Update viewfield state with placeholder addition values

Hello everyone, I wish update a viewfield state with dynamic placeholder values operation (the last line of the screenshot).

Forms\Components\Placeholder::make('vcpu_cost')
    ->content(fn (Get $get): string => Number::currency(
        Vcpu::where('id', '=', $get('vcpu_id'))
        ->first()->price,
        'EUR',
        App::currentLocale())
    ),
Forms\Components\Placeholder::make('ram_cost')
    ->content(fn (Get $get): string => Number::currency(
        Ram::where('id', '=', $get('ram_id'))
            ->first()->price,
        'EUR',
        App::currentLocale())
    ),
Forms\Components\Placeholder::make('disk_space_cost')
    ->content(fn (Get $get): string => Number::currency(
        $get('disk_space_cost_per_go') * (int) $get('disk_space'),
        'EUR',
        App::currentLocale())
    ),
Forms\Components\ViewField::make('total_cost')
    ->label(__('vmc.total_cost'))
    ->disabled()
    ->inlineLabel()
    ->view('filament.forms.components.horizontal-label-price'),
    // I think I have to add something here...

        'EUR',
        App::currentLocale())
    ),

        Ram::where('id', '=', $get('ram_id'))

    ->disabled()
    ->inlineLabel()
    ->view('filament.forms.components.horizontal-label-price'),
    // I think I have to add something here...

How can I afford this?

You probably want to work with the state or the record and do your calculations! 🤔

$getRecord can only provide "real" inputs value, but not placeholders values. I'm trying to find a workaround and use hidden fields instead right now, but my hidden fields won't update, I don't know why (but I'm working on it) I don't know how update my viewField state as soon as juste one of the three fields are updated There is nothing simpler than using afterStateUpdated() and afterStateHydrated() on all my fields ? I mean, on placeholders, you can juste use the content() method with a Closure and it will be updated as soon as a live() field is updated. Can't we do the same on viewField, or maybe other fields ?
