        $this->fileData = $fileData;

It seems like $fileData of type array is incompatible with the declared type string of property $fileData.

        $this->config = $config;

        foreach ($this->fileData as $line) {

The expression $this->fileData of type string is not traversable.

            if (!empty($line)) {
                $row = array();
                $start = 0;
                foreach ($this->config as $field => $length) {
                    $row[$field] = trim(substr($line, $start, $length));
                    $start += $length;
                }
                $return[] = $row;
            }
        }
