本地通知抖动

Question

谁能告诉我如何使用本地通知插件在 flutter 中安排通知的代码。尝试了 git 存储库中的示例购买它对我不起作用，虽然正常通知有效但我如何安排它在特定时间像提醒一样？

Answer 1

来自 plugin sample code 如果您想安排通知，您必须使用这样的代码：

/// Schedules a notification that specifies a different icon, sound and vibration pattern
  Future _scheduleNotification() async {
    var scheduledNotificationDateTime =
        new DateTime.now().add(new Duration(seconds: 5));
    var vibrationPattern = new Int64List(4);
    vibrationPattern[0] = 0;
    vibrationPattern[1] = 1000;
    vibrationPattern[2] = 5000;
    vibrationPattern[3] = 2000;

    var androidPlatformChannelSpecifics = new AndroidNotificationDetails(
        'your other channel id',
        'your other channel name',
        'your other channel description',
        icon: 'secondary_icon',
        sound: 'slow_spring_board',
        largeIcon: 'sample_large_icon',
        largeIconBitmapSource: BitmapSource.Drawable,
        vibrationPattern: vibrationPattern,
        color: const Color.fromARGB(255, 255, 0, 0));
    var iOSPlatformChannelSpecifics =
        new IOSNotificationDetails(sound: "slow_spring_board.aiff");
    var platformChannelSpecifics = new NotificationDetails(
        androidPlatformChannelSpecifics, iOSPlatformChannelSpecifics);
    await flutterLocalNotificationsPlugin.schedule(
        0,
        'scheduled title',
        'scheduled body',
        scheduledNotificationDateTime,
        platformChannelSpecifics);
  }

您必须关注的部分是：

// Schedule a notification in 5 secs from now
var scheduledNotificationDateTime =
        new DateTime.now().add(new Duration(seconds: 5));

如果您不确定为显示通知而要设置的本机项目，我建议您克隆插件存储库并尝试其示例。

/// IMPORTANT: running the following code on its own won't work as there is setup required for each platform head project.

/// Please download the complete example app from the GitHub repository where all the setup has been done

Answer 2

const AndroidNotificationDetails androidPlatformChannelSpecifics = AndroidNotificationDetails('repeating channel id','repeating channel name', 'repeating description');
const NotificationDetails platformChannelSpecifics = NotificationDetails(android: androidPlatformChannelSpecifics);
await flutterLocalNotificationsPlugin.periodicallyShow(0, 'repeating title', 'repeating body', RepeatInterval.everyMinute, platformChannelSpecifics, androidAllowWhileIdle: true);

你可以使用periodicallyShowflutter_local_notifications
