The border color of a step when it is reached.
final
- activeStepBorderPadding → double
-
Determines how far away the border should be drawn from the step when it is reached.
final
- activeStepBorderWidth → double
-
The border width of the active step.
final
- activeStepColor → Color?
-
The color of a step when it is reached.
final
- alignment → AlignmentGeometry
-
Specifies the alignment of the NumberStepper.
final
- direction → Axis
-
Whether to show the steps horizontally or vertically. Note: Ensure horizontal stepper goes inside a column and vertical goes inside a row.
final
- enableNextPreviousButtons → bool
-
Whether to enable or disable the next and previous buttons.

-
Controls how one widget replaces another widget in the tree.
finalinherited
- lineColor → Color?
-
The color of the line that separates the steps.
final
- lineDotRadius → double
-
