IconStepper

A simple to use icon stepper widget, wherein, each icon defines a step. Hence, total number of icons define total number of steps. Primarily designed to show steps as icons.

IconStepper - Usage Note

• Important: IconStepper direction argument controls whether the stepper is displayed horizontally or vertically. A horizontal IconStepper can be wrapped within a Column with no issues, however, if wrapped within a row it must also be wrapped within the built-in Expanded widget. Same applies for the vertical IconStepper.

• IconStepper fires the onStepReached(int index) callback, which provides the index of the Step that is reached. This callback can be used to control the widget that appears when a certain step is reached.

• To customize the color, border, etc. of an IconStepper, simply wrap it inside a Container and specify the decoration argument.

• To enable validation before the next step is reached, set the steppingEnabled property to an appropriate value in a StatefulWidget.

• Github issues #3 and #4 stand resolved. To control the IconStepper, ImageStepper, or the NumberStepper by using buttons etc from outside the stepper, use the Foo.externallyControlled() constructor and call goNext and goPrevious controlled by two variables in a StatefulWidget within a setState call.
