      Illuminate\Foundation\Console\Kernel::handle()

Here is the databaseseeder.php class since the error is there:

<?php

namespace Database\Seeders;

use App\Models\Category;
use App\Models\Product;
use App\Models\Transaction;
use App\Models\User;
use Illuminate\Database\Seeder;

use Illuminate\Support\Facades\DB;

class DatabaseSeeder extends Seeder
{
    /**
     * Seed the application's database.
     *
     * @return void
     */
    public function run()
    {
        // \App\Models\User::factory(10)->create();

        DB::statement('SET FOREIGN_KEY_CHECKS=0');

        User::truncate();
        Category::truncate();
        Product::truncate();
        Transaction::truncate();
        DB::table('category_product')->truncate();

        $cantidadUsuarios = 200;
        $cantidadCategories = 30;
        $cantidadProductos = 1000;
        $cantidadTransacciones = 1000;

        \App\Models\User::factory()->count($cantidadUsuarios)->create();
        \App\Models\Category::factory()->count($cantidadUsuarios)->create();

        \App\Models\Product::factory()->count($cantidadTransacciones)->create()->each                                                                                           (
            function ($producto) {
                $categorias = Category::all()->random(mt_rand(1, 5))->pluck('id');
                $producto->categories()->attach($categorias);
            }
        );

        \App\Models\Transaction::factory()->count($cantidadTransacciones)->create();
    }
}

There is the error line:

\App\Models\Category::factory()->count($cantidadUsuarios)->create();

Here we got the category class:

<?php

namespace App\Models;

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

class Category extends Model
{
    public $table = "categories";

    protected $fillable = [
        'name',
        'description',
    ];
}

Here we got the category factory:

<?php

namespace Database\Factories;

use App\Models\Category;
use Illuminate\Database\Eloquent\Factories\Factory;

class CategoryFactory extends Factory
{
    /**
     * The name of the factory's corresponding model.
     *
     * @var string
     */
    protected $model = Category::class;

    /**
     * Define the model's default state.
     *
     * @return array
     */
    public function definition()
    {
        return [
            //
             'name' => $this->faker->word,
            'description' => $this->faker->paragraph(1),
        ];
    }
}

Here is the category migration:

<?php

use App\Models\Product;
use Illuminate\Database\Migrations\Migration;
use Illuminate\Database\Schema\Blueprint;
use Illuminate\Support\Facades\Schema;

class CreateCategoriesTable extends Migration
{
    /**
     * Run the migrations.
     *
     * @return void
     */
    public function up()
    {
        Schema::create('categories', function (Blueprint $table) {
            $table->increments('id');
            $table->string('name');
            $table->string('description', 1000);
            $table->integer('quantity')->unsigned();
            $table->string('status')->default(Product::PRODUCTO_NO_DISPONIBLE);
            $table->string('image');
            $table->integer('seller_id')->unsigned();
            $table->timestamps();

            $table->foreign('seller_id')->references('id')->on('users');
        });
    }

    /**
     * Reverse the migrations.
     *
     * @return void
     */
    public function down()
    {
        Schema::dropIfExists('categories');
    }
}

I am posting all you need since I am new to this and I cannot find the problem.

As of Laravel 8, you need to use the factory trait for the model to have the factory() method available.

class Category extends Model
{
   use HasFactory;

   ...
}

add Trait to model => HasFactory

use Illuminate\Database\Eloquent\Factories\HasFactory;

class Model extends Model
{
    use HasFactory;
}

If at all you are using tinker, after adding Use HasFactory class, then simply end your current session and start another one.

- Ctr+c
- Php artisan tinker

if your using Laravel 8 Illuminate\Database\Eloquent\Factories\HasFactory is not there anymore, so just wrap your model class in factory() method instead

factory(App\Models\Category::class)->count($cantidadUsuarios)->create();

factory(App\Category::class)->count($cantidadUsuarios)->create();
