Insert value from one field to another

Hi, I would like to auto generate the email for my user form from the first and lastname. I tried this, but it didn't work:

            CreateAction::make()->form([
                Grid::make(2)->schema([
                    TextInput::make('firstname')
                             ->reactive()
                             ->required(),
                    TextInput::make('lastname')
                             ->reactive(),
                             ->required(),
                ]),
                TextInput::make('email')
                         ->suffix('@company.com')
                         ->default(fn($get) => $get('firstname') . '.' . $get('lastname'))
                         ->unique()
                         ->required()
            ]);

            CreateAction::make()->form([
                Grid::make(2)->schema([
                    TextInput::make('firstname')
                             ->reactive()
                             ->required(),
                    TextInput::make('lastname')
                             ->reactive(),
                             ->required(),
                ]),
                TextInput::make('email')
                         ->suffix('@company.com')
                         ->default(fn($get) => $get('firstname') . '.' . $get('lastname'))
                         ->unique()
                         ->required()
            ]);

How can I make this work? Thank you!

but how should this be done if there are two fields that should manipulate the email field (like in my example)? solved it like this now

                    TextInput::make('firstname')
                             ->reactive()
                             ->afterStateUpdated(function (Closure $set, $state, $get) {
                                 $set('email', strtolower($state) . '.' . strtolower($get('lastname')));
                             })
                             ->required(),
                    TextInput::make('lastname')
                             ->reactive()
                             ->afterStateUpdated(function (Closure $set, $state, $get) {
                                 $set('email', strtolower($get('firstname')) . '.' . strtolower($state));
                             })
                             ->required(),

                    TextInput::make('firstname')
                             ->reactive()
                             ->afterStateUpdated(function (Closure $set, $state, $get) {
                                 $set('email', strtolower($state) . '.' . strtolower($get('lastname')));
                             })
                             ->required(),
                    TextInput::make('lastname')
                             ->reactive()
                             ->afterStateUpdated(function (Closure $set, $state, $get) {
                                 $set('email', strtolower($get('firstname')) . '.' . strtolower($state));
                             })
                             ->required(),

But if theres a better way, please tell me 🙂

That's also how I do it, if the field needs to be editable. Otherwise a Placeholder is better if it's just for presentation.
