W3 Total Cache plugin integration

I am working on a plugin (widget) that is using some transients that are updated from time to time.

That said, when these transients are updated, I think I will need to flush the cache to display the new data properly.

Thus, I wonder if have some way to flush the cache only for widget instead of entire cache. Do you guys have some advice?

if you want to flush the specific cache you can do that: the plugin has functions for that

<?php
flush_pgcache();  // Page cache
flush_dbcache();  // Database cache
flush_minify();  // Minify cache
flush_all(); // All caches
?>

and you just need to call it like this:

<?php 
$w3_plugin_totalcache->flush_all();
?>
