Storyboard

Faster iterative development of Flutter user interfaces by isolating widgets from your app, inspired by Storybook. Stage a collection of Widgets outside their normal app context. By repeating the same widget in various configurations or states in a single view, the effect of code changes to the Widget can quickly be assessed. This is especially useful for cosmetic changes, but also effective for behavior changes.

Adding Stories

The first step is to build a few stories, from which your Storyboard will be composed. Building stories is done by providing concrete children of the Story abstract class, e.g.

import 'package:mypackage/contacts.dart';
import 'package:storyboard/storyboard.dart';

class ContactsListStory extends Story {

  @override
  List<Widget> get storyContent {
    return [ContactsList()];
  }
}

At a minimum, the abstract storyContent getter, which provides the widgets to be observed, must be overridden. Overriding the title will alter the heading presented for the story. Overriding isFullScreen (or implementing FullScreenStory) will instruct the Widget to render itself within a new Navigator route without scaffolding.

The build method itself can also be overridden to completely customize the display of the Story.

Building a Storyboard

A storyboard is little more than a collection of stories.

import 'package:flutter/material.dart';
import 'package:storyboard/storyboard.dart';
import 'stories/contacts_story.dart';

void main() {
  runApp(MaterialApp(
      home: Storyboard([
        ContactsListStory(),
        ContactsCardStory(contact: Contact("alice")),
        ContactsCardStory(contact: Contact("bob")),
        ContactsCardStory(contact: Contact("charlie")),
  ])));
}

Or more simply, run the convenience StoryboardApp directly.

void main() {
  runApp(StoryboardApp([
    ContactsListStory(),
    ContactsCardStory(contact: Contact("alice")),
    ContactsCardStory(contact: Contact("bob")),
    ContactsCardStory(contact: Contact("charlie")),
  ]));
}
