Getting Started

class MyApp extends StatelessWidget {
  @override
  Widget build(BuildContext context) =>
      Storybook(
        children: [
          Story(
            name: 'Flat button',
            padding: EdgeInsets.all(5), // optional padding customization
            background: Colors.red, // optional background color customization
            builder: (_, k) =>
                MaterialButton(
                  onPressed: k.boolean(label: 'Enabled', initial: true) ? () {} : null,
                  child: Text(k.text(label: 'Text', initial: 'Flat button')),
                ),
          ),
          Story(
            name: 'Raised button',
            builder: (_, k) =>
                RaisedButton(
                  onPressed: k.boolean(label: 'Enabled', initial: true) ? () {} : null,
                  color: k.options(
                    label: 'Color',
                    initial: Colors.deepOrange,
                    options: const [
                      Option('Red', Colors.deepOrange),
                      Option('Green', Colors.teal),
                    ],
                  ),
                  textColor: Colors.white,
                  child: Text(k.text(label: 'Text', initial: 'Raised button')),
                ),
          ),
          Story.simple(
            name: 'Input field',
            child: const TextField(
              decoration: InputDecoration(
                border: OutlineInputBorder(),
                labelText: 'Input field',
              ),
            ),
          ),
        ],
      );
}

Customization

By default, each story is wrapped into:

Container(
  color: story.background,
  padding: story.padding,
  child: Center(child: child),
)

You can override this behavior by providing either wrapperBuilder to the Story or storyWrapperBuilder to the Storybook. In the latest case this wrapper will be applied to each story (of course, you can still override this behavior by providing another wrapperBuilder to individual stories).

CustomStorybook

If you need even more customization, you can use CustomStorybook. You have to provide builder parameter to it where you can define the custom layout. In this case you're responsible for rendering the story, contents and knobs panel.

You can use CurrentStory, Contents and KnobPanel widgets that will render the corresponding data automatically.

As an example of full customization, take a look at storybook_device_preview package that allows to embed storybook into device_preview package with knobs and contents rendered as plugins.
