Properties

currentStep int
Index that is active for the surrounding Stepper widget. This may be different from stepIndex if the user has just changed steps and we are currently animating toward that step.
final
hashCode int
The hash code for this object. [...]
read-only, inherited
isActive bool
True if the indicated step is also the current active step. If the user has just activated the transition to a new step, some Stepper.type values will lead to both steps being rendered for the duration of the animation shifting between steps.
read-only
onStepCancel VoidCallback?
The callback called when the 'cancel' button is tapped. [...]
final
onStepContinue VoidCallback?
The callback called when the 'continue' button is tapped. [...]
final
runtimeType Type
A representation of the runtime type of the object.
read-only, inherited
stepIndex int
Index of the step for which these controls are being built. This is not necessarily the active index, if the user has just changed steps and this step is animating away. To determine whether a given builder is building the active step or the step being navigated away from, see isActive.
final
