Call to a Member Function cadastrarDados() on null - Laravel

Question

Good morning to all,

I am developing an application in Laravel 5.6 using PHP 7.2, I am having problems using DI(dependency Injection) in the constructor, since when creating the object manually the algorithm works perfectly, follows example:

THIS ONE DOESN’T WORK:

Centralcontroller

<?php

namespace App\Http\Controllers;
use App\Models\Central;

class CentralController extends BaseController
{

  protected $central;
  public function __construct(Central $central)
  {
    $this->central = $central;
  }

 public function centralParser(Request $request)
 {
 $this->central->cadastrarDados($request->all());
  ...
 }

Basecontroller

 namespace App\Http\Controllers;
 use App\Models\Usuario;

 class BaseController extends ResponseController
 {
  protected $usuario;
  public function __construct(Usuario $usuario)
  {
    $this->usuario = $usuario;
  }

  //metodos......
 }

---

This Works:

Centralcontroller

<?php

namespace App\Http\Controllers;
use App\Models\Central;

class CentralController extends BaseController
{

     public function centralParser(Request $request)
     {
     $central = new Central();
     $central->cadastrarDados($request->all());
      ...
     }
 }

Basecontroller

 namespace App\Http\Controllers;
 use App\Models\Usuario;

 class BaseController extends ResponseController
 {
  protected $usuario;
  public function __construct(Usuario $usuario)
  {
    $this->usuario = $usuario;
  }

  //metodos......
 }
