flutter - 如何在文本字段的点击而不是键盘上显示日期选择器？

Question

希望在单击 TextFormField 而不是键盘时显示日期选择器。我尝试使用 GestureDetector 但没有按预期工作。

DateTime _date = new DateTime.now();
TimeOfDay _time = new TimeOfDay.now();

Future<Null> _selectedDate(BuildContext context) async {
  final DateTime picked = await showDatePicker(
      context: context,
      initialDate: _date,
      firstDate: new DateTime(2016),
      lastDate: new DateTime(2019));

  if (picked != null && picked != _date) {
    print("Date selected ${_date.toString()}");
    setState(() {
      _date = picked;
    });
  }
}
 ......
new GestureDetector(

       onTap: (){
         _selectedTime(context);
             },
            child:
             new TextFormField(
              initialValue: convertToDate(_date),
                decoration: const InputDecoration(
                  icon: const Icon(Icons.calendar_today),
                  hintText: 'Enter your date of event',
                  labelText: 'Date',
                ),
                keyboardType: null,
              ),
            ),

你可以用 AbsorbPointer 包装你的 TextField ，所以你的小部件树看起来像这样:

GestureDetector(
  onTap:()=>showDialog(),
  child:AbsorbPointer(
    child: MyTextField(),
  )
)
