如何从 FCM 获取全屏通知？
How to get a full screen notification from FCM?
我正在构建一个家庭自动化项目，它有一个火灾传感器，如果检测到火灾，它将写入 Firebase 数据库，然后我需要为用户发出警报。
我设法触发了来自 Firebase 云功能的通知，但这并不是我想要的。
我想要的是使用自定义声音向用户发出全屏通知，例如 phone 警报或发生火警时的应用程序调用 - 数据库中发生变化 -
我在 运行 我的应用程序：
时尝试作为顶级函数没有错误
firebaseMessaging.configure(
onMessage: (Map<String, dynamic> message) async {
print('onMessage: $message');
toast3('asdasdsawwwww $message');
setMessage(message);
},
onLaunch: (Map<String, dynamic> message) async {
print('onLaunch: $message');
setMessage(message);
},
onResume: (Map<String, dynamic> message) async {
print('onResume: $message');
setMessage(message);
},
onBackgroundMessage: myBackgroundMessageHandler);
print('onMessage:12qew11');
firebaseMessaging.requestNotificationPermissions(
const IosNotificationSettings(sound: true, badge: true, alert: true),
);
}
Future<dynamic> myBackgroundMessageHandler(Map<String, dynamic> message) {
print('HEREE');
final assetsAudioPlayer = AssetsAudioPlayer();
assetsAudioPlayer.open(
Audio("assets/audio/alarm.mp3"),
);
return Fluttertoast.showToast(
msg: 'done background:))))$message',
toastLength: Toast.LENGTH_LONG,
gravity: ToastGravity.BOTTOM,
timeInSecForIos: 4,
backgroundColor: Colors.redAccent,
textColor: Colors.white,
fontSize: 15.0);
}
我的 Firebase 函数：
const functions = require('firebase-functions');
const admin = require('firebase-admin');
admin.initializeApp(functions.config().functions);
var fireDatabase;
exports.myFirstCloudFun = functions.database.ref('/usersData/{userID}/Fire').onUpdate(async (event, context) => {
const uidGotten = context.params.userID;
const fireData = event.after.val()
console.log('data changed in fire is' + fireData + 'userID is ' + uidGotten);
const usereIdTokens = await admin
.firestore()
.collection(uidGotten)
.doc('userTokens')
.get();
console.log('Tokens to try are' + usereIdTokens.data);
var tokens = usereIdTokens.data().user_all_tokens;
var payload = {
notification: {
title: 'Push Title',
body: 'Push Body' + fireData,
sound: 'default',
},
data: {
push_key: 'Fire Value Is',
key1: "fireData is " + fireData,
},
};
tokens.forEach.toString().trim;
console.log('Tokens to send are ' + tokens[1] + ' ////// ' + tokens);
try {
const response = await admin.messaging().sendToDevice(tokens, payload);
console.log('Notification sent successfully');
} catch (err) {
console.log(err);
}
});

但是后台没有打开应用我什么也没有，为什么没有调用onBackgroundMessage函数？
我的问题是我怎样才能实现什么是应用程序调用或类似的东西？
或 是否有更好的方法来执行此操作，是否有其他方法可以通过更改 firebase 数据库在我的项目中实现该火警功能？

我有一些方法可以解决这个问题。
解决方案 1：
您要做的第一件事是检查 iOS 是否支持 onBackgroundMessage。
而在Android中，你必须开启Allow running in background选项。
解决方案 2：
通过 flutter_local_notifications 包创建一个高重要性频道。
flutter_local_notifications 包裹 link: https://pub.dev/packages/flutter_local_notifications
解决方案 3：
- 在文件夹 java/com/yourdomain
中创建一个新文件 App.java
package com.yourdomain;
import io.flutter.app.FlutterApplication;
public class App extends FlutterApplication {
@Override
public void onCreate() {
super.onCreate();
}
}
- 然后，在
AndroidManifest.xml 文件中，添加 android:name=".App"
<application
android:name=".App"
...
>
之后重建应用程序，即使应用程序被终止或终止，通知也会正常工作。
在 Android，要在应用程序处于后台时调用您的 onBackgroundMessage，FCM 消息必须是没有通知的数据消息，请查看此处：https://firebase.google.com/docs/cloud-messaging/android/receive
此外，当设备处于休眠状态时，要立即接收消息，您应该禁用电池优化，看这个：https://developer.android.com/training/monitoring-device-state/doze-standby
好的。
自更新后8.0.0-dev.1
我们可以默认获取onBackgroundMessage，不需要这些安装过程
NEW: FirebaseMessaging.onBackgroundMessage() Sets a background message
handler to trigger when the app is in the background or terminated.
