Constructors

NotificationAndroidCrontab({DateTime? initialDateTime, DateTime? expirationDateTime, List<DateTime>? preciseSchedules, String? crontabExpression, String? timeZone, bool allowWhileIdle = false, bool repeats = false, bool preciseAlarm = true})
Constructs a NotificationAndroidCrontab with various crontab-based scheduling options.
NotificationAndroidCrontab.daily({required DateTime referenceDateTime, bool allowWhileIdle = false})
Initializes a notification crontab schedule to be triggered daily at a specific time. referenceDateTime: The time at which the notification should be scheduled each day. allowWhileIdle: Allows the notification to display even when the device is in low battery mode.
NotificationAndroidCrontab.fromDate({required DateTime date, int initialSecond = 0, bool allowWhileIdle = false})
Initializes a notification schedule based on a single date reference.
NotificationAndroidCrontab.hourly({required DateTime referenceDateTime, bool allowWhileIdle = false})
Initializes a notification crontab schedule to be triggered hourly at a specific minute and second. referenceDateTime: The minute and second at which the notification should be scheduled each hour. allowWhileIdle: Allows the notification to display even when the device is in low battery mode.
NotificationAndroidCrontab.minutely({required DateTime referenceDateTime, bool allowWhileIdle = false})
Initializes a notification crontab schedule to be triggered every minute at a specific second. referenceDateTime: The second at which the notification should be scheduled each minute. allowWhileIdle: Allows the notification to display even when the device is in low battery mode.
NotificationAndroidCrontab.monthly({required DateTime referenceDateTime, bool allowWhileIdle = false})
Initializes a notification crontab schedule to be triggered monthly at a specific date and time. referenceDateTime: The date and time at which the notification should be scheduled each month. allowWhileIdle: Allows the notification to display even when the device is in low battery mode.
NotificationAndroidCrontab.weekendDay({required DateTime referenceDateTime, bool allowWhileIdle = false})
Initializes a notification crontab schedule to be triggered on weekend days (Saturday and Sunday) at a specific time. referenceDateTime: The time at which the notification should be scheduled on weekend days. allowWhileIdle: Allows the notification to display even when the device is in low battery mode.
NotificationAndroidCrontab.weekly({required DateTime referenceDateTime, bool allowWhileIdle = false})
Initializes a notification crontab schedule to be triggered weekly at a specific date and time. referenceDateTime: The date and time at which the notification should be scheduled each week. allowWhileIdle: Allows the notification to display even when the device is in low battery mode.
NotificationAndroidCrontab.workweekDay({required DateTime referenceDateTime, bool allowWhileIdle = false})
Initializes a notification crontab schedule to be triggered on workweek days (Monday to Friday) at a specific time. referenceDateTime: The time at which the notification should be scheduled on workweek days. allowWhileIdle: Allows the notification to display even when the device is in low battery mode.
NotificationAndroidCrontab.yearly({required DateTime referenceDateTime, bool allowWhileIdle = false})
Initializes a notification crontab schedule to be triggered yearly at a specific date and time. referenceDateTime: The date and time at which the notification should be scheduled each year. allowWhileIdle: Allows the notification to display even when the device is in low battery mode.

Properties

allowWhileIdle ↔ bool
Allows the notification to be displayed even when the device is in low battery mode.
getter/setter pairinherited
crontabExpression → String?
Gets the crontab expression as a repetition rule with seconds precision (if set to *, considers all possible values for the respective component as valid). For more information, please take a look at https://www.baeldung.com/cron-expressions
no setter
delayTolerance ↔ int
Delay tolerance in milliseconds for scheduling the notification. Minimum tolerance is typically 600,000 ms (10 minutes).
getter/setter pairinherited
expirationDateTime → DateTime?
Gets the final limit date that a schedule is considered valid.
no setter
hashCode → int
The hash code for this object.
no setterinherited
initialDateTime → DateTime?
Gets the initial limit date that a schedule is considered valid.
no setter
preciseAlarm ↔ bool
Requires precise timing for the notification schedule, especially important on devices with strict power-saving features.
getter/setter pairinherited
preciseSchedules → List<DateTime>?
Gets a list of precise valid schedule dates.
no setter
repeats ↔ bool
Indicates whether the notification should be delivered once (false) or rescheduled each time it's delivered (true).
