Get current JetEngine listing object meta value ( somewhat similar to ACF get_field() )

get-meta.php

<?php

//You may just use get_post_meta() to get post/term/user meta
//However, in Listing Grid, you may use get_meta() method for convenience

$value = jet_engine()->listings->data->get_meta( $meta_key, $object );

/**
 * Get object meta value. Works for Posts, Terms, Users, Comments
 * $object defaults to null, then the value will be retrieved from the current listing object
 * Example: the current object is a Post, 
 * the meta key is 'age'
 * the meta value is 42
 */
$value = jet_engine()->listings->data->get_meta( 'age' );
//$value is 42

/**
 * To get the value from the post, different from the current listing object, pass that object as the second argument
 * Example: post ID is 512
 * the meta key is 'age'
 * the meta value is 24
 * Current listing post 'age' meta value is 48
 */
 $object = get_post( 512 );
 $value  = jet_engine()->listings->data->get_meta( 'age', $object );
 //$value is 24, as we get meta value from $object, which is a post with ID of 512
