timer_builder library

Classes

TimerBuilder: A widget that rebuilds on specific and / or periodic Timer events.

alignDateTime(DateTime dt, Duration alignment, [bool roundUp = false]) → DateTime: Rounds down or up a DateTime object using a Duration object. If roundUp is true, the result is rounded up, otherwise it's rounded down. If the duration is a multiple of days, the result will be aligned at the day mark in the timezone of the source datetime.
createTimerStream(TimerGenerator generator, Future stopSignal) → Stream<DateTime>: Creates a stream tha produces DateTime objects at the times specified by the generator. Stops the stream when stopSignal is received.
fromIterable(Iterable<DateTime> iterable) → TimerGenerator
getAlignmentUnit(Duration interval) → Duration: Returns an alignment unit can be passed to alignDateTime in order to align the date/time units. For example, if the specified interval is 15 minutes, the alignment unit is 1 minute.
periodicTimer(Duration interval, {Duration alignment = Duration.zero}) → TimerGenerator
scheduledTimer(Iterable<DateTime> schedule) → TimerGenerator

TimerGenerator = DateTime? Function(DateTime now): Used by TimerBuilder to determine the next DateTime to trigger a rebuild on
