I already have this error:

Declaration of backend\models\Product::getPrice() must be compatible with yii2mod\cart\models\CartItemInterface::getPrice(): int

I already implement the CartInterface and functions and got this error

I added php version to be 7.3 in composer.json
and declared function like this:

public function getPrice() : int { return $this->price; }
