在子类中更改子类 PartnerInviter 的类成员时，它也会以某种方式更改父类的状态，即 PartnerConnect 。 isInviteOption：true，isInviteSent：false =>父窗口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,
),
);
}
}
子窗口小部件是：
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();
}
