Typing properties if use docblocks can not work

[JimChenWYU]

In README.md an example

Or you can use docblocks:

class DateSettings extends Settings
{
    /** @var \DateTime  */
    public $birth_date;
    
    /** @var ?int  */
    public $a_nullable_int;
    
    public static function group(): string
    {
        return 'date';
    }
}

I always get an exception like:

Spatie\LaravelSettings\Exceptions\CouldNotResolveDocblockType
Could not resolve type in docblock: `int` of property `App\DateSettings::a_nullable_int`

when I try to look for the solution, I see the code and find this

$resolvedType = (new TypeResolver())->resolve($type);

if ($resolvedType instanceof Nullable) {
    return new Nullable(self::reflectDocblock(
        $reflectionProperty,
        (string) $resolvedType->getActualType()
    ));
}

when $type is ?int, or like other ?float, ?bool...
self::reflectDocblock() cannot be get actual type, alway call throw CouldNotResolveDocblockType::create($type, $reflectionProperty);

Hi @JimChenWYU,

This was a small bug that has been fixed in 2.1.1!

We've also added a new syntax:

class DateSettings extends Settings
{
    /** @var \DateTime  */
    public $birth_date;
    
    /** @var ?null  */
    public $a_nullable_int;
    
    /** @var int|null  */
    public $another_nullable_int;
    
    /** @var int[]|null  */
    public $an_array_of_ints_or_null;
    
    public static function group(): string
    {
        return 'date';
    }
}

This one feels a bit more natural
