Versions 2.0.0 of laravel-crud-wizard-decorator-free and version 7.1.0 of laravel-crud-wizard-free introduce an important response time improvement by eliminating useless json_decode and json_encode calls between the controller and the middlewares.
Because the controller resolves the JsonResponse from DI, the CrudProvider registers a binding for it in which the json_encode is skipped when the data needs decoration.
This follows Maravel-Framework s design of DI first logic and it works also in Laravel and Lumen.
