ActiveDouble class

An ActiveDouble with similar characteristics as a an ordinary dart double object. When an update is done an ActiveStateChanged event is triggered which in-turn makes a UI rebuild of that widget.

Has similar characteristics as double and The value cannot be null

Example


final amount = ActiveDouble(310.0);

print('${amount.add(0.10)}'); //prints 310.10

Properties

activeController → ActiveController
Returns the instance of the ActiveController this property is associated with.
no setterinherited
hashCode → int
The hash code for this object.
no setterinherited
isNegative → bool
A number is negative if it's smaller than zero, or if it is the double -0.0. This precludes a NaN value like double.nan from being negative.
no setter
isNotNull → bool
Returns true if the value of this is not null.
no setterinherited
isNull → bool
Returns true if the value of this is null.
no setterinherited
mockValue → double
no setterinherited
originalValue → double
no setterinherited
runtimeType → Type
A representation of the runtime type of the object.
no setterinherited
typeName ↔ String?
getter/setter pairinherited
value → double

Methods

add<E extends num>(E other) → double
Adds other to this number.
call(double value, {bool notifyChange = true, bool setAsOriginal = false}) → void
Updates the underlying value for this ActiveType.
inherited
divide<E extends num>(E other) → double
Divides this number by other.
equals(dynamic other) → bool
Checks if other is equal to the value of this ActiveType
inherited
mod<E extends num>(E other) → double
Euclidean modulo of this number by other.
multiply<E extends num>(E other) → double
Multiplies this number by 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
round() → int
Returns the integer closest to the double value.
roundToDouble() → double
Returns the integer double value closest to the double value.
set(double value, {bool notifyChange = true, bool setAsOriginal = false}) → double
Updates the property value. Notifies any listeners to the change
inherited
setActiveController(ActiveController activeController) → void
Links this ActiveType instance with an ActiveController.
inherited
setOriginalValueToCurrent() → void
Updates the original value to what the current value of this property is.
inherited
subtract<E extends num>(E other) → double
Subtracts other from this number.
toInt() → int
Truncates this num to an integer and returns the result as an int. Equivalent to truncate.Truncates the double value and returns the int
toString() → String
A string representation of this object.

Operators
