Custom widget not displaying ACF value

I’ve created a custom widget based on this code here. However when I try to display the ACF values in the front-end and they aren’t displaying. Am I supposed to be editing something in the ‘sanitize widget’ section?

/**
 * Adds custom widget.
 */

class Custom_Widget extends WP_Widget {

//Register widget with WordPress.
function __construct() {
    parent::__construct(
      'custom_widget', // Base ID
      __('Social Links', 'text_domain'), // Name
      array( 'description' => __( 'Social links for menu', 'text_domain' ), ) // Args
    );
}

//Front-end display of widget.
public function widget( $args, $instance ) {
    echo $args['before_widget'];?>
    <ul>
        <li><a href="<?php the_field('twitter_link', 'widget_' . $widget_id); ?>">twitter</a></li>
        <li></li>
    </ul>
    <?php echo $args['after_widget'];
}

//Back-end widget form.
public function form( $instance ) {

}

//Sanitize widget form values as they are saved.
public function update( $new_instance, $old_instance ) {
    $instance = array();
    $instance['title'] = ( ! empty( $new_instance['title'] ) ) ? strip_tags( $new_instance['title'] ) : '';

    return $instance;
    }
}

// register Custom_Widget widget
add_action( 'widgets_init', function(){
    register_widget( 'Custom_Widget' );
});

I’m adding my values using ACF, which you can see here:
