<?php

class DemoFile
{
    public function __construct(
        private readonly ?string $demoField1,
        private readonly ?string $demoField2,
    ) {}
    
    public function getData(): array 
    {
        $data = [];
        if ($this->demoField2 !== null) {

        }
        
        return $data;
    }
}
