点击不同类型的通知，颤动重定向到不同的页面

Question

我有 2 种 Firestore 触发器来向用户发送通知 - 1 是在新用户创建请求表单时触发，2 是在用户收到另一个用户的消息时触发。对于每种情况，我想在点击通知时将用户重定向到 2 个不同的页面。 notifications 页面用于第一种情况，chatRoom 页面用于第二种情况。这是我的代码，我不知道如何根据 2 个不同的情况重定向到 2 个不同的页面。请给我一些建议。

  @override
 void initState() {
  super.initState();
 _firebaseMessaging.configure(
    onMessage: (Map<String, dynamic> message) async {

  var data = message['data'];
  if (data['screen'].toString() == 'ChatClass') {
    Navigator.push(... (context) => ChatRoom()));
  } else {
    Navigator.push(... (context) => Notifications()));
  }
}, onLaunch: (Map<String, dynamic> message) async {

  var data = message['data'];
  if (data['screen'].toString() == 'ChatClass') {
    Navigator.push(... (context) => ChatRoom()));
  } else {
    Navigator.push(... (context) => Notifications()));
  }
}, onResume: (Map<String, dynamic> message) async {
  
  var data = message['data'];
  if (data['screen'].toString() == 'ChatClass') {
    Navigator.push(... (context) => ChatRoom()));
  } else {
    Navigator.push(...(context) => Notifications()));
  }
});

}

这是我的 AndroidManifest 文件；

<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.myappName">
//
    
<application
    android:name=".Application"
    android:label="myapp"
    android:icon="@mipmap/ic_launcher">
    
    <activity
        android:name=".MainActivity"
        android:launchMode="singleTop"
        android:theme="@style/LaunchTheme"
        android:configChanges="orientation|keyboardHidden|keyboard|screenSize|smallestScreenSize|locale|layoutDirection|fontScale|screenLayout|density|uiMode"
        android:hardwareAccelerated="true"
        android:windowSoftInputMode="adjustResize">
        //
        <meta-data
          android:name="io.flutter.embedding.android.NormalTheme"
          android:resource="@style/NormalTheme"
          />
        //
        <meta-data
          android:name="io.flutter.embedding.android.SplashScreenDrawable"
          android:resource="@drawable/launch_background"
          />
        <meta-data
            android:name="com.google.firebase.messaging.default_notification_channel_id"
            android:value="high_importance_channel" />
        
        <intent-filter>
            <action android:name="android.intent.action.MAIN"/>
            <category android:name="android.intent.category.LAUNCHER"/>
        </intent-filter>
        <intent-filter>
            <action android:name="FLUTTER_NOTIFICATION_CLICK" />
            <category android:name="android.intent.category.DEFAULT" />
        </intent-filter>
    </activity>
    //
    <meta-data
        android:name="flutterEmbedding"
        android:value="2" />
</application>

Answer 1

Here is data 您需要从 Firebase 控制台发送

  notificationSecondCall() {
    firebaseMessaging.configure(
      onMessage: (Map<String, dynamic> message) async {

        // we received notification when app is in foreground 

        var data = message['data'];
        if (data['screen'].toString() == "ChatClass") {
          gotoChatRoom();  //==  your navigator method to Chat room class
        } else {
          gotoNotifications();   //==  your navigator method for Notification class
        }
      },

      onResume: (Map<String, dynamic> message) async {

        // we received notification when app is in background

        var data = message['data'];
        if (data['screen'].toString() == "ChatClass") {
          gotoChatRoom();  //==  your navigator method to Chat room class
        } else {
          gotoNotifications();   //==  your navigator method for Notification class
        }
      },

      onLaunch: (Map<String, dynamic> message) async {},
    );

    firebaseMessaging.requestNotificationPermissions(
        const IosNotificationSettings(
            sound: true, badge: true, alert: true, provisional: false));
  }

Answer 2

也许你可以创建一些枚举？

`枚举 NotificationType{

}`

您的通知将多出一个字段

class Notification{ final NotificationType type; }

你可以从你的firestore传递它并检查它吗？
