DateTimeWatcher class - flutter_watcher library

Constructors

DateTimeWatcher(DateTime initial)

Properties

day → int: The day of the month [1..31].
no setteroverride
hashCode → int: The hash code for this object.
no setterinherited
hasListeners → bool: Whether any listeners are currently registered.
no setterinherited
hour → int: The hour of the day, expressed as in a 24-hour clock [0..23].
no setteroverride
isDisposed → bool: Flag which returns true if you called the dispose method. It is useful when you want to safely do some operations on the Watcher without getting an exception if it gets disposed.
no setterinherited
isUtc → bool: True if this DateTime is set to UTC time.
no setteroverride
microsecond → int: The microsecond [0...999].
no setteroverride
microsecondsSinceEpoch → int: The number of microseconds since the "Unix epoch" 1970-01-01T00:00:00Z (UTC).
no setteroverride
millisecond → int: The millisecond [0...999].
no setteroverride
millisecondsSinceEpoch → int: The number of milliseconds since the "Unix epoch" 1970-01-01T00:00:00Z (UTC).
no setteroverride
minute → int: The minute [0...59].
no setteroverride
month → int: The month [1..12].
no setteroverride
runtimeType → Type: A representation of the runtime type of the object.
no setterinherited
safeMode → bool: safeMode if enabled will not allow any setting of value or notifying any listeners if the Watcher isDisposed
finalinherited
second → int: The second [0...59].
no setteroverride
stream → Stream<DateTime>: Converts the Watcher into a Stream. This stream emits values whenever the value changes. The use of distinct ensures that consecutive duplicate values are filtered out, thus the stream only emits when the value actually changes.
no setterinherited
timeZoneName → String: The time zone name.
no setteroverride
timeZoneOffset → Duration: The time zone offset, which is the difference between local time and UTC.
no setteroverride
v ↔ DateTime: Equivalent to the getter value but in shorter syntax.
getter/setter pairinherited
value ↔ DateTime: The current value stored in this watcher.
getter/setter pairinherited
weekday → int: The day of the week monday..sunday.
no setteroverride
year → int: The year.
no setteroverride

Methods

add(Duration duration) → DateTime: Returns a new DateTime instance with duration added to this.
override
addListener(VoidCallback listener) → void: Register a closure to be called when the object changes.
inherited
compareTo(DateTime other) → int: Compares this DateTime object to other, returning zero if the values are equal.
override
debounce(Duration duration, void action(DateTime value)) → VoidCallback: Registers a debounced callback which is invoked only after the notifier's value is stable for the specified duration.
inherited
difference(DateTime other) → Duration: Returns a Duration with the difference when subtracting other from this.
override
dispose() → void: Discards any resources used by the object. After this is called, the object is not in a usable state and should be discarded (calls to addListener will throw after the object is disposed).
inherited
isAfter(DateTime other) → bool: Returns true if this occurs after other.
override
isAtSameMomentAs(DateTime other) → bool: Returns true if this occurs at the same moment as other.
override
isBefore(DateTime other) → bool: Returns true if this occurs before other.
override
isEqual(Object other) → bool: Returns true if other is a DateTime at the same moment and in the same time zone (UTC or local).
noSuchMethod(Invocation invocation) → dynamic: Invoked when a nonexistent method or property is accessed.
inherited
notifyListeners() → void: Call all the registered listeners.
inherited
onChange(void action(DateTime value)) → VoidCallback: Registers a callback to be invoked whenever the ValueNotifier's value changes.
inherited
refresh() → void: Rebuilds and trigger any listeners of any WatchValue or watch attached to that Watcher.
inherited
removeListener(VoidCallback listener) → void: Remove a previously registered closure from the list of closures that are notified when the object changes.
inherited
setWithoutNotify(DateTime newValue) → void: inherited
subtract(Duration duration) → DateTime: Returns a new DateTime instance with duration subtracted from this.
override
toIso8601String() → String: Returns an ISO-8601 full-precision extended format representation.
override
toLocal() → DateTime: Returns this DateTime value in the local time zone.
override
toString() → String: A string representation of this object.
override
toUtc() → DateTime: Returns this DateTime value in the UTC time zone.
override
updateIf(bool condition(DateTime), DateTime newValue) → void: Updates the ValueNotifier's value to newValue if condition returns true.
inherited
updateOnAction<R>(R action()) → R: Will notifyListeners after a specific action has been made, and optionally return a result R of certain type.
inherited
updateToNow() → DateTime: updates the current Watchers DateTime to Now and return it.

Operators

operator ==(Object other) → bool: The equality operator.
