Flutter学习之Calendar、Time自带组件和第三方组件学习

第三方日期、时间选择组件使用的是flutter_datetime_picker

class _SSLCalendarState extends State<SSLCalendar> {
  var _now = DateTime.now();
  var _time = TimeOfDay(hour: 12, minute: 20);
  _showDatePicker() async{

    var result = await showDatePicker(
        context: context,
        initialDate: _now,
        firstDate: DateTime(1980),
        lastDate: DateTime(2222)
    );

    setState(() {
      if (result != null){
        _now = result;
      }
    });
    print(result);

  }

  _showTimePicker() async{
    var result = await showTimePicker(
        context: context,
        initialTime: _time
    );
    print(result);
    setState(() {
      if (result != null){
        _time = result;
      }
    });


  }
