Flutter 子部件刷新父部件 - 如何不这样做

Question

When the class members of child class PartnerInviter are changed inside the child class, somehow it changes the state of the parent class as well which is PartnerConnect . isInviteOption: true, isInviteSent: false => 父小部件将标志重置为 false、false。 我正在调用 PartnerConnect 的构建。 我该如何解决？

父小部件是：

class PartnerConnect extends StatefulWidget{

  bool isInviter = true;

  @override
  State<StatefulWidget> createState() {
    return PartnerConnectState();
  }
}

class PartnerConnectState extends State<PartnerConnect>{

  final _scaffoldKey = GlobalKey<ScaffoldState>();
  double card_elevation = 1;
  TextEditingController phoneNumber = TextEditingController();

  @override
  Widget build(BuildContext context) {

    return SafeArea(
      child: Scaffold(
        key: _scaffoldKey,
        body: widget.isInviter ? PartnerInviter(
          isInviteOption: false,
          isInviteSent: false,
          scaffoldKey: _scaffoldKey,
        ) : PartnerInvitee(
            isInvitationAccepted: true,
            inviterNumber: '9********0',
            scaffoldKey: _scaffoldKey),
        appBar: AppBar(
          title: Text('Partner Connect'),
          backgroundColor: Colors.white,
          elevation: 0.0,
        ),
        backgroundColor: Colors.white,
      ),
    );
  }

}

子小部件是：

class PartnerInviter extends StatefulWidget{

  bool isInviteOption = false;
  bool isInviteSent = false;
  GlobalKey<ScaffoldState> scaffoldKey;

  PartnerInviter({this.isInviteOption, this.isInviteSent, this.scaffoldKey});

  @override
  State<StatefulWidget> createState() {
    return _PartnerInviterState();
  }
}

class _PartnerInviterState extends State<PartnerInviter> {

  double card_elevation = 1;
  TextEditingController phoneNumber = TextEditingController();

  @override
  Widget build(BuildContext context) {
    return inviterConnectBody();
  }

  Widget inviterConnectBody(){
    return Container(
      margin: EdgeInsets.all(MediaQuery.of(context).size.width*0.1),
      child: ListView(
        children: <Widget>[
          Visibility(
            child: numberInputWidget(),
            visible: widget.isInviteOption,
            replacement: Container(

                replacement: Container(
                  child: RequestRevokeWidget(phoneNum: phoneNumber.value.text),
                ),
              ),
            ),
          )
        ],
      ),
    );
  }
