Methods

add(Duration duration) → DateTime?: Returns a new DateTime instance with duration added to this.
call(DateTime? value, {bool notifyChange = true, bool setAsOriginal = false}) → void: Updates the underlying value for this EmpireProperty.
inherited
compareTo(DateTime other) → int: Compares this DateTime object to other, returning zero if the values are equal.
difference(DateTime other) → Duration?: this.
equals(dynamic other) → bool: Checks if other is equal to the value of this EmpireProperty
inherited
isAfter(DateTime other) → bool: Returns true if this occurs after other.

noSuchMethod(Invocation invocation) → dynamic: Invoked when a nonexistent method or property is accessed.
inherited
reset({bool notifyChange = true}) → void: Resets the value to the originalValue.
inherited
set(DateTime? value, {bool notifyChange = true, bool setAsOriginal = false}) → DateTime?: Updates the property value. Notifies any listeners to the change
inherited

Static Methods

parse(String formattedString, {String? propertyName}) → EmpireNullableDateTimeProperty: Constructs a new EmpireNullableDateTimeProperty instance based on formattedString.
tryParse(String formattedString, {String? propertyName}) → EmpireNullableDateTimeProperty: Works like parse except that this function returns null where parse would throw a FormatException.
