afterStateHydrated() doesn't work?
When I try to use the example from the documentation, I get an error. What am I doing wrong?
TypeError
App\Filament\Resources\TestResource::App\Filament\Resources\{closure}(): Argument #2 ($state) must be of type string, null given, called in ......./vendor/filament/support/src/Concerns/EvaluatesClosures.php on line 35

?string $state$state should typically be typed as mixed.
Because it could technically be anything.
OK, I was doing a copy/paste from the documentation so it's a small bug in the documentation?
This example already with the fix (?string) causes the "name" field to change only during initialization (so when the form is read from the database). After changing this field manually, nothing happens. Is this how afterStateHydrated() works?
Back to this topic I'm stuck on:

...this code also does not make the total field change every time the qty or price changes:
return $form
->schema([
TextInput::make('qty')->live(),
TextInput::make('price')->live(),
TextInput::make('total')
->required()
->afterStateHydrated(function (Get $get, TextInput $component) {
$component->state($get('qty') * $get('price'));
})
]);
Should this work or am I still doing something wrong?
