Flutter中flutter_local_notifications的zonedSchedule通知在安卓模拟器不触发

我在Android API33模拟器上运行Flutter应用，使用flutter_local_notifications包。普通通知（「Show plain notification with payload」功能）可正常显示，但点击「Schedule notification to appear in 5 seconds」触发的定时通知无任何反应，且无报错信息。

已调整的定时通知代码 #

为避免额外权限，我将androidScheduleMode改为inexact模式，定时通知代码如下：

Future<void> _zonedScheduleNotification() async {
    final nowDttm =
        tz.TZDateTime.now(tz.local).add(const Duration(seconds: 5));
    print('Scheduled: $nowDttm');

    await flutterLocalNotificationsPlugin.zonedSchedule(
        0,
        'scheduled title',
        'scheduled body',
        nowDttm,
        const NotificationDetails(
            android: AndroidNotificationDetails(
                'your channel id', 'your channel name',
                channelDescription: 'your channel description')),
        androidScheduleMode: AndroidScheduleMode.inexactAllowWhileIdle, //changed from exact
        uiLocalNotificationDateInterpretation:
            UILocalNotificationDateInterpretation.absoluteTime);
  }

正常工作的普通通知代码 #

普通通知可正常显示，其实现代码如下：

Future<void> _showNotification() async {
    const AndroidNotificationDetails androidNotificationDetails =
        AndroidNotificationDetails('your channel id', 'your channel name',
            channelDescription: 'your channel description',
            importance: Importance.max,
            priority: Priority.high,
            ticker: 'ticker');
    const NotificationDetails notificationDetails =
        NotificationDetails(android: androidNotificationDetails);
    await flutterLocalNotificationsPlugin.show(
        id++, 'plain title', 'plain body', notificationDetails,
        payload: 'item x');
  }

已确认的配置项 #

• 应用已获取通知权限（普通通知正常显示可佐证）
• 时区初始化正确，代码如下：

tz.initializeTimeZones();
final String timeZoneName = await FlutterTimezone.getLocalTimezone();
tz.setLocalLocation(tz.getLocation(timeZoneName));

AndroidManifest.xml配置 #

            android:name="flutterEmbedding"
            android:value="2" />
    </application>
  
</manifest>

请问我遗漏了什么配置？该如何排查此定时通知不触发的问题？
