Flutter IOS FCM 推送通知未进入通知栏 [英] Flutter IOS FCM push notification not coming into notification bar

问题描述

我是 Flutter 和 IOS 的新手.我正在为 Android 和 IOS 配置 FCM 推送通知.对于 android，它工作正常.我通过参考此链接完成了

这是我的颤振代码，

 class FirebaseNotifications {FirebaseMessaging _firebaseMessaging;SharedPreferences _sharedPreferences;void setUpFirebase() {_firebaseMessaging = FirebaseMessaging();initializeSharedPreferences();firebaseCloudMessaging_Listeners();}void initializeSharedPreferences() 异步 {_sharedPreferences = 等待 SharedPreferences.getInstance();}void firebaseCloudMessaging_Listeners() {if (Platform.isIOS) iOS_Permission();_firebaseMessaging.getToken().then((token) {_sharedPreferences.setString(Preferences.device_token, token);打印('令牌'+令牌);});_firebaseMessaging.configure(onMessage: (Map message) async {print('在消息 $message');},onResume: (Map message) async {print('在简历$message');},onLaunch: (Map message) async {打印('启动$消息')；},);}void iOS_Permission() {_firebaseMessaging.requestNotificationPermissions(IosNotificationSettings(声音:真，徽章:真，警报:真))；_firebaseMessaging.onIosSettingsRegistered.listen((IosNotificationSettings 设置) {print("已注册的设置:$settings");});}}

解决方案

万一其他人在未来遇到这种情况，请扩展 这个答案.问题是在 Info.plist 中 FirebaseAppDelegateProxyEnabled 被设置为 bool 而不是字符串，所以:

 FirebaseAppDelegateProxyEnabled</false>

变成

 FirebaseAppDelegateProxyEnabled<string>0</string>

I am new to Flutter and IOS. I am configuring FCM push notifications for both Android and IOS.For android its working fine.I have done by referring this link https://medium.com/@jun.chenying/flutter-tutorial-part3-push-notification-with-firebase-cloud-messaging-fcm-2fbdd84d3a5e . For IOS, if the app is opened and if I send FCM from Firebase Console at the same time , Flutter on message is called (See the screenshot , logs are there) . But if I close the app , notification is not coming to notification bar but I am receiving in Android App, I don't know where is the problem , Problem with Apple Profiles or Flutter .

IOS Build Settings and Signing & Capabilities

Here is my code in flutter,

    class FirebaseNotifications {
       FirebaseMessaging _firebaseMessaging;
       SharedPreferences _sharedPreferences;

       void setUpFirebase() {
         _firebaseMessaging = FirebaseMessaging();
         initializeSharedPreferences();
         firebaseCloudMessaging_Listeners();
        }

        void initializeSharedPreferences() async {
        _sharedPreferences = await SharedPreferences.getInstance();
        }

        void firebaseCloudMessaging_Listeners() {
        if (Platform.isIOS) iOS_Permission();
        _firebaseMessaging.getToken().then((token) {
        _sharedPreferences.setString(Preferences.device_token, token);
         print('Token'+token);
         });

         _firebaseMessaging.configure(
          onMessage: (Map<String, dynamic> message) async {
          print('on message $message');
         },
          onResume: (Map<String, dynamic> message) async {
          print('on resume $message');
         },
         onLaunch: (Map<String, dynamic> message) async {
         print('on launch $message');
         },
       );
     }

     void iOS_Permission() {
     _firebaseMessaging.requestNotificationPermissions(
     IosNotificationSettings(sound: true, badge: true, alert: true));
     _firebaseMessaging.onIosSettingsRegistered
     .listen((IosNotificationSettings settings) {
     print("Settings registered: $settings");
    });
   }
  }

解决方案

In case anyone else runs into this in the future, to expand on this answer. The issue was that in the Info.plist FirebaseAppDelegateProxyEnabled was set to bool rather than a string so:

    <key>FirebaseAppDelegateProxyEnabled</key>
    </false>

becomes

    <key>FirebaseAppDelegateProxyEnabled</key>
    <string>0</string>
