Question

我可以在应用启动时发出本地通知，但不能在特定时间发出预定通知，以下代码是我每次打开应用程序时都会触发的本地通知

local_notification.dart

Code

main.dart

import 'package:flutter_local_notifications/flutter_local_notifications.dart';
import 'package:meta/meta.dart';

NotificationDetails get _noSound {
  final androidChannelSpecifics = AndroidNotificationDetails(
    'silent channel id',
    'silent channel name',
    'silent channel description',
    playSound: false,
  );
  final iOSChannelSpecifics = IOSNotificationDetails(presentSound: false);

  return NotificationDetails(androidChannelSpecifics, iOSChannelSpecifics);
}

Future showSilentNotification(
    FlutterLocalNotificationsPlugin notifications, {
      @required String title,
      @required String body,
      int id = 0,
    }) =>
    _showNotification(notifications,
        title: title, body: body, id: id, type: _noSound);

NotificationDetails get _ongoing {
  final androidChannelSpecifics = AndroidNotificationDetails(
    'your channel id',
    'your channel name',
    'your channel description',
    importance: Importance.Max,
    priority: Priority.High,
    ongoing: true,
    autoCancel: false,
  );
  final iOSChannelSpecifics = IOSNotificationDetails();
  return NotificationDetails(androidChannelSpecifics, iOSChannelSpecifics);
}

Future showOngoingNotification(
    FlutterLocalNotificationsPlugin notifications, {
      @required String title,
      @required String body,
      int id = 0,
    }) =>
    _showNotification(notifications,
        title: title, body: body, id: id, type: _ongoing);

Future _showNotification(
    FlutterLocalNotificationsPlugin notifications, {
      @required String title,
      @required String body,
      @required NotificationDetails type,
      int id = 0,
    }) =>
    notifications.show(id, title, body, type);

我的问题是，即使关闭了应用程序，如何在特定时间（例如，晚上10:00）发出预定的通知？我尝试了很多方法，即使调度通知根本不起作用，也无法达到我想要的效果

Answer 1

notifications.schedule(...)而不是notifications.show(...)
