注意：无特殊说明，Flutter版本及Dart版本如下： Flutter版本： 1.12.13+hotfix.5 Dart版本： 2.7.0 DatePicker Flutter并没有DatePick

RaisedButton(
  onPressed: () async {
    var result = await showDatePicker(
        context: context,initialDate: DateTime.now(),firstDate: DateTime(2020),lastDate: DateTime(2021));
    print('$result');
  },)

showDatePicker(
  selectableDayPredicate: (DateTime day) {
    return day.difference(DateTime.now()).inDays < 2;
  },...
)

showDatePicker(
  builder: (context,child) {
    return Theme(
      data: ThemeData.dark(),child: child,);
  },...
)

中文支持

dependencies:
  flutter:
    sdk: flutter
  flutter_localizations:
    sdk: flutter

MaterialApp(
  localizationsDelegates: [
    GlobalMaterialLocalizations.delegate,GlobalWidgetsLocalizations.delegate,],supportedLocales: [
    const Locale('zh','CH'),const Locale('en','US'),locale: Locale('zh'),...
)

showDatePicker(
  locale: Locale('zh'),...
)

RaisedButton(
  onPressed: () async {
    showTimePicker(
        context: context,initialTime: TimeOfDay.now());
  },)

showTimePicker(
    context: context,initialTime: TimeOfDay.now(),builder: (context,child) {
      return MediaQuery(
        data: MediaQuery.of(context)
            .copyWith(alwaysUse24HourFormat: true),);
    });

showTimePicker(
    context: context,child) {
      return Localizations(
          locale: const Locale('zh'),delegates: <LocalizationsDelegate>[
            GlobalMaterialLocalizations.delegate,]
      );
    });

 var _dateTime = DateTime.now();
CupertinoDatePicker(
  initialDateTime: _dateTime,onDateTimeChanged: (date) {
    setState(() {
      _dateTime = date;
    });
  },)

time：只显示时间，效果：4 | 14 | PM
date：只显示日期，效果：July | 13 | 2012
dateAndTime：时间和日期都显示，效果： Fri Jul 13 | 4 | 14 | PM

CupertinoDatePicker(
  minimumDate: DateTime.now().add(Duration(days: -1)),maximumDate: DateTime.now().add(Duration(days: 1)),...
)

CupertinoDatePicker(
  use24hFormat: true,...
)

CupertinoTimerPicker(
  onTimerDurationChanged: (Duration duration){
  },)

CupertinoTimerPicker(
  mode: CupertinoTimerPickerMode.hm,...
)

var now = DateTime.now();
return Container(
  height: 200,child: CupertinoTimerPicker(
    initialTimerDuration: Duration(hours: now.hour,minutes: now.minute,seconds: now.second),onTimerDurationChanged: (Duration duration) {},),);
