В своем приложении я использую плагин flutter_local_notifications: ^1.4.2 для локальных уведомлений. Пользователь выбирает, в какие дни недели запланировать alarm, и при сохранении я передаю объект alarm методу setSchedulerNotifications, чтобы установить уведомление для каждого дня в списке repeatWeekdays будильника. I l oop через список repeatWeekdays и установить уведомление для каждого l oop, с идентификатором, который передается в идентификаторе тревоги + номер l oop, чтобы быть инкрементным. Пока все работает, как ожидалось.
Теперь, когда тревога редактируется (другое время), при сохранении я передаю новую тревогу методу modifySchedulerNotification, который сначала вызывает метод deleteSchedulerNotifications (который имеет тот же l oop для вычисления идентификатора уведомления), а затем снова вызывает setSchedulerNotifications.
Распечатки показывают, что идентификаторы уведомлений в setSchedulerNotifications верны, и они согласованы в deleteSchedulerNotifications и втором вызове setSchedulerNotifications, но когда они установлены во второй раз (те же идентификаторы, что и в первый раз) уведомления не срабатывают в новое время, а срабатывают в старое время.
Можете ли вы заметить, что я делаю не так?
