Answer 1

Try this code instead of code at line 7

protected $getCurrentDate;

I think rest of the code was right.

Answer 2

what's your php version?

In PHP versions prior to 7.4, you cannot use type declarations for properties.

If you are using an older version of PHP, you can remove the type declaration for the property and instead add a type declaration for the parameter in the constructor.
