ControlsDetails class Null safety
Container for all the information necessary to build a Stepper widget's forward and backward controls for any given step.
Used by Stepper.controlsBuilder.
- 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.
- hashCode → int
The hash code for this object.
- 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
- onStepCancel → VoidCallback?
The callback called when the 'cancel' button is tapped.
- onStepContinue → VoidCallback?
The callback called when the 'continue' button is tapped.
- runtimeType → Type
A representation of the runtime type of the object.
- 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.
