Using $get to get the state of parent form fields in repeaters

Hi all Is there a way of getting the state of a parent form field in a closure in a repeater field? Eg this doesn't work:

TextInput::make('title')
    ->live(),

Repeater::make('members')
    ->schema([
        TextInput::make('test')
            ->label(function (Get $get) {
                return $get('title');
            })
    ])

TextInput::make('title')
    ->live(),

Repeater::make('members')
    ->schema([
        TextInput::make('test')
            ->label(function (Get $get) {
                return $get('title');
            })
    ])

Weird, worked for us multiple times, like in this demo:

Forms\Components\Checkbox::make('multi_language') 
                    ->live()
                    ->columnSpanFull()
                    ->dehydrated(false)
                    ->formatStateUsing(fn (?Post $record) => (bool) $record?->title_translations)
                    ->disabled(fn (?Post $record, $context) => (bool) $record?->title_translations && $context == 'edit'), 
                Forms\Components\Repeater::make('title_translations')
                    ->hidden(fn (Forms\Get $get) => ! $get('multi_language'))

Forms\Components\Checkbox::make('multi_language') 
                    ->live()
                    ->columnSpanFull()
                    ->dehydrated(false)
                    ->formatStateUsing(fn (?Post $record) => (bool) $record?->title_translations)
                    ->disabled(fn (?Post $record, $context) => (bool) $record?->title_translations && $context == 'edit'), 
                Forms\Components\Repeater::make('title_translations')
                    ->hidden(fn (Forms\Get $get) => ! $get('multi_language'))

Have you tried it on a field inside the repeater's schema? It's working in fluent methods on the repeater itself. The problem is when trying to access parent field state in the repeater's sub-fields

Hmm good point it's a different case then, then maybe @Leandro Ferreira is right here
