HubbleStepper class

A material stepper widget that displays progress through a sequence of steps. Steppers are particularly useful in the case of forms where one step requires the completion of another one, or where multiple steps need to be completed in order to submit the whole form.

The widget is a flexible wrapper. A parent class should pass currentStep to this widget based on some logic triggered by the three callbacks that it provides.

{@tool dartpad} An example the shows how to use the HubbleStepper, and the HubbleStepper UI appearance.

HubbleStepper({Key? key, required List<HubbleStep> steps, ScrollPhysics? physics, StepperType type = StepperType.vertical, int currentStep = 0, ValueChanged<int>? onStepTapped, VoidCallback? onStepContinue, VoidCallback? onStepCancel, ControlsWidgetBuilder? controlsBuilder, double? elevation, EdgeInsetsGeometry? margin})
Creates a stepper from a list of steps.
const

Properties

controlsBuilder → ControlsWidgetBuilder?
The callback for creating custom controls.
final
currentStep → int
The index into steps of the current step whose content is displayed.
final
elevation → double?
The elevation of this stepper's Material when type is StepperType.horizontal.
final
hashCode → int
The hash code for this object.
no setterinherited
key → Key?
Controls how one widget replaces another widget in the tree.
finalinherited
margin → EdgeInsetsGeometry?
custom margin on vertical stepper.
final
onStepCancel → VoidCallback?
The callback called when the 'cancel' button is tapped.
final
onStepContinue → VoidCallback?
The callback called when the 'continue' button is tapped.
final
onStepTapped → ValueChanged<int>?
The callback called when a step is tapped, with its index passed as an argument.
final
physics → ScrollPhysics?
How the stepper's scroll view should respond to user input.
final
runtimeType → Type
A representation of the runtime type of the object.
no setterinherited
steps → List<HubbleStep>
The steps of the stepper whose titles, subtitles, icons always get shown.
final
type → StepperType
The type of stepper that determines the layout. In the case of StepperType.horizontal, the content of the current step is displayed underneath as opposed to the StepperType.vertical case where it is displayed in-between.
