如何在颤振默认日期选择器中删除时间戳或仅获取日期形式的日期选择器? [英] how to remove time stamp or get only date form datepicker in flutter default datepicker?

问题描述

我正在尝试从 flutter 的默认日期选择器小部件中获取日期，但是当我选择日期时，我有时间使用它.我只想要日期而不是时间.&如果可能，还想更改日期格式.

I am trying to get date from default datepicker widget of flutter but when i select date i get time with it. I only want date not time. & would also like to change date format if possible.

这是我在某处的例子中使用的.

This is what i have used from example somewhere.

DateTime selectedDate = DateTime.now();

Future<Null> _selectDate(BuildContext context) async {
    final DateTime picked = await showDatePicker(
        context: context,
        initialDate: selectedDate,
        firstDate: DateTime(2019),
        lastDate: DateTime(2020));
    if (picked != null && picked != selectedDate)
      setState(() {
        selectedDate = picked;
      });
  }

这是我获取字符串值的地方.它打印为2019-04-16 12:18:06.018950"

This is where I am getting value to string. It prints like "2019-04-16 12:18:06.018950"

child: FlatButton(
                        materialTapTargetSize: MaterialTapTargetSize.shrinkWrap,
                        onPressed: () {
                          _selectDate(context);
                          print("Selected Date = $selectedDate");
                        },
                        child: Text(selectedDate == null
                            ? "Select Date"
                            : selectedDate.toString()),
                      )),

我想要仅日期来自这个2019-04-16 12:18:06.018950"，并更改日期显示格式，如dd-mm-yyyy"

I want only date from this "2019-04-16 12:18:06.018950" and also change the format of date displaying like "dd-mm-yyyy"

这可能吗?

推荐答案

我制作了自定义 DateFormat，您可以使用此代码，然后您将获得输出为:16-04-2019

I make the Custom DateFormat you can use this code then you will get the Output as : 16-04-2019

TextEditingController _datecontroller = new TextEditingController();

var myFormat = DateFormat('d-MM-yyyy');

Future<void> _selectDate(BuildContext context) async {
    final DateTime picked = await showDatePicker(
        context: context,
        initialDate: date,
        firstDate: DateTime(2015, 8),
        lastDate: DateTime(2101));
    setState(() {
      date = picked ?? date;
    });
  }

Inkwell 小部件是这样的

and Inkwell widget goes like this

InkWell(
  onTap: () => _selectDate(context),
  child: IgnorePointer(
    child: TextField(
      controller: _datecontroller,
      decoration: InputDecoration(

        hintText: ('${myFormat.format(date)}'),
      ),

    ),
  ),
),
