use Drupal\Core\Link;
$link = Link::createFromRoute('This is a link', 'entity.node.canonical', ['node' => 1]);
More flexibility with URL object
use Drupal\Core\Link;
use Drupal\Core\Url;
$link = Link::fromTextAndUrl('This is a link', Url::fromRoute('entity.node.canonical', ['node' => 1]));
Internal links which have no routes
$link = Link::fromTextAndUrl('This is a link', Url::fromUri('base:robots.txt'));
External links:
use Drupal\Core\Url;
use Drupal\Core\Link;
$link = !empty($url) ? Link::fromTextAndUrl($this->t('Newsletter'), Url::fromUri($url, [
'attributes' => [
'target' => '_blank',
'class' => ['button']

])) : '';
$html_link = $link->toString();
Using the data provided by a user
$link = Link::fromTextAndUrl('This is a link', Url::fromUserInput('/node/1');
Linking entities.
$link = Link::fromTextAndUrl('This is a link', Url::fromUri('entity:node/1'));
Drupal usually expects a render array if you are going to print the link, so the Link object has a method for that
$link->toRenderable();
Add links inside a t() method. Need to pass the link as a string.
$link = Link::fromTextAndUrl('This is a link', Url::fromRoute('entity.node.canonical', ['node' => 1]));
$this->t('You can click this %link' ['%link' => $link->toString()]);
