Need page of child pages (with Flutter involved)

Hi,

I am using Flutter to create real estate listing pages.

But, I’m not able to find out how to have a parent page (ex. “My Listings) that shows a list of the individual listings (with a thumbnail and property description) and have the child pages be the individual property pages.

I have the code:

<?php
  if($post->post_parent)
  $children = wp_list_pages("title_li=&child_of=".$post->post_parent."&echo=0");
  else
  $children = wp_list_pages("title_li=&child_of=".$post->ID."&echo=0");
  if ($children) { ?>
  <--//ul>
  <?php echo $children; ?>
  </ul//-->

<?php } ?>

But that only shows text links, and I’m not sure how to incorporate my flutter data here.

Thoughts?
