How to show local notification from sqlite while app is closed in flutter?

Answer 1

尝试 flutter_local_notifications , 来自 sample example app 的代码片段.

  Future<void> _showNotification() async {
    var androidPlatformChannelSpecifics = AndroidNotificationDetails(
        'your channel id', 'your channel name', 'your channel description',
        importance: Importance.Max, priority: Priority.High, ticker: 'ticker');
    var iOSPlatformChannelSpecifics = IOSNotificationDetails();
    var platformChannelSpecifics = NotificationDetails(
        androidPlatformChannelSpecifics, iOSPlatformChannelSpecifics);
    await flutterLocalNotificationsPlugin.show(
        0, 'plain title', 'plain body', platformChannelSpecifics,
        payload: 'item x');
  }

它还可以选择安排通知，并根据点击的通知进行路由。
