极光推送的官方网址为https://www.jiguang.cn/
注册好后进入服务中心,然后再进入开发者平台点击创建应用。 这时候会出现新页面让你填写“应用名称”和上传“应用图标”。 创建完成极光平台就会给我们两个key。
appKey : 移动客户端使用的keyMaster Secret 服务端使用的key
我们这里只做移动端不做服务端所以只需要appKey。得到这个Key也算是极光平台操作完了
2、加入dependencies依赖 github网址:https://github.com/jpush/jpush-flutter-plugin 要使用极光推送插件必须先下载包要下载包就需要先添加依赖直接把下面的代码加入pubspec.yaml文件中。
jpush_flutter: 0.0.11写完代码后选择Android Studio右上角的Packages get进行下载下载完成后进行操作。 3、build.gradle添加可以和cpu型号代码
打开android/app/src/build.gradle文件加入如下代码
defaultConfig {applicationId sscai.club.flutter_shopminSdkVersion 16targetSdkVersion 28versionCode flutterVersionCode.toInteger()versionName flutterVersionNametestInstrumentationRunner android.support.test.runner.AndroidJUnitRunner/*新加入的*/ndk {/*选择要添加的对应 cpu 类型的 .so 库。abiFilters armeabi, armeabi-v7a, x86, x86_64, mips, mips64// arm64-v8a,/*还可以添加}manifestPlaceholders [JPUSH_PKGNAME: applicationId,JPUSH_APPKEY : 这里写入你自己申请的Key哦, /*NOTE: JPush 上注册的包名对应的 Appkey.*/JPUSH_CHANNEL: developer-default, /*暂时填写默认值即可.*/]/*新加入的*/
}详细请参考https://github.com/jpush/jpush-flutter-plugin
4、主要代码编写
在 main.dart 中引入依赖
import package:flutter/material.dart;
import dart:async;import package:flutter/services.dart;
import package:jpush_flutter/jpush_flutter.dart;编写initPlatformState方法
Futurevoid initPlatformState() async {String platformVersion;try {/*监听响应方法的编写*/jpush.addEventHandler(onReceiveNotification: (MapString, dynamic message) async {print(flutter 接收到推送: $message);setState(() {debugLable 接收到推送: $message;});});} on PlatformException {platformVersion 平台版本获取失败请检查;}if (!mounted){return;}setState(() {debugLable platformVersion;});
}编写build的视图
overrideWidget build(BuildContext context) {return new MaterialApp(home: new Scaffold(appBar: new AppBar(title: const Text(极光推送),),body: new Center(child: new Column(children:[new Text(结果: $debugLable\n),new RaisedButton(child: new Text(点击发送推送消息\n,),onPressed: () {/*三秒后出发本地推送*/var fireDate DateTime.fromMillisecondsSinceEpoch(DateTime.now().millisecondsSinceEpoch 3000);var localNotification LocalNotification(id: 234,title: 我是推送测试标题,buildId: 1,content: 看到了说明已经成功了,fireTime: fireDate,subtitle: 一个测试,);jpush.sendLocalNotification(localNotification).then((res) {setState(() {debugLable res;});});}),])),),);}main.dart 完整代码
import package:flutter/material.dart;
import dart:async;import package:flutter/services.dart;
import package:jpush_flutter/jpush_flutter.dart;void main() runApp(new MyApp());class MyApp extends StatefulWidget {override_MyAppState createState() new _MyAppState();
}class _MyAppState extends StateMyApp {String debugLable Unknown; /*错误信息*/final JPush jpush new JPush(); /* 初始化极光插件*/overridevoid initState() {super.initState();initPlatformState(); /*极光插件平台初始化*/}Futurevoid initPlatformState() async {String platformVersion;try {/*监听响应方法的编写*/jpush.addEventHandler(onReceiveNotification: (MapString, dynamic message) async {print(flutter 接收到推送: $message);setState(() {debugLable 接收到推送: $message;});});} on PlatformException {platformVersion 平台版本获取失败请检查;}if (!mounted){return;}setState(() {debugLable platformVersion;});}/*编写视图*/overrideWidget build(BuildContext context) {return new MaterialApp(home: new Scaffold(appBar: new AppBar(title: const Text(极光推送),),body: new Center(child: new Column(children:[new Text(结果: $debugLable\n),new RaisedButton(child: new Text(点击发送推送消息\n,),onPressed: () {/*三秒后出发本地推送*/var fireDate DateTime.fromMillisecondsSinceEpoch(DateTime.now().millisecondsSinceEpoch 3000);var localNotification LocalNotification(id: 234,title: 我是推送测试标题,buildId: 1,content: 看到了说明已经成功了,fireTime: fireDate,subtitle: 一个测试,);jpush.sendLocalNotification(localNotification).then((res) {setState(() {debugLable res;});});}),])),),);}
}效果图 4、扩展几个方法
收到推送提醒
监听addReceiveNotificationListener方法
/*
* 收到推送提醒
* */void _ReceiveNotification() async {FlutterJPush.addReceiveNotificationListener((JPushNotification notification) {setState(() {/// 收到推送print(收到推送提醒: $notification);});});}打开推送提醒
监听 addReceiveNotificationListener方法 /** 打开推送提醒* */void _OpenNotification() async {FlutterJPush.addReceiveOpenNotificationListener((JPushNotification notification) {setState(() {print(打开了推送提醒: $notification);});});}监听接收自定义消息
一般项目这个方法会用的比较多吧
监听 addReceiveCustomMsgListener方法 /** 监听接收自定义消息* */void _ReceiveCustomMsg() async {FlutterJPush.addReceiveCustomMsgListener((JPushMessage msg) {setState(() {print(收到推送消息提醒: $msg);});});}
