You can get scripts and styles in your controller action with this code

ob_start();
ob_implicit_flush(false);
$this->view->beginPage();
$this->view->head();
$this->view->beginBody();
$this->renderPartial($view, $params);
$this->view->endBody();
$this->view->endPage(true);
$style_script= ob_get_clean();

and use $style_script in $spf_data

$spf_data = [
    'title' => Html::encode($this->title),
    'head' => $style_script,
    'body' => ['content' => $this->renderPartial('viewName')],
    "attr" => [
        'content' => [
            "class" => "container"
        ]
    ],
];

this code work for me
