberAsync()) doesn't have this issue becauseGetDeliveredNotificationsAsync()returns an empty array instead of null.Changes made:
AddRange()inPlatforms/iOS/LocalNotificationCenter.csAddRange()inPlatforms/MacCatalyst/LocalNotificationCenter.csThis approach treats a null notification array gracefully and continues execution as if there are no notifications, which is the correct behavior.
Fixes: #545
