我正在努力实现这样的目标
我正在使用 flutter_local_notifications: ^4.0.1+2 。这是我目前所做的
BigTextStyleInformation bigTextStyleInformation =
BigTextStyleInformation(
payload.notification.body,
htmlFormatBigText: true,
contentTitle: payload.notification.title,
htmlFormatContentTitle: true,
summaryText: payload.data['group_name'].toString(),
htmlFormatSummaryText: true,
);
AndroidNotificationDetails androidPlatformChannelSpecifics =
AndroidNotificationDetails(
payload.data['group_name'].toString(),
payload.data['group_name'].toString(),
payload.data['group_name'].toString(),
styleInformation: bigTextStyleInformation,
groupKey: payload.data['group_id'].toString(),
setAsGroupSummary: true,
importance: Importance.high,
);
//
NotificationDetails platformChannelSpecifics =
NotificationDetails(android: androidPlatformChannelSpecifics);
await flutterLocalNotificationsPlugin.show(
int.parse(payload.data['chat_index']),
payload.notification.title,
payload.notification.body,
platformChannelSpecifics);
这是我发送到 fcm 服务器的内容
{
"registration_ids": [
"dhFLSBuAT3yYC4XoeY7oKf:APA91bGbtYTxmHhua7kewUbR1-PCHlGXyS_WP1jP-vjoLkJ_JoB69fuR8XO8hfmv-_r8VekBIkuFqhhJaHSnlKIJVRaeCAE7Mu682ffZ4MASC2O_v0QR--pQOqY3Anm7Q8liEh4Sg6f9"
],
"notification": {
"body": "Example Message",
"title": "GROUP TEST 1",
"icon": "@drawable/ic_stat_notification_logo",
"sound": "mySound",
"priority": "high",
"show_in_foreground": true,
"click_action": "FLUTTER_NOTIFICATION_CLICK"
},
"data": {
"type": "chat",
"openScreen": true,
"useHomeScreen": true,
"homeScreenBottomIndex": 1,
"group_id": 1,
"group_name": "GROUP 1",
"chat_index": 1
}
}
从我上面的脚本我得到这个结果
有什么解决办法吗?

退房awesome_notifications:0.0.6+9
使用 Group Key
,您可以确定用于以紧凑形式对通知进行分组的通用键。
您甚至可以使用 Group Sort
来确定分组内的通知排序顺序
您可以查看 Grouping-Notifications 条本地通知。
以下代码是 https://developer.android.com/training/notify-user/group.html
提供的示例的“转换为 flutter”代码 -
const String groupKey = 'com.android.example.WORK_EMAIL';
const String groupChannelId = 'grouped channel id';
const String groupChannelName = 'grouped channel name';
const String groupChannelDescription = 'grouped channel description';
// example based on https://developer.android.com/training/notify-user/group.html
const AndroidNotificationDetails firstNotificationAndroidSpecifics =
AndroidNotificationDetails(
groupChannelId, groupChannelName, groupChannelDescription,
importance: Importance.max,
priority: Priority.high,
groupKey: groupKey);
const NotificationDetails firstNotificationPlatformSpecifics =
NotificationDetails(android: firstNotificationAndroidSpecifics);
await flutterLocalNotificationsPlugin.show(1, 'Alex Faarborg',
'You will not believe...', firstNotificationPlatformSpecifics);
const AndroidNotificationDetails secondNotificationAndroidSpecifics =
AndroidNotificationDetails(
groupChannelId, groupChannelName, groupChannelDescription,
importance: Importance.max,
priority: Priority.high,
groupKey: groupKey);
const NotificationDetails secondNotificationPlatformSpecifics =
NotificationDetails(android: secondNotificationAndroidSpecifics);
await flutterLocalNotificationsPlugin.show(
2,
'Jeff Chang',
'Please join us to celebrate the...',
secondNotificationPlatformSpecifics);
// Create the summary notification to support older devices that pre-date
/// Android 7.0 (API level 24).
///
/// Recommended to create this regardless as the behaviour may vary as
/// mentioned in https://developer.android.com/training/notify-user/group
const List<String> lines = <String>[
'Alex Faarborg Check this out',
'Jeff Chang Launch Party'
];
const InboxStyleInformation inboxStyleInformation = InboxStyleInformation(
lines,
contentTitle: '2 messages',
summaryText: 'janedoe@example.com');
const AndroidNotificationDetails androidPlatformChannelSpecifics =
AndroidNotificationDetails(
groupChannelId, groupChannelName, groupChannelDescription,
styleInformation: inboxStyleInformation,
groupKey: groupKey,
setAsGroupSummary: true);
const NotificationDetails platformChannelSpecifics =
NotificationDetails(android: androidPlatformChannelSpecifics);
await flutterLocalNotificationsPlugin.show(
3, 'Attention', 'Two messages', platformChannelSpecifics);

您是否确保负载 (chat_index
) 中的 payload.data.chat_index
在同一组中的通知之间唯一。您将此用作传递给 id
的 FlutterLocalNotificationsPlugin.show
。如果它们都具有相同的 chat_index
(ID),那可能是一个问题。您也可以在通知进来时在本地随机生成一个数字,它不需要在有效负载中。
此外,您可能需要升级到 6.0.0
,因为您落后 2 个主要版本。您可以使用错误修复,但这些新版本可能都与空安全相关。
