BookingRangeSlider class

A widget which allows you to easily select booking/reservation ranges.

Usage example:

BookingRangeSlider(
              onChanged: (value) {
                print(value);
              },
              displayHandles: true,
              labelFrequency: TimeOfDay(hour: 1, minute: 0),
              initialTime: TimeOfDay(hour: 0, minute: 0),
              endingTime: TimeOfDay(hour: 6, minute: 0),
              values: <BookingValues>[
                BookingValues(
                  TimeOfDay(hour: 1, minute: 0),
                  TimeOfDay(hour: 2, minute: 0),
                ),
                BookingValues(
                  TimeOfDay(hour: 3, minute: 0),
                  TimeOfDay(hour: 3, minute: 30),
                ),
                BookingValues(
                  TimeOfDay(hour: 4, minute: 0),
                  TimeOfDay(hour: 5, minute: 0),
                  isAvailable: true,
                ),
                BookingValues(
                  TimeOfDay(hour: 5, minute: 30),
                  TimeOfDay(hour: 6, minute: 0),
                ),
              ],
            )

Methods

createElement() → LeafRenderObjectElement
RenderObjectWidgets always inflate to a RenderObjectElement subclass.
inherited
createRenderObject(BuildContext context) → RenderObject
Creates an instance of the RenderObject class that this RenderObjectWidget represents, using the configuration described by this RenderObjectWidget.
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.
override
didUnmountRenderObject(covariant RenderObject renderObject) → void
This method is called when a RenderObject that was previously associated with this widget is removed from the render tree. The provided RenderObject will be of the same type as the one created by this widget's createRenderObject method.
inherited
noSuchMethod(Invocation invocation) → dynamic
Invoked when a nonexistent method or property is accessed.
inherited
toDiagnosticsNode({String? name, DiagnosticsTreeStyle? style}) → DiagnosticsNode

inherited
toString({DiagnosticLevel minLevel = DiagnosticLevel.info}) → String
A string representation of this object.
inherited
toStringDeep({String prefixLineOne = '', String? prefixOtherLines, DiagnosticLevel minLevel = DiagnosticLevel.debug, int wrapWidth = 65}) → String
Returns a string representation of this node and its descendants.
inherited
toStringShallow({String joiner = ', ', DiagnosticLevel minLevel = DiagnosticLevel.debug}) → String
