How to generate such a code?

[svfolder]

Hello.
Thank you very much for your work!
Can you tell me how to generate such a code?

                    [
                        'attribute' => 'brand_id',
                        'filter' => $searchModel->brandList(),
                        'value' => function (BrandAliasAssignment $model) {
                            return $model->getBrand()->one()->name;
                        },
                    ],

Thank you in advance!

    'value' => new Nette\PhpGenerator\PhpLiteral((string) $closure),
