localizationMiddleware function

Middleware localizationMiddleware(LocaleManager manager)

Middleware that resolves and stores the active locale for each request.

Creates middleware that runs the LocaleManager before downstream handlers.

The resolved locale is stored under kRequestLocaleAttribute so helpers such as trans can pick it up.

Implementation

Middleware localizationMiddleware(LocaleManager manager) {
  return (EngineContext ctx, Next next) async {
    final context = LocaleResolutionContext.fromContext(ctx);
    final locale = manager.resolve(context);
    ctx.set(kRequestLocaleAttribute, locale);
    return await next();
  };
}
