当应用在前景时,我会收到通知,而不是在后台应用程序时收到通知。另外,我有2个小时或更长时间的Google-ed/stackoverflow-ed,但能够解决这个问题。

My Configurations are :

  firebase_auth: ^0.10.0
firebase_messaging: ^5.0.0

The manifest is like this:

Manifest

The code is like this:

final notifications = new FirebaseMessaging();

class AppNotifications {
static String fcmToken = '';

static Future<Null> init() async {
appLogs("AppNotifications init");

notifications.requestNotificationPermissions(const IosNotificationSettings(sound: true, badge: true, alert: true));

await configure();

fcmToken = await notifications.getToken();
appLogs("FCM TOKEN : " + fcmToken);

notifications.onTokenRefresh.listen((newToken) {
fcmToken = newToken;
appLogs("FCM TOKEN onTokenRefresh: " + fcmToken);
});

await updateFCMToken();
}

static Future<Null> configure() async {
appLogs("AppNotifications Configure");

notifications.configure(onMessage: (msg) {
appLogs('FCM onMessage: ' + msg.toString());
}, onLaunch: (lun) {
appLogs('FCM onLaunch: ' + lun.toString());
}, onResume: (res) {
appLogs('FCM onResume: ' + res.toString());
});
}

static Future<Null> updateFCMToken() async {
auth.currentUser.fcmToken = fcmToken;
await updateUserInSharedPreference();
}
}

I am calling the function like this:

class HomeScreenState extends State<HomeScreen> {


@override
void initState() {
super.initState();

Future.delayed(Duration(milliseconds: 100), () async {
await AppNotifications.init();
});
}

..... ....

I am using postman for sending the notification :

Postman

My logs :

**(App is Foreground)**  I/flutter (31888): APPLOGS : FCM onMessage: {notification: {title: Test notification title, body: Test notification body}, data: {status: done, id: 1, foo: bar, click_action: FLUTTER_NOTIFICATION_CLICK}}
**(App is Background)** W/FirebaseMessaging(31888): Missing Default Notification Channel metadata in AndroidManifest. Default value will be used.

最佳答案

lost my 2 days to fix this issue, it may helpful for you.notification tag only for showing notification. you can access only data content on onResume/onLaunch.

If you want handle notification message inside onResume/onLaunch add those messages in data tag also, Then you can do what ever you want.

refer more detail on this link

发送此通知消息

{
"notification": {
"body": "body",
"title": "title"
},
"priority": "high",
"data": {
"body": "body",
"title": "title"
"click_action": "FLUTTER_NOTIFICATION_CLICK",
"id": "1",
"status": "done",
"image": "https://ibin.co/2t1lLdpfS06F.png",
},
"to": <your token>
}

you will receive below information onResume or onLaunch, your notification tag will be empty here

{notification: {}, data: {image: https://ibin.co/2t1lLdpfS06F.png, google.original_priority: high, google.sent_time: 1560858283888, google.delivered_priority: high, body: body , title: title, click_action: FLUTTER_NOTIFICATION_CLICK, google.message_id: 0:1560858283908500%eefdc741eefdc741, collapse_key: <package>, google.ttl: 2419200, from: <from>, id: 1, status: done}}

you can use title and body which is added in data tag.
