MySqlConnection.php

     * Blueprint resolver

        $builder = new MySqlBuilder($this);

MysqlServiceProvider.php

<?php

namespace App\Providers;

use Illuminate\Support\ServiceProvider;

/**
 * Class MysqlServiceProvider
 *
 * @package App\Providers
 */
class MysqlServiceProvider extends ServiceProvider
{
    
    /**
     * @see App\Database\MySqlConnection
     */
    public function register()
    {
        $this->app->bind('db.connection.mysql', App\Database\MySqlConnection::class);
    }
}

Thanks!!. how Can I extend the Schema the same way you did with the Blueprint??
I'm trying to do this:

 \DB::connection()->setSchemaGrammar(new ExtendedPostgresGrammar());
        $schema = \DB::connection()->getSchemaBuilder();
        $schema->blueprintResolver(function($table, $callback) {
            return new ExtendedBlueprint($table, $callback);
        });

        $schema->create('test_montos', function (ExtendedBlueprint $table) {
            $table->increments('id');
            $table->numeric('amount')->nullable(); // CUSTOM postgres type NUMERIC added in ExtendedBlueprint
            $table->decimal('amount');
            $table->timestamps();
        });

Can you give me hand please
