run-script post-package-install - TypeError PackageEvent versus Event - bug in docu?

[siims-biz]

Regarding
https://getcomposer.org/doc/articles/scripts.md
The sample contains
"post-package-install": [
"MyVendor\MyClass::postPackageInstall"
],
public static function postPackageInstall(PackageEvent $event)

Observation
composer run-script post-package-install

Argument #1 ($event) must be of type Composer\Installer\PackageEvent, Composer\Script\Event given,

Composer version: 2.5.5
Windows 10

Is the sample working for you?

[Seldaek]

Yes, the sample works for me, with:

use Composer\Installer\PackageEvent;

    public static function postPackageInstall(PackageEvent $event)
    {
        $installedPackage = $event->getOperation()->getPackage();
        var_dump((string) $installedPackage);
    }

I get the following output when running install

  - Installing seld/jsonlint (1.9.0): Extracting archive
> MyVendor\MyClass::postPackageInstall
string(21) "seld/jsonlint-1.9.0.0"

So looks good to me..
