Set value of another field from within default

Can I set the value of the key from within the default of the name. Ideally I don't want to duplicate the logic fetching the default name.

Forms\Components\TextInput::make('name')
    ->afterStateUpdated(function (\Closure $set, ?string $state):void {
        $set('key', Str::slug($state));
    })
    ->default(function (\Closure $set): string {
        $name = 'Complicated logic';
        $set('key', Str::slug($name));
        return $name;
    })
    ->reactive()
    ->required(),

Forms\Components\TextInput::make('key'),

Forms\Components\TextInput::make('name')
    ->afterStateUpdated(function (\Closure $set, ?string $state):void {
        $set('key', Str::slug($state));
    })
    ->default(function (\Closure $set): string {
        $name = 'Complicated logic';
        $set('key', Str::slug($name));
        return $name;
    })
    ->reactive()
    ->required(),

Forms\Components\TextInput::make('key'),

If you put the key input first it works. I think the default is getting called before all the fields are registered is there a way around this?

Possibly afterStateHydrated() instead of default()

Tried that but unfortunately the key value is not getting set. I'm using those fields inside createOptionForm and I don't think there's an afterFill hook equivalent.

lol, I was just going to suggest afterFill Can you subclass the Select field and override getCreateOptionAction()? I think you would be able to add a afterFormFilled() hook to it

You've led me to modifyCreateOptionActionUsing just going to see if I can get that working. That wasn't working but I figured I could get the value instead. Spent too long trying to get it to work the other way around.

Forms\Components\TextInput::make('key')
    ->default(fn (\Closure $get) => Str::slug($get('name')))

Forms\Components\TextInput::make('key')
    ->default(fn (\Closure $get) => Str::slug($get('name')))
