Hey y'all. I'm working on upgrading to v3 as well. I am using the generator, but it's no longer generating the main.widgetbook.dart file when building, instead I get the error [SEVERE] widgetbook_generator:widgetbook_builder on lib/main.dart: Bad state: No element

I'm on versions

  widgetbook: ^3.0.0-beta.5
  widgetbook_annotation: 3.0.0-beta.3
  widgetbook_models: ^3.0.0-beta.1
  widgetbook_generator: ^3.0.0-beta.4

In main.dart I haven't changed the annotation code from the previous version:

@WidgetbookApp.material(
  name: 'rlly',
  devices: [
    Apple.iPhone13Pro,
    Apple.iPhone12Mini,
    Samsung.s10,
  ],
)

Verbose error:

Bad state: No element
dart:core                                                                                                              List.first

Here's my theme annotation in case that's relevant:

// Only used for widgetbook
@WidgetbookTheme(name: 'Light', isDefault: true)
ThemeData lightTheme() => ThemeData(
colorScheme: tealMagentaScheme,
primaryColor: const Color.fromRGBO(126, 110, 239, 1.0),
backgroundColor: const Color.fromRGBO(236, 0, 140, 1.0),
fontFamily: 'DM Sans',
canvasColor: RllyKnowledgeColors.background,
textTheme: textTheme);

That looks like a bug that we haven’t fixed yet. You probably have no locales defined.

The generator should work without locales but for now you can define some placeholders

Thanks for the help. Happy new year!

I tried adding

@WidgetbookLocales()
final locales = [
  const Locale('en'),
];

to main.dart and am having the same issue

Looks like adding

textScaleFactors: [
    2,
    3,
    4,
  ],

to @WidgetbookApp.material( did the trick

Oh, I think I'm running into the bug you were talking about now:

══╡ EXCEPTION CAUGHT BY WIDGETS LIBRARY ╞═══════════════════════════════════════════════════════════
The following ProviderNotFoundException was thrown building Builder(dirty, dependencies:
[_InheritedProviderScope?>]):
Error: Could not find the correct Provider above this Builder Widget

I'll try adding localization annotations

That worked!
