Default Scenario

Widgetbook creates a built-in Default scenario when a story has no defined scenarios.

How Args Are Picked

When Args are defined at the story level, they provide the initial values. The default scenario does not define its own args, so it inherits them from the story.

So whatever args you set at story level are used by the default scenario.

How Modes Are Picked

The default scenario does not define its own modes, so it inherits them from the story.

Practical Example

final $Button = _Story(
  args: _Args.fixed(
    label: 'Continue',
  ),
  modes: [
    MaterialThemeMode('Dark', ThemeData.dark()),
  ],
  // No scenarios here.
);

With no global scenario definitions in config, Widgetbook generates one scenario named Default. That scenario runs with these effective values:

Args

Modes
