How to implement multiple local notification in Flutter?
You need to change channelID for each notification you don't want to stack.
flutterLocalNotificationsPlugin.showWeeklyAtDayAndTime(your_channelID_goes_here, widget.title, '', Day.Monday, time, platformChannelSpecifics, payload: widget.title);
Just change the channelID. You have put it as 0. change it is as 0,1,2,3 then you will get multiple notifications
flutterLocalNotificationsPlugin.showWeeklyAtDayAndTime("change Here channelID as 0 or 1 or 2 or 3", widget.title,'', Day.Monday,time,platformChannelSpecifics,payload: widget.title);
