$imoveis is Undefined, indefinite variable in Blade

Question

The variable $imoveis in Blade is undefined, for me it is correct in the code.

@extends('layouts.main')

@section('title', 'Web Room')

@section('content')

<h1>Imoveis web</h1>

  <div id="search-container" class="col-md-12">
     <h1>Busque um imóvel</h1>
     <form action="">
         <input type="text" id="search" name="search" class="form-control" placeholder="Procure um imóvel..">
     </form>
  </div>
  <div id="imoveis-container" class="col-md-12">
      <h2>Próximos Imoveis</h2>
      <p>Veja os eventos dos proximos dias</p>
      <div id="cards-container" class="row">
      @foreach($imoveis as $imovel)
        <div class="card-col-md-3">
            <img src="/img/banner.jpg" alt="{{$imovel->titulo}}">
            <div class="card-body">
            <p class="card-date">10/09/2021</p>
            <h5 class="card-title">{{$imovel->titulo}}</h5>
            <p class="card-participantes">x participantes</p>
            <a href="#" class="btn btn-primary">Saber mais</a>
        </div>
  </div>
@endforeach
</div>
@endsection

Controller

<?php

namespace App\Http\Controllers;

use Illuminate\Http\Request;
use App\Models\Imovel;

class ImoveisController extends Controller
{
    public function index(){

        $imoveis = Imovel::all();
        dd($imoveis);

        return view('welcome', ['imoveis' => $imoveis]);

    }

    public function create(){
        
        return view('imoveis.create');
    }
}

Model

<?php

namespace App\Models;

use Illuminate\Database\Eloquent\Factories\HasFactory;
use Illuminate\Database\Eloquent\Model;

class Imovel extends Model
{
    use HasFactory;

    protected $table = "imoveis";

    protected $fillable = ['titulo','descricao','valor_aluguel','endereco'];
}

In function index() class ImoveisController try passing the properties to the view with the function compact() that way:

return view('welcome', compact('imoveis'));

The compact() makes a kind of structuring through the label of the variable and you can use in Blade with the same label name $imoveis:

example:

$names = ['Jon Snow', 'Aerys Targaryen']; 

$compacted = compact('names');

//saída de print_r($compacted); 

Array
(
    [names] => Array
        (
            [0] => Jon Snow
            [1] => Aerys Targaryen
        )

)
//saída de print_r($compacted['names']);
Array
(
    [0] => Jon Snow
    [1] => Aerys Targaryen
)
