如何在点击推送通知时打开特定屏幕 [英] how to open particular screen on clicking on push notification for flutter

问题描述

我正在尝试在单击推送通知时实现打开特定屏幕，而我的有效负载如下所示:

I am trying to achieve open specific screen on clicking push notification and my payload looks like this:

 var payload = {
        notification: {
            title: notificationTitle,
            body: notificationMessage,
            click_action:"/screena",sound:"default",
        }
    };

我收到通知，但无法捕捉通知点击事件，如何扑捉它.我正在使用动态消息传递

I am getting notification but I am unable to catch notification click event in flutter how to catch it. I am using flutter messaging

https://github.com/flutter/plugins/tree/master/包/firebase_messaging

我的Firebase推送消息服务代码如下:

and my firebase push message service code looks like this

 pushMessagingService() async{
messagingreference.configure(
onMessage: (Map<String, dynamic> message) {

  print("I am here in on message");
  print(message);
},
onLaunch: (Map<String, dynamic> message) {
  print("I am here onLaunch");
  print(message);
},
onResume: (Map<String, dynamic> message) {
  print("I am hereonResume");
  print(message);
},
);
  messagingreference.requestNotificationPermissions(
  const IosNotificationSettings(sound: true, badge: true, alert: true));
 messagingreference.onIosSettingsRegistered
  .listen((IosNotificationSettings settings) {
print("Settings registered: $settings");
 });
 messagingreference.getToken().then((String token) async {


print(token);
 });
 }

在这里，当我的应用程序在前台时，我可以收到@xqwzts在消息中说的消息，但我的问题是如何从系统托盘中引发的推送通知中捕获点击事件并导航到所需的屏幕.

here I can get the message as @xqwzts said in on message when my app is in the foreground but my question is how to catch click event from push notification raised in the system tray and navigate to the required screen.

推荐答案

这里有几件事:

1- click_action必须设置为"FLUTTER_NOTIFICATION_CLICK"

2- click_action必须在有效载荷的data部分中设置

2- click_action has to be set in the data section of a payload

DATA='{
  "notification": {
    "body": "this is a body",
    "title": "this is a title"
    "click_action": "FLUTTER_NOTIFICATION_CLICK",
  },
  "data": {
    "sound": "default", 
    "status": "done",
    "screen": "screenA",
  },
  "to": "<FCM TOKEN>"
}'

这应该可以让您在flutter应用程序的onMessage处理程序中接收消息.

This should allow you to receive the message in the onMessage handler in your flutter app.

您可以从那里致电Navigator.of(context).pushNamed(message['screen']).

如果此时没有BuildContext，则可以将GlobalKey注册为MaterialApp的navigatorKey属性，并使用它通过Navigator >

If you don't have a BuildContext at that point, you can register a GlobalKey as the navigatorKey property of your MaterialApp, and use it to access your Navigator globally, via GlobalKey.currentState
