获取导航无法正常运行

我尝试使用声音空的安全性构建扑动项目，并且使用了： ^4.6.1。以前，在没有启用无效安全性的情况下，使用GET的导航工作正常，但是现在，导航无法正常运行。最初，我有错误 抛出了另一个例外：'软件包/flutter/src/widgets/navigator.dart'：失败断言：第4028 line 4028 pos 12：'！_debuglocked'：是不正确的。 通过使用AddPostFrameCallback解决。但是，每当我尝试通过点击“查看全部”来导航到新屏幕时，打印语句就会执行，但是除非我在屏幕上的其他地方点击或拖动其他地方，否则它不会导航到新屏幕。

GestureDetector(
                    onTap: () {
                      print("tapped");
                      WidgetsBinding.instance.addPostFrameCallback(
                          (_) => Get.toNamed(AllProductsScreen.route));
                    },
                    child: const Text(
                      "See All",
                      style: kHeaderTextStyle,
                    ),
                  )

I tried building flutter project with sound null safety and I am using get: ^4.6.1. Previously, without enabling null safety, navigation using Get was working fine, but now, navigation is not functioning properly. Initially, I got error
Another exception was thrown: 'package:flutter/src/widgets/navigator.dart': Failed assertion: line 4028 pos 12: '!_debugLocked': is not true.
which was resolved by using addPostFrameCallback. However, Whenever I try to navigate to new screen by tapping "See All", print statement gets executed, but it won't navigate to new screen unless I tap or drag somewhere else in screen.

GestureDetector(
                    onTap: () {
                      print("tapped");
                      WidgetsBinding.instance.addPostFrameCallback(
                          (_) => Get.toNamed(AllProductsScreen.route));
                    },
                    child: const Text(
                      "See All",
                      style: kHeaderTextStyle,
                    ),
                  )
