KnobsBuilder class abstract

Provides helper methods for creating knobs: control elements that can be used in stories to dynamically update its properties.

It's injected into a story builder, so you can use it there:

 Story(
   name: 'Flat button',
   builder: (_, k) => MaterialButton(
     onPressed: k.boolean('Enabled', initial: true) ? () {} : null,
     child: Text(k.text('Text', initial: 'Flat button')),
   ),
 )
