我正在使用Flutter本地通知在我的应用中显示预定通知。但不幸的是,当应用程序处于终止状态时,它无法正常工作。
这是我的代码:
class Notifications {
static final FlutterLocalNotificationsPlugin _notifications =
FlutterLocalNotificationsPlugin();
static Future<NotificationDetails> _notificationDetails() async {
return const NotificationDetails(
android: AndroidNotificationDetails(
'weekly notification channel id',
'weekly notification channel name',
channelDescription: 'weekly notification description',
playSound: true,
sound: RawResourceAndroidNotificationSound('azan1'),
importance: Importance.high,
),
iOS: IOSNotificationDetails(sound: 'azan1.mp3', presentSound: true));
}
static void init() async {
tz.initializeTimeZones();
const AndroidInitializationSettings android =
AndroidInitializationSettings('@mipmap/ic_launcher');
const IOSInitializationSettings iOS = IOSInitializationSettings();
InitializationSettings settings =
const InitializationSettings(android: android, iOS: iOS);
await _notifications.initialize(settings);
final String locationName = await FlutterNativeTimezone.getLocalTimezone();
tz.setLocalLocation(tz.getLocation(locationName));
}
static void showScheduledNotification(
int id, {
required DateTime scheduledDate,
String? title,
String? body,
String? payload,
}) async {
await _notifications.zonedSchedule(
id,
'Azan Time',
'$body Prayer Time',
_scheduleDaily(
Time(scheduledDate.hour, scheduledDate.minute, scheduledDate.second)),
await _notificationDetails(),
androidAllowWhileIdle: true,
uiLocalNotificationDateInterpretation:
UILocalNotificationDateInterpretation.absoluteTime,
matchDateTimeComponents: DateTimeComponents.time,
payload: payload,
);
}
static tz.TZDateTime _scheduleDaily(Time time) {
tz.TZDateTime now = tz.TZDateTime.now(tz.local);
tz.TZDateTime schdeuledDate = tz.TZDateTime(tz.local, now.year, now.month,
now.day, time.hour, time.minute, time.second);
return schdeuledDate.isBefore(now)
? schdeuledDate.add(const Duration(days:1))
: schdeuledDate;
}
static Future<void> cancelNotification(int id) async {
await _notifications.cancel(id);
}
static Future<void> cancelAllNotifications() async {
await _notifications.cancelAll();
}
}
我也已经在 Android.xml 文件中添加了所有属性。但如果有人知道解决此问题的方法,请回答此问题。
