NumberSelection class
the concept of the widget inspired from Nikolay Kuchkarov. and thanks to Raouf Rahiche for starting this
- Inheritance

- Object
- DiagnosticableTree
- Widget
- StatefulWidget
- NumberSelection
Constructors
-
NumberSelection({Key? key, int? initialValue, ValueChanged<
int> ? onChanged, Function? onOutOfConstraints, bool enableOnOutOfConstraintsAnimation = true, Axis direction = Axis.horizontal, bool withSpring = true, int maxValue = 100, int minValue = -100, NumberSelectionTheme? theme}) -
const
Properties
- direction → Axis
-
the orientation of the stepper its horizontal or vertical.
final
- enableOnOutOfConstraintsAnimation → bool
-
Enable the color and boomerang animation when user try to change value to
a value that is superior as maxValue or inferior as minValue
final
- hashCode → int
-
The hash code for this object.
no setterinherited
- initialValue → int?
-
the initial value of the stepper
final
- key → Key?
-
Controls how one widget replaces another widget in the tree.
finalinherited
- maxValue → int
-
maximum of the value it can reach
defaults is 100
final
- minValue → int
-
minimum on the value it can be
defaults is -100
final
-
onChanged
→ ValueChanged<
int> ? -
called whenever the value of the stepper changed
final
- onOutOfConstraints → Function?
-
called when user try to change value to a value that is superior as
maxValue or inferior as minValue
final
- runtimeType → Type
-
A representation of the runtime type of the object.
no setterinherited
- theme → NumberSelectionTheme?
-
Theme of the NumberSelection widget:
final
- withSpring → bool
-
if you want a springSimulation to happens the the user let go the stepper
defaults to true
final
Methods
-
createElement(
) → StatefulElement -
Creates a StatefulElement to manage this widget's location in the tree.
inherited
-
createState(
) → _NumberSelectionState -
Creates the mutable state for this widget at a given location in the tree.
override
-
debugDescribeChildren(
) → List< DiagnosticsNode> -
Returns a list of DiagnosticsNode objects describing this node's
children.
inherited
-
debugFillProperties(
DiagnosticPropertiesBuilder properties) → void -
Add additional properties associated with the node.
inherited
-
noSuchMethod(
Invocation invocation) → dynamic -
Invoked when a nonexistent method or property is accessed.
inherited
-
toDiagnosticsNode(
{String? name, DiagnosticsTreeStyle? style}) → DiagnosticsNode -
Returns a debug representation of the object that is used by debugging
tools and by DiagnosticsNode.toStringDeep.
inherited
-
toString(
{DiagnosticLevel minLevel = DiagnosticLevel.info}) → String -
A string representation of this object.
inherited
-
toStringDeep(
{String prefixLineOne = '', String? prefixOtherLines, DiagnosticLevel minLevel = DiagnosticLevel.debug}) → String -
Returns a string representation of this node and its descendants.
inherited
-
toStringShallow(
{String joiner = ', ', DiagnosticLevel minLevel = DiagnosticLevel.debug}) → String -
Returns a one-line detailed description of the object.
inherited
-
toStringShort(
) → String -
A short, textual description of this widget.

Operators
-
operator ==(
Object other) → bool -
