谷歌推送服务 fcm下载(国内怎么使用谷歌gcm推送)

1、在pubspec.yaml添加依赖

firebase_messaging:

flutter_local_notifications:

2.新建local_notification.dart，如下：

import 'package:firebase_core/firebase_core.dart';

import 'package:firebase_messaging/firebase_messaging.dart';

import 'package:flutter/cupertino.dart';

import 'package:flutter_local_notifications/flutter_local_notifications.dart';

import '../../../net/Api.dart';

class LocalNotification {

//静态变量_notification，存储唯一对象

static LocalNotification? _notification;

// notification的getter方法，通过LocalNotification.notification获取对象

static LocalNotification get notification => _getNotification();

//获取对象

static LocalNotification _getNotification() {

//使用私有的构造方法来创建对象

_notification ??= LocalNotification._initialize();

return _notification!;

}

FlutterLocalNotificationsPlugin np = FlutterLocalNotificationsPlugin();

// 私有的自定义命名式构造方法，通过它实现一个类;

LocalNotification._initialize() {

//初始化本地通知。设置安卓的logo，iOS不需要设置

np = FlutterLocalNotificationsPlugin();

//不能通过自定义图片设置logo

var android = const AndroidInitializationSettings('@mipmap/ic_logo');

var ios = const DarwinInitializationSettings();

np.initialize(InitializationSettings(iOS: ios, android: android));

}

void send({required String title, required String body}) async {

//在iOS13以上需要申请权限

FlutterLocalNotificationsPlugin flutterLocalNotificationsPlugin =

FlutterLocalNotificationsPlugin();

flutterLocalNotificationsPlugin.resolvePlatformSpecificImplementation<

AndroidFlutterLocalNotificationsPlugin>()?.requestPermission();

// 构建描述，暂不需要另外修改

var androidDetails = const AndroidNotificationDetails('ID', 'Name',

importance: Importance.max, priority: Priority.high);

var iosDetails = const DarwinNotificationDetails();

var details = NotificationDetails(android: androidDetails, iOS: iosDetails);

//第一个参数为通知的id，不能重复，否则通知会被替换

np.show(DateTime

.now()

.millisecondsSinceEpoch >> 10, title, body, details);

}

//添加推送相关信息

initializePushNotification() async {

WidgetsFlutterBinding.ensureInitialized();

await Firebase.initializeApp();

NotificationSettings settings =

await FirebaseMessaging.instance.requestPermission(

alert: true,

announcement: false,

badge: false,

carPlay: false,

criticalAlert: false,

provisional: false,

sound: true,

);

debugPrint('User granted permission: ${settings.authorizationStatus}');

final fcmToken = await FirebaseMessaging.instance.getToken();

if (fcmToken != null) {

//把token传给后台

// Api.showToast(msg: '推送Token:$fcmToken');

debugPrint('fcmToken ========== $fcmToken');

}

// LocalNotification.notification.send(

// title: '测试测试浿',

// body: '朝秦暮楚械');

_getPushNotificationNews();

}

//收到推送的信息

_getPushNotificationNews() {

//前台

FirebaseMessaging.onMessage.listen((RemoteMessage message) {

if (message.notification != null) {

//前台时收到通知转为本地推送

LocalNotification.notification.send(

title: '${message.notification?.title}',

body: '${message.notification?.body}');

}

});

}

}

3、在项目中代码引入推送

LocalNotification.notification.initializePushNotification();

android端配置

1、进入Google firebase 官网(https://console.firebase.google.com/)注册帐号创建项目和应用

下载生成的google-services.json文件，并将其放置在android / app中

2、在android/build.gradle文件下添加google server依赖文件 classpath 'com.google.gms:google-services:4.3.2' 如下：

3、在android/app/build.gradle文件下添加apply plugin: 'com.google.gms.google-services'和implementation 'com.google.firebase:firebase-messaging:20.2.4'，如下：

4、在AndroidManifest.xml下添加

<uses-permission android:name="android.permission.SEND_SMS" />

<uses-permission android:name="android.permission.ACCESS_NOTIFICATION_POLICY" />

<uses-permission android:name="android.permission.READ_SMS" />

如下：

5、在AndroidManifest.xml下添加

<meta-data

android:name="com.google.firebase.messaging.default_notification_icon"

android:resource="@mipmap/ic_logo" />和

<action android:name="FLUTTER_NOTIFICATION_CLICK"/>

@mipmap/ic_logo为通知和图标mipmap文件夹下

如下：

这样android端配置完成.

iOS端配置

1、生成推送证书：打开苹果开发者网站(https://developer.apple.com)。从 Member Center 进入 Certificates, Identifiers & Profiles。

对于开发环境（sandbox）的推送证书，请选择 Apple Push Notification service SSL (Sandbox)；

对于生产环境（production）的推送证书，请选择 Apple Push Notification service SSL (Production)。

2、进入Google firebase 官网（https://console.firebase.google.com/）将iOS应用添加到您的项目中，在IOS项目下云消息传递中上传证书，如下：

3、下载生成的GoogleService-Info.plist文件，打开ios /带有Xcode的Runner.xcworkspace，并在Xcode中将文件放置在ios / Runner中，如下：

4、在Xcode更新你的证书，并勾选romote notifications和Backgroid processing两个选项，如下

这样IOS端配置完成.
