NesIterableOptions<T> class

A widget that allows users to cycle through options.

By default, the indicator of the selected option is value.toString() inside a Text widget. That can be customized by informing a optionBuilder.

The default selection controllers are NesIconCollection.leftArrowIndicator and NesIconCollection.rightArrowIndicator, that can be also be customized by passing a leftIndicatorBuilder and rightIndicatorBuilder.
