Answer 1

You can write it much shorter:

$node = $row->_entity;
if ($node->getType() == 'link') {
  $title = $node->title->value;
  $uri = $node->field_link->uri;

For the link field type the database column containing the field data is uri.

Answer 2

Well, I solved it by myself just now , I am not sure if this is the best way though, if you have a better way, it would be appreciated you can post it here.

my way:~

function showcontent_views_pre_render(ViewExecutable $view){


// Check if we are working with the correct view and display.
if ($view->id() == 'newest' ) {
    // Iterate through the rendered result to find the title field and rewrite it.

    foreach ($view->result as $key => $row) {
        dpm($row);

        if($row->_entity->hasField('field_link')){

            $current_title = $row->_entity->get('title')->value;
            dpm($current_title); //get node title
            $external_link_uri = $row->_entity->get('field_link')->first()->getValue()['uri'];   // this is the trick
            dpm($external_link_uri); //get uri value
  


        }else{

        }

    }

}
