I have a custom widget, and inside it I need to retrieve the value of a field. How do I dynamically get a value for $widget_id?

class My_Widget extends WP_Widget {
// Widget output
	function widget( $args, $instance ) {

		$title = apply_filters( 'widget_title', $instance['title'] );

        echo $args['before_widget'] . $args['before_title'] . $title . $args['after_title'];

        the_field('field_name', 'widget_' . $widget_id);

        echo $args['after_widget'];
	}
}
