Question

按照https://pub.dev/packages/firebase_messaging上的说明，我已经实施了FCM。尽管我设置了click_action: FLUTTER_NOTIFICATION_CLICK，但是当我单击通知托盘项时，它不会打开该应用程序。颤动应用程序从云功能接收的数据如下。至少如何在单击通知后打开应用程序？

onMessage: {notification: {title: pi, body: text message.}, 
          data: {USER_NAME: pi, click_action: FLUTTER_NOTIFICATION_CLICK, }}

云功能有效载荷

 const payload = {
        notification: {
            title: sender,
            body: content,
            clickAction: 'ChatActivity',
        },
        data: {
            "click_action": 'FLUTTER_NOTIFICATION_CLICK',
            "USER_NAME": sender,
        }
    };

我还创建了通知通道，并且AndroidManifest已正确配置。

private void createNotificationChannel() {
        // Create the NotificationChannel, but only on API 26+ because
        // the NotificationChannel class is new and not in the support library
        if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {
            CharSequence name = getString(R.string.app_name);
            String description = getString(R.string.notification_channel_description);
            int importance = NotificationManager.IMPORTANCE_HIGH;
            NotificationChannel channel = new NotificationChannel(getString(R.string.default_notification_channel_id), name, importance);
            channel.setDescription(description);
            // Register the channel with the system; you can't change the importance
            // or other notification behaviors after this
            NotificationManager notificationManager = getSystemService(NotificationManager.class);
            notificationManager.createNotificationChannel(channel);
        }
    }

我已将click操作放入通知json，它对我有用。

notification: {
  title: sender,
  body: content,
  click_action: 'FLUTTER_NOTIFICATION_CLICK'
}

只有onResume和onLaunch回调才需要click操作，因此请确保按照pub.dev文档中的说明实施该操作：

 _firebaseMessaging.configure(
       onMessage: (Map<String, dynamic> message) async {
         print("onMessage: $message");
         _showItemDialog(message);
       },
       onBackgroundMessage: myBackgroundMessageHandler,
       onLaunch: (Map<String, dynamic> message) async {
         print("onLaunch: $message");
         _navigateToItemDetail(message);
       },
       onResume: (Map<String, dynamic> message) async {
         print("onResume: $message");
         _navigateToItemDetail(message);
       },
     );

点击通知后，Android上的Flutter应用无法打开应用
