Use DI for translatable strings instead of global t().

Hello,

The t() function is still present in Drupal 8, as it was in Drupal 7. I suggest to replace t() function with $this->t().

This means that in most Drupal 8 object-oriented code (controllers, listeners, plugins, forms etc.), instead of using the global t() function, you should instead use dependency injection.

If there is no suitable base class for your task with a t() method, you can use the StringTranslationTrait to get t() and formatPlural() methods.

Thanks,
Nitin
