Coding Style Compatibility introduced by
PSR1 recommends that each class must be in a namespace of at least one level to avoid collisions.

You can fix this by adding a namespace to your class:

namespace YourVendor;

class YourClass { }

When choosing a vendor namespace, try to pick something that is not too generic to avoid conflicts with other libraries.

Since $instance is declared private, accessing it with static will lead to errors in possible sub-classes; consider using self, or increasing the visibility of $instance to at least protected.

Let’s assume you have a class which uses late-static binding:

class YourClass
{
    private static $someVariable;

    public static function getSomeVariable()
    {
        return static::$someVariable;
    }
}

The code above will run fine in your PHP runtime. However, if you now create a sub-class and call the getSomeVariable() on that sub-class, you will receive a runtime error:

class YourSubClass extends YourClass { }

YourSubClass::getSomeVariable(); // Will cause an access error.

In the case above, it makes sense to update SomeClass to use self instead:

class SomeClass
{
    private static $someVariable;

    public static function getSomeVariable()
    {
        return self::$someVariable; // self works fine with private.
    }
}

Documentation Bug introduced by
It seems like new static() of type this<WPAdminNotifications> is incompatible with the declared type object<Singleton> of property $instance.

Our type inference engine has found an assignment to a property that is incompatible with the declared type of that property.

Either this assignment is in error or the assigned type should be added to the documentation/type hint for that property..

Bug Compatibility introduced by
The expression static::$instance; of type WPAdminNotifications|Singleton adds the type WPAdminNotifications to the return on line 27 which is incompatible with the return type documented by WPAdminNotifications::get_instance of type Singleton.
