The following code can be placed at the bottom of your functions.php document. It will loop through all your posts within that post type and set fl_flag to 1/true. You can delete it after viewing any page once. If the field fl_flag does not exist in the post it will create the field.

$args=array(
	'posts_per_page' => -1,
	'post_type' => 'events'
);
$the_query = new WP_Query( $args );
if ( $the_query->have_posts() ) :
	while ( $the_query->have_posts() ) : $the_query->the_post();
		update_field('fl_flag', '1', get_the_ID());
	endwhile;
endif;
