Run the generator
widgetbook_generator uses package:build_runner to generate the desired code.
You can execute the generator by running
flutter pub run build_runner build.
If you are making a lot of changes while developing, you can also run
flutter pub run build_runner watch so package:build_runner will listen for changes in the file system and update Widgetbook accordingly.
The generator will create the
app.widgetbook.dart file in the same directory as the file in which
@WidgetbookApp is used. For details about this, see the documentation of package:widgetbook_annotation.
Start the app by running
flutter run -t lib/app.widgetbook.dart -d macos.
