How do I use Get.toNamed('/nextpage'); in conjunction with animations for OpenContainer use?

[BrotherPeng]

OpenContainer(
openBuilder: (context, closedContainer) {
return MyPage(); _// _
},
openColor: Theme.of(context).cardColor,
onClosed: (success) {},
closedShape: const RoundedRectangleBorder(
borderRadius: BorderRadius.all(Radius.circular(4)),
),
closedColor: Theme.of(context).colorScheme.primary,
closedElevation: 2,
closedBuilder: (context, openContainer) {
return InkWell(

                      onTap: () {
                        openContainer();
                         // Get.toNamed('nextpage?a=1&b=2');
                      },

GetPage(
name: _Paths.MYPAGE,
page: () => const MyPage(),
binding: MyPageBinding(),
),

OpenContainer in openBuilder returned MyPage, openContainer(); open this page, I need to use Get to manage page routing jumps as well as url parameters, please help me, bind get
