+/// [BrandBloc] is a Bloc responsible for managing the brand state.
+/// 
+/// This Bloc listens for [BrandEvent]s and updates the [BrandState]
+/// accordingly.
+/// The [BrandState] can be consumed by the [MaterialApp] to build the 
+/// appropriate [ThemeData] based on the [BrandKey] stored in the state.
+/// 
+/// To build the appropriate [ThemeData] based on the [BrandKey] is
+/// possible to use the [ThemeBuilder] utility form the `catalyst_voices_brands`
+/// package.
+///
+/// The [BrandChangedEvent] accepts a [BrandKey] a simple enum that
+/// contains all possible brands/themes.
+/// 
+/// To trigger the theme change is just necessary to dispatch the
+/// [BrandChangedEvent] with the appropriate key:
+///
+/// ```dart
+/// context.read<BrandBloc>().add(
+///   const BrandChangedEvent(BrandKey.catalyst),
+/// );
+/// ```
+///
+/// Usage example:
+///
+/// ```dart
+/// BlocProvider(
+///   create: (context) => BrandBloc(),
+///   child: BlocBuilder<BrandBloc, BrandState>(
+///     builder: (context, state) {
+///       return MaterialApp(
+///         home: Builder(
+///           builder: (context) => Scaffold(
+///             body: Row(
+///               children: [
+///                 MaterialButton(
+///                   color: Theme.of(context).primaryColor,
+///                   onPressed: () {
+///                     context.read<BrandBloc>().add(
+///                       const BrandChangedEvent(BrandKey.catalyst),
+///                     );
+///                   },
+///                   child: const Text('Switch to Catalyst Theme'),

+///             ),
+///           ),
+///         ),
+///         theme: ThemeBuilder.buildTheme(state.brandKey),
+///       );
