What is the right way of using AllowList. I am trying to use it as follows. My question is how do I pass the list of values.

       $inputFilter->add([
           'name'     => 'my-dsc-type',
           'required' => true,
           'allow_empty' => false,
           'filters'  => [
               [
                   'name' => AllowList::class,
                   'list' => ['1','2'],
               ],   

           ],                
           
       ]);

I think it is:

$inputFilter->add([
           'name'     => 'my-dsc-type',
           'required' => true,
           'allow_empty' => false,
           'filters'  => [
               [
                   'name' => new AllowList(['1','2'])
               ],   

           ],                
           
       ]);

You can use an options key for every filter in your configuration.

inputFilter->add([
    'name'     => 'my-dsc-type',
    'required' => true,
    'allow_empty' => false,
    'filters'  => [
        [
            'name' => AllowList::class,
            'options' => [
                'list' => ['1', '2'],
                'strict' => true,
            ],
        ],   
    ],                       
]);

… or as constructor parameter:

$allowList = new \Laminas\Filter\AllowList([
    'list' => ['allowed-1', 'allowed-2']
]);
echo $allowList->filter('allowed-2');   // => 'allowed-2'
echo $allowList->filter('not-allowed'); // => null

Last example taken from the official laminas documentation.
