The expression $integer - $value; of type integer|double adds the type double to the return on line 94 which is incompatible with the return type declared by the interface Illuminate\Contracts\Cache\Store::decrement of type integer|boolean.

$initialize is not used, you could remove the assignment.

The expression $remains of type integer|null is loosely compared to true; this is ambiguous if the integer can be zero. You might want to explicitly use !== null instead.
