在flutter中的showDatePicker上设置日期后如何显示showTimePicker?

问题描述

我想在我的应用程序中实现提醒功能，该功能可以提醒用户在选定的时间执行特定的任务.我已经实现了 showDatePicker 小部件以选择日期和月份，但是我不确定在 showDatePicker showTimePicker .>

I want to implement a reminder feature in my application which reminds the user to do a particular task at a selected time. I have implemented a showDatePicker widget to select the date and month but i am unsure on how to display a showTimePicker after a date is selected in the showDatePicker

我可以对如何实施提出建议吗?

Could i get a suggestion on how this can be implemented?

代码:

  _selectDate() async {
    final DateTime picker =await showDatePicker(
        context: context,
        initialDate: DateTime.now(),
        firstDate: DateTime(2010),
        lastDate: DateTime(2040)
    );

    if (picker != null) {
      print(picker);
      _daysPageController.jumpToDay(picker);
//        Navigator.pop(context);

//        print(selectedDate);
//       await runJump(selectedDate);
//       return selectedDate;
    }
  }

推荐答案

它非常简单，它创建了一个单个函数，该函数依次调用了showDatePicker()和showTimePicker()方法.

It is very simple, it creates a single function that in sequence calls the methods showDatePicker() and showTimePicker().

Future _selectDayAndTime(BuildContext context) async {

   DateTime _selectedDay = await showDatePicker(
     context: context,
     initialDate: DateTime.now(),
     firstDate: DateTime(2018),
     lastDate: DateTime(2030),
     builder: (BuildContext context, Widget child) => child
   );

   TimeOfDay _selectedTime = await showTimePicker(
     context: context,
     initialTime: TimeOfDay.now(),
   );


   if(_selectedDay != null && _selectedTime != null) {
     //a little check
   }
}
