 Use this code
 add_filter( 'render_block', function( $content, $block ) {
         static $is_even = true;

         if ( ! do_I_want_to_modify_this_block( $block ) ) {
                 return $content;
         }

         $is_even = ! $is_even;
         return sprint(
                 '<div class="%s">%s</div>',
                 $is_even ? 'is-even' : 'is-odd',
                 $content
         );
 } );
