对于在更新到 iOS14 后因 FCM 而疯狂的每个人Xcode12.我花了 2 天时间解决了这些问题.在模拟器上，它可以工作，但在真实设备上，它不会.也许这些说明可以帮助某人&防止浪费时间.另外，如果所有这些步骤都可以改进，那么听听 Flutter Guru 的一些想法会很棒:).

如果可以的话，你可以试试 sample payload.
声明 这里
让有效载荷 = {通知: {标题:'匹配'，body: `${user2name} 匹配你`,},数据: {键:'匹配'，id:用户2，正文:用户名，click_action:FLUTTER_NOTIFICATION_CLICK"；},安卓: {优先级:高"，},apns:{有效载荷:{应用:{内容可用:真，},},标题:{apns-push-type":背景"，"apns-priority": "5",//当 `contentAvailable` 设置为 true 时，必须为 `5`."apns-topic": "io.flutter.plugins.firebase.messaging",//包标识符},},令牌:deviceTokenuUser1.data()['tokens'],};For everyone who goes crazy from FCM after updating to iOS14 & Xcode12. I spent 2 days resolving the issues. On the simulator, it works but on a real device, it does not. Maybe these instructions can help someone & prevent wasting the time. Also, it would be great to listen to some thoughts from Flutter Guru if all these steps can be improved :).
Notice: Instructions for new FCM versions 9+

Your message must be sent with these options:
{
mutableContent: true,
contentAvailable: true,
apnsPushType: "background"
}
Just an example to use in callable function
exports.sendNotification = functions.https.onCall(
async (data) => {
console.log(data, "this sendNotification data");
var userTokens = [USERTOKEN1,USERTOKEN2,USERTOKEN3];
var payload = {
notification: {
title: '',
body: '',
image: '',
},
data: {
type:'',
},
};
for (const [userToken,userUID] of Object.entries(userTokens)) {
admin.messaging().sendToDevice(userToken, payload, {
mutableContent: true,
contentAvailable: true,
apnsPushType: "background"
});
}
return {code: 100, message: "notifications send successfully"};
});

void initialise() {

var ios = IOSInitializationSettings();
var platform = InitializationSettings(android, ios);
_flutterLocalNotificationsPlugin.initialize(platform);
_firebaseMessaging.configure(

_app.storeNotification(message);
},
onResume: (Map<String, dynamic> message) async {
_app.storeNotification(message);
},
onMessage: (Map<String, dynamic> message) async {
_app.storeNotification(message);
if (_prefs.get('pushServiceState') == true) _showNotification(message);
},
onBackgroundMessage: Platform.isIOS ? null : backgroundMessageHandler,
);
if (Platform.isIOS) iOSPermission();
_firebaseMessaging.getToken().then((token) {
_prefs.put('fcmToken', token);
});
}
void iOSPermission() {
_firebaseMessaging.requestNotificationPermissions(
IosNotificationSettings(sound: true, badge: true, alert: true, provisional: true));
_firebaseMessaging.onIosSettingsRegistered.listen((IosNotificationSettings settings) {
print('IOS Setting Registed');
});
}
Future<void> _showNotification(Map<String, dynamic> message) async {
var android = AndroidNotificationDetails(
'messages',
"Octopoos",
"channelDescription",
);
var iOS = IOSNotificationDetails();
await _flutterLocalNotificationsPlugin.show(
0,
message['notification']['title'],
message['notification']['body'],
NotificationDetails(android, iOS),
);
}
}
final FirebaseMessagingService _fcm = FirebaseMessagingService();
@override
void afterFirstLayout(BuildContext context) {
_fcm.initialise();
}
Only after all these steps, my FCM work correctly.
can u try sample payload if it works.
it is stated here
let payload = {
notification: {
title: 'Match',
body: `${user2name} Match with You`,
},
data: {
key: 'Match',
id: user2,
body: user2name,
click_action: "FLUTTER_NOTIFICATION_CLICK"
},
android: {
priority: "high",
},
apns: {
payload: {
aps: {
contentAvailable: true,
},
},
headers: {
"apns-push-type": "background",
"apns-priority": "5", // Must be `5` when `contentAvailable` is set to true.
"apns-topic": "io.flutter.plugins.firebase.messaging", // bundle identifier
},
},
token: deviceTokenuUser1.data()['tokens'],
};
