ZetaStepper class Components
Zeta 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 steppers current step is managed through the currentStep property. To change it, store this value in state and change it with the onStepTapped callback. The stored value can then be used to update content depending on the selected step.
ZetaStepper(
steps: [
ZetaStep(title: Text('Step 1')),
ZetaStep(title: Text('Step 2')),
ZetaStep(title: Text('Step 3')),
],
currentStep: currentStep,
onStepTapped: (step) {
setState(() {
currentStep = step;
});
},
)

Properties
- currentStep → int
-
The index into steps of the current step whose content is displayed.
final
- hashCode → int
-
The hash code for this object.
no setterinherited
- key → Key?
-
Controls how one widget replaces another widget in the tree.
finalinherited
-
onStepTapped
→ ValueChanged<
int> ? -
The callback called when a step is tapped, with its index passed as
an argument.
final
- rounded → bool?
-
Sets rounded or sharp border of the containing box and the icon style.
finalinherited
- runtimeType → Type
-
A representation of the runtime type of the object.
no setterinherited
-
steps
→ List<
ZetaStep> -
The steps of the stepper whose titles, subtitles, icons always get shown.
final
- type → ZetaStepperType
-
The type of stepper that determines the layout. In the case of
ZetaStepperType.horizontal, the content of the current step is displayed
underneath as opposed to the ZetaStepperType.vertical case where it is
displayed in-between.
