[version-4.3.3] value not exists in SmartSelect<String>.single function

[RebaekSoparkKitchen]

Hi,

I am happy to see this package has been upgraded to 4.3.3 which is a null-safety version. However, after changes, I have checked that the function SmartSelect<String>.single in previous version can take parameter value, which in new version is not supported.

Also, in onChange function, state.valueDisplay is not supported.
example:

SmartSelect<String>.single(
      title: '业务经理',
      value: controller.contact.value,
      choiceItems: controller.staffOptions,
      modalType: S2ModalType.bottomSheet,
      modalConfig: S2ModalConfig(
        );
      },
      onChange: (state) {
        if (state.value != '' && state.valueDisplay != '') {
          controller.contactController.text = state.valueDisplay;
        print('state: $state');
        if (state.value != '') {
          controller.contactController.text = state.value;
        }
        controller.contactId.value = int.tryParse(state.value);
  }),

My example code work well in 4.3.2 version, is there anyone has any idea that how to migrate such code to 4.3.3 version? Thanks very much!
