Did you try using get_field_objects()?
https://www.advancedcustomfields.com/resources/get_field_objects/
You could use a conditional to grab only Flexible Content fields:
<?php
if ($field['type'] == 'flexible_content') { // not sure if this is correct
/*
* get all custom fields and dump for testing
*/
$fields = get_field_objects();
var_dump( $fields );
/*
* get all custom fields, loop through them and create a label => value markup
*/
$fields = get_field_objects();
if( $fields )
{
foreach( $fields as $field_name => $field )
{
echo '<div>';
echo '<h3>' . $field['label'] . '</h3>';
echo $field['value'];
echo '</div>';
}
}
}
?>
