Is there a way to avoid duplicate afterStateUpdated methods ?

the callback will be 'busy' ; but i can separate that out main thing is it's defined once; so it should be less brittle / easier to keep in good shape

Is there a way to avoid duplicate afterStateUpdated methods ?

and..... simplest of all....

 \Filament\Forms\Components\Section::make()
                    ->columns([
                        'default' => 1,
                        'sm' => 2,
                        'lg' => 3,
                    ])
                    ->schema([

                TextInput::make('number 1')
                    ->live()
                    ->numeric(),
                TextInput::make('number 2')
                    ->live()
                    ->numeric(),
                TextInput::make('total')
                    ->numeric()
            ])->afterStateUpdated(function (Get $get, Set $set): void {
                $set('total', (int)$get('number 1') + (int)$get('number 2'));
            }),

i think for my situation, it may be worth taking the hackiness here; my afterStateUpdateds are quite intertwined.... it's not just field 3 depends on field 1 and field 2 more field a depends on field 1,2,3 field b depends on 1 + 4 field c depends on 2 so extracting out a closure is still messy defining the callbacks on the target field rather than the source field is a whole load cleaner/nicer to work with

this works... first, override on the page/livewire component:

    public function updatedInteractsWithForms(string $statePath): void
    {
        parent::updatedInteractsWithForms($statePath);
        $this->dispatchFormEvent('my-special-event');
    }

    public function updatedInteractsWithForms(string $statePath): void
    {
        parent::updatedInteractsWithForms($statePath);
        $this->dispatchFormEvent('my-special-event');
    }

then a field can listen for that event

                TextInput::make('number 1')
                    ->live()
                    ->numeric(),
                TextInput::make('number 2')
                    ->live()
                    ->numeric(),
                TextInput::make('total')
                    ->numeric()
                ->registerListeners([
                    'my-special-event' => [function (Component $component): void {

                        $set = new Set($component);
                        $get = new Get($component);

                        $set('total', $get('number 1') + $get('number 2'));
                    }],
                ]),

                TextInput::make('number 1')
                    ->live()
                    ->numeric(),
                TextInput::make('number 2')
                    ->live()
                    ->numeric(),
                TextInput::make('total')
                    ->numeric()
                ->registerListeners([
                    'my-special-event' => [function (Component $component): void {

                        $set = new Set($component);
                        $get = new Get($component);

                        $set('total', $get('number 1') + $get('number 2'));
                    }],
                ]),

kind of dirty/hacky
