Access to an undefined property $form

Inside a custom component with a Filament form how to keep PhpStan happy with error:

Access to an undefined property $form

When I declare it

protected $form;

protected $form;

the fill method throws error:

Call to a member function fill() on null

Type hinting with form

$form must not be accessed before initialization

Solution

Add a phpdoc

/** @property Form $form */

/** @property Form $form */

to the class
