Unable to use typed variables in a cell

Hi everyone!
I like using Cells in my project, especially the controlled ones. And I'd rather to use typed variables in my project.
But when i try to use typed peroperties in controlled cells, I get 

Code:

Undefined variable $typedVariable

Here is my code (I created a small project just for testing this)

Code:

JustATestCell.php

PHP Code:

<?php

namespace App\Cells;

use CodeIgniter\View\Cells\Cell;

class JustATestCell extends Cell
{
    public int $typedVariable;
} 


Code:

just_a_test.php

PHP Code:

<div>
    <?= $typedVariable; ?>
</div> 


Code:

main view file

PHP Code:

...
<?=    view_cell('JustATestCell', [
            'typedVariable' => 1
        ]);
    ?>
... 


So my question is: what am I doing wrong? Am I supposed not to use typed properties in cells?

Thanks in advance

How are you passing the variable to the view?

View Cells must return a string not an int.

What did you Try? What did you Get? What did you Expect?

As you can read here, those are made available automatically to the view file, because I'm using controlled cells

View Cells must return a string not an int.

As far as I can see, the Cell is returning a string, because it's returning the content of just_a_test.php.
But for the sake of the conversation, here is the modified version, returning the same error, which is:

Code:

Undefined variable $typedVariable

Code:

JustATestCell.php

PHP Code:

<?php

namespace App\Cells;

use CodeIgniter\View\Cells\Cell;

class JustATestCell extends Cell
{
    public string $typedVariable;
} 


Code:

just_a_test.php

PHP Code:

<div>
    <?= $typedVariable; ?>
</div> 


Code:

main view file

PHP Code:

<?=    view_cell('JustATestCell', [
            'typedVariable' => 'test'
        ]);
    ?>

Try:

PHP Code:

class JustATestCell extends Cell
{
    public $typedVariable;
} 


or

PHP Code:

class JustATestCell extends Cell
{
    public int $typedVariable = 0;
} 


This is due to the behavior of get_object_vars().

Try:

PHP Code:

class JustATestCell extends Cell
{
    public $typedVariable;
} 


or

PHP Code:

class JustATestCell extends Cell
{
    public int $typedVariable = 0;
}

This was pretty cool, good job, many thanks, much appreciated!
Could be useful then to use the Reflection API to improve this function?
I mean CodeIgniter\Traits\PropertiesTrait->getPublicProperties(), instead of relying on get_object_vars() should leverage the advantages of the Reflection API over get_object_vars()
