flutter_localizations: # 添加国际化
      sdk: flutter         # 添加

MaterialApp下

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

日期组件

// 调用函数打开
                                    showDatePicker(
                                      //locale: const Locale('zh'),
                                      context: context,
                                      initialDate: new DateTime.now(),
                                      firstDate: new DateTime.now().subtract(new Duration(days: 30)), // 减 30 天
                                      lastDate: new DateTime.now().add(new Duration(days: 30)),       // 加 30 天
                                      builder: (BuildContext context, Widget child) {
                                        return Localizations(
                                            locale: const Locale('zh'),
                                            child: child,
                                            delegates: <LocalizationsDelegate>[
                                              GlobalMaterialLocalizations.delegate,
                                              GlobalWidgetsLocalizations.delegate,
                                            ]
                                        );
                                      }
                                    ).then((DateTime val) {
                                      _date.text = formatDate(val);
                                      setState(() {
                                      });
                                    }).catchError((err) {
                                      print(err);
                                    });

时间（未测试）

new MaterialButton(
    child: new Text('选择时间'),
    onPressed: () {
        showTimePicker(
            context: context,
            initialTime: new TimeOfDay.now(),
        ).then((val) {
            print(val);
        }).catchError((err) {
            print(err);
        });
    },
)
