屏幕和它下面有控制器当我导航第一次页面加载，但当我导航第二次它不像第一次重新加载我面临这个问题，因为要从API请求数据每次我打开页面控制器是下面的屏幕代码苏任何想法

Widget build(BuildContext context) {
    Get.put(MainpageConrolloerImp());
    return GetBuilder<MainpageConrolloerImp>(
        builder: (controller) => Scaffold(
            drawer: NavigationDrawer(
              name: thecontrol.thename,
            ),
            body: controller.pageslist.elementAt(controller.currentpage),
            bottomNavigationBar: Container(
                decoration: BoxDecoration(
                  borderRadius: const BorderRadius.only(
                      topLeft: Radius.circular(16),
                      topRight: Radius.circular(16)),
                  color: Colors.white,
                  boxShadow: [
                    BoxShadow(
                      blurRadius: 20,
                      color: Colors.black.withOpacity(.1),
                    )
                  ],
                ),
                child: SafeArea(

                    padding: const EdgeInsets.symmetric(
                        horizontal: 4.0, vertical: 16),
                    child: GNav(

                      tabBackgroundColor:

你可以让你的主页和其他页面变成StatefulWidget。提供initState方法-〉每次在页面之间导航时，它都会再次调用initState

class HomePage extends StatefulWidget {
  const HomePage({super.key});

  @override
  State<HomePage> createState() => _HomePageState();
}

class _HomePageState extends State<HomePage> {
  @override
  Widget build(BuildContext context) {
    return Container();
  }

  @override
  void initState() {
    super.initState();
    print("init home page");
  }
}

class CartPage extends StatefulWidget {
  const CartPage({super.key});

  @override
  State<CartPage> createState() => _CartPageState();
}

class _CartPageState extends State<CartPage> {
  @override
  void initState() {
    super.initState();
    print("init cart page");
  }

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

如果你坚持使用无状态-〉请提供Gnav包的onTabChanged函数

onTabChange: (index) {
            if (index == 1) {
             // Do Cart's work  
            }
            else if (index ==0) {
             //do home's work
            }
},
