android - flutter_local_notifications 分组通知不起作用

Question

我是 flutter 的新手我已经厌倦了对来自 Firebase Push Notification 的通知进行分组.我正在使用 flutter_local_notification用于在通知栏中显示通知的插件。

我为每个通知获得不同的标签。所以我使用了这个插件的分组功能来分组通知。

但它似乎仍然无法正常工作，它在通知栏中收到多个通知。任何帮助，将不胜感激。正如他们的文件所说，我在 24 级以上的 api 级别上尝试了这个。

我试过的示例代码如下。

String groupKey = 'com.android.example.WORK_EMAIL';

String groupChannelId = 'grouped channel id';

String groupChannelName = 'grouped channel name';

String groupChannelDescription = 'grouped channel description';

AndroidNotificationDetails firstNotificationAndroidSpecifics =
    new AndroidNotificationDetails(
        groupChannelId, groupChannelName, groupChannelDescription,
        importance: Importance.Max,
        priority: Priority.High,
        groupKey: groupKey);

NotificationDetails firstNotificationPlatformSpecifics =
    new NotificationDetails(firstNotificationAndroidSpecifics, null);

await flutterLocalNotificationsPlugin.show(1, 'Alex Faarborg',
    'You will not believe...', firstNotificationPlatformSpecifics);

AndroidNotificationDetails secondNotificationAndroidSpecifics =
    new AndroidNotificationDetails(
        groupChannelId, groupChannelName, groupChannelDescription,
        importance: Importance.Max,
        priority: Priority.High,
        groupKey: groupKey);

NotificationDetails secondNotificationPlatformSpecifics =
    new NotificationDetails(secondNotificationAndroidSpecifics, null);

await flutterLocalNotificationsPlugin.show(
    2,
    'Jeff Chang',
    'Please join us to celebrate the...',
    secondNotificationPlatformSpecifics);

经过大量修补，下面的解决方案对我有用。您只需要setAsGroupSummary: true只到第一次通知。我的 AndroidNotificationDetails 的实现如下(我使用BigTextStyleInformation顺便说一句):

AndroidNotificationDetails _androidDetails(_NotificationType type, bool isGroupContainer) =>
      AndroidNotificationDetails(
          _NotificationPreference.GROUP_CHANNEL_ID,
          _NotificationPreference.GROUP_CHANNEL_NAME,
          _NotificationPreference.GROUP_CHANNEL_DESCRIPTION,
          groupKey: _NotificationPreference.GROUP_CHANNEL,
          icon: _NotificationPreference.APP_ICON,
          priority: Priority.high,
          importance: Importance.max,
          setAsGroupSummary: isGroupContainer,
          styleInformation: BigTextStyleInformation(type.getDetails.body,
              contentTitle: type.getDetails.title));

NotificationDetails _flutterNotificationDetails(_NotificationType type, bool isGroupContainer) =>
      NotificationDetails(android: _androidDetails(type, isGroupContainer), iOS: _iosDetails);

所以要在一个组中显示多个通知:

  @override
  Future<void> showNotification() async {
    await plugin.show(0, '', '',
        _flutterNotificationDetails(_NotificationType.Container,true), payload: '1');
    await plugin.show(_NotificationType.Type1.getDetails.id, _NotificationType.Type1.getDetails.title, _NotificationType.Type1.getDetails.body,
        _flutterNotificationDetails(_NotificationType.Type1,false));
    await plugin.show(_NotificationType.Type2.getDetails.id, _NotificationType.Type2.getDetails.title, _NotificationType.Type2.getDetails.body,
        _flutterNotificationDetails(_NotificationType.Type2,false));
  }

这将显示一个包含 2 个 child 的组通知。
