一、Flutter日期组件:

var _datetime=DateTime.now();
	
_showDatePicker() async{
    var date =await showDatePicker(
      context: context,
      initialDate: _datetime,
      firstDate:DateTime(1900),
      lastDate:DateTime(2050)      
    );
    if(date==null) return;
    print(date);
    setState(() {
       _datetime=date!;
    });
  }

二、Flutter时间组件:

var _time=TimeOfDay(hour: 9,minute: 20); 

_showTimePicker() async{
    var time =await showTimePicker(
      context: context,   
      initialTime:  _time      
    );		
    if(time==null) return;
    print(time);
    setState(() {
       this._time=time!;
    });
  }
  
  
  Column(
        mainAxisAlignment: MainAxisAlignment.center,
        children: <Widget>[
          Row(
            mainAxisAlignment: MainAxisAlignment.center,
            children: <Widget>[
              InkWell(
                child: Row(
                  children: <Widget>[
                    Text("${formatDate(_datetime, [yyyy, '-', mm, '-', dd])}"),
                    Icon(Icons.arrow_drop_down)
                  ],
                ),
                onTap: _showDatePicker,
              ), 
              InkWell(
                child: Row(
                  children: <Widget>[
                    Text("${this._time.format(context)}"),
                    Icon(Icons.arrow_drop_down)
                  ],
                ),
                onTap: _showTimePicker,
              ),
            ],
          )
        ],
