在函数中传递参数

Question

I am trying to refactor a subset of my code as practice and since I am new at Sonata. I am making a silly mistake but I am stuck at reconciling my mistake:

public function getIsActiveThisYear(EndDate $endDate,StartDate $startDate): bool
 {
     return  $this->$endDate == $date->isCurrentYear() || $this->$startDate == $date->isCurrentYear();
 }

I am receiving the following error: No arguments passed. Keep in mind while answering this question I could be making an obvious mistake or doing it all wrong; a good description will help me learn. Thanks!

This is the full error

1) App\Tests\Entity\ProjectTest::testProjectEndsSameYearIsActiveThisYear
