HubbleStepper constructor

const HubbleStepper({
  1. Key? key,
  2. required List<HubbleStep> steps,
  3. ScrollPhysics? physics,
  4. StepperType type = StepperType.vertical,
  5. int currentStep = 0,
  6. ValueChanged<int>? onStepTapped,
  7. VoidCallback? onStepContinue,
  8. VoidCallback? onStepCancel,
  9. ControlsWidgetBuilder? controlsBuilder,
  10. double? elevation,
  11. EdgeInsetsGeometry? margin,
})

Creates a stepper from a list of steps.

This widget is not meant to be rebuilt with a different list of steps unless a key is provided in order to distinguish the old stepper from the new one.

The steps, type, and currentStep arguments must not be null.

Implementation

const HubbleStepper({
  Key? key,
  required this.steps,
  this.physics,
  this.type = StepperType.vertical,
  this.currentStep = 0,
  this.onStepTapped,
  this.onStepContinue,
  this.onStepCancel,
  this.controlsBuilder,
  this.elevation,
  this.margin,
})  : assert(steps != null),
      assert(type != null),
      assert(currentStep != null),
      assert(0 <= currentStep && currentStep < steps.length),
      super(key: key);
