PdfCreator method error

[juggernautsei]

Describe the bug

write concise description of what the bug is.
Method returns undefined variable

To Reproduce

public function write($html_file, $save_to, $options)
{
    $pdfwk = new Pdf($this->binaryPath);
    $pdfwk->generateFromHtml(file_get_contents($html_file), $save_to);

    return **$pdfFilePath;**
}

Expected behavior

The $pdfFilePath; should be defined from within the method or passed into the method. At least that is what I was thinking. PHPStan reports the same issue.
