InputBag::get() method incorrectly reports type error for bool default parameter

[sfmok]

PHPStan is incorrectly reporting a type error when using false as the default parameter for Symfony\Component\HttpFoundation\InputBag::get() method.

The error states that the method expects string|null but false is given, which is incorrect according to the actual method signature.

PHPStan reports the following error:

Parameter #2 $default of method Symfony\Component\HttpFoundation\InputBag<string>::get() expects string|null, false given.

Code Example

use Symfony\Component\HttpFoundation\Request;

$request = new Request();
$isPreview = $request->query->get('preview', false); // This triggers the error

Environment Details

• PHPStan Version: 1.12.25
• PHPStan Symfony Extension: 1.4.15
• Symfony Version: 6.4.*
• PHP Version: 8.2.20

The actual InputBag::get() method signature is:

/**
 * Returns a scalar input value by name.
 *
 * @param string|int|float|bool|null $default The default value if the input key does not exist
 */
public function get(string $key, mixed $default = null): string|int|float|bool|null
{
    if (null !== $default && !\is_scalar($default) && !$default instanceof \Stringable) {
        throw new \InvalidArgumentException(sprintf('Expected a scalar value as a 2nd argument to "%s()", "%s" given.', __METHOD__, get_debug_type($default)));
    }

    $value = parent::get($key, $this);

    if (null !== $value && $this !== $value && !\is_scalar($value) && !$value instanceof \Stringable) {
        throw new BadRequestException(sprintf('Input value "%s" contains a non-scalar value.', $key));
    }

    return $this === $value ? $default : $value;
}

This appears to be an issue with PHPStan's Symfony extension having an outdated or incorrect type definition for the InputBag::get() method. The extension seems to be using an older type definition that doesn't match the current Symfony implementation.
