在GetX状态管理的帮助下，我已将Firebase云消息集成到我的Flutter移动应用程序中。此外，我使用Laravel和Firebase Admin SDK向我的应用程序发送通知。
前台状态和后台状态(已暂停(的通知都正常工作。当我点击应用程序处于终止状态(应用程序关闭(的通知时，问题就开始了。我必须在防溅屏和主页之间设置一个延迟吗？
我试过这样做，但错误仍然发生
//open notif content from terminated state of the app
FirebaseMessaging.instance.getInitialMessage().then((message) {
if (message != null) {
print('TERMINATED');
if (FirebaseAuth.instance.currentUser != null) {
final redirectRoute = message.data['route'];
if (redirectRoute != null) {
//adding delay here since my splashscreen have the same delay
Future.delayed(const Duration(seconds: 6));
bottomnavbarController.updateIndex(int.parse(redirectRoute));
}
} else {
Get.offAllNamed(Routes.LOGIN);
}
}
});
我收到这个错误
Unhandled Exception:
You are trying to use contextless
navigation without a GetMaterialApp or Get.key
这是我的主要艺术
//open notif content from terminated state of the app
FirebaseMessaging.instance.getInitialMessage().then((message) {
if (message != null) {
if (FirebaseAuth.instance.currentUser == null) {
Get.offAllNamed(Routes.LOGIN);
} else {
final redirectRoute = message.data['route'];
if (redirectRoute != null) {
print('TERMINATED');
bottomnavbarController.updateIndex(int.parse(redirectRoute));
}
}
}
});
@override

这是我的底部导航控制器

void updateIndex(int index){
bottomNavIndex.value = index;
Get.offAllNamed(Routes.PAGEWRAPPER);
}
}

我现在已经用另一种解决方案解决了这个问题。这是主要的艺术
@override
void initState() {
super.initState();
//open notif content from terminated state of the app
FirebaseMessaging.instance.getInitialMessage().then((message) {
if (message != null) {
print('TERMINATED');
final redirectRoute = message.data['route'];
print('redirectRoute $redirectRoute');
bottomnavbarController.updateIndex(int.parse(redirectRoute));
//remove redirect route here, so the unknownRoute will trigger the default route
}
});
//only works if app in foreground
FirebaseMessaging.onMessage.listen((message) {
LocalNotificationService.display(message);
});
//onclick notif system tray only works if app in background but not termi
FirebaseMessaging.onMessageOpenedApp.listen((message) {
final redirectRoute = message.data['route'];
if (redirectRoute != null) {
print('BACKGROUND');
print('redirectRoute $redirectRoute');
bottomnavbarController.updateIndex(int.parse(redirectRoute));
Get.offAllNamed(Routes.PAGEWRAPPER);
}
});
}
@override
Widget build(BuildContext context) {
final authController = Get.put(AuthController(), permanent: true);
return FutureBuilder(
future: Future.delayed(const Duration(seconds: 6)),
builder: (context, snapshot) {
if (snapshot.connectionState == ConnectionState.done) {
return Obx(
() => GetMaterialApp(
debugShowCheckedModeBanner: false,
title: "Application",
theme: ThemeData(
appBarTheme: const AppBarTheme(
elevation: 0.2,
foregroundColor: Colors.black,
backgroundColor: Colors.white),
),
initialRoute: authController.isSkipIntro.isTrue
? authController.isAuthAndVerified.isTrue
? Routes.PAGEWRAPPER
: Routes.LOGIN
: Routes.INTRODUCTION,
getPages: AppPages.routes,
unknownRoute: authController.isAuthAndVerified.isTrue ? AppPages.routes[11] : AppPages.routes[1],
),
);
}
return FutureBuilder(
future: authController.firstInitialize(),
builder: (context, snapshot) {
return const SplashScreen();
},
);
},
);
}
如果路由为null，我在GetMaterialApp上添加了这个unknownRoute:，因为getInitialMessage()中的路由返回null，所以它将一个数组传递到AppPages类内登录页面的页面包装器索引。
我已经使用Get.key进行了定义，但仍然返回null。也许app_routes.dart在GetMaterialApp之前还没有创建。也许这就是它返回null的原因。
我仍然不知道为什么会发生这种事。也许这是GetX插件的一个错误。不管怎样，这仍然适用于我，因为我已经更新了底部导航索引。
