  final name = TFieldProp<String>('');
  final email = TFieldProp<String>('');

  @override
  List<TFormField> get fields => [
    TFormField.text(name, 'Name', isRequired: true),
    TFormField.text(email, 'Email', isRequired: true),
  ];

  @override
  String get formTitle => 'Edit User';
}

final result = await TFormService.show(context, UserForm());
