更改 Cupertino 日期选择器的文本颜色

Question

Attached below is my current code for changing the text color of CupertinoDatePicker:

Container(
                decoration:
                    BoxDecoration(borderRadius: BorderRadius.circular(12)),
                height: MediaQuery.of(context).size.height * 0.18,
                child: CupertinoTheme(
                  data: CupertinoThemeData(
                    textTheme: CupertinoTextThemeData(
                        pickerTextStyle: TextStyle(
                      color: Color(0xffB59CCF),
                    )),
                  ),
                  child: CupertinoDatePicker(

However, the color hasn't changed as shown below:

My theme in main.dart is as follows:

class MyApp extends StatelessWidget {
  // This widget is the root of your application.
  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      theme: ThemeData(
        textTheme: TextTheme(
          bodyText1: TextStyle(),
          bodyText2: TextStyle(),
        ).apply(
            bodyColor: Colors.white.withOpacity(0.87),
            displayColor: Colors.white.withOpacity(0.87)),
        primaryColor: Colors.white,
        secondaryHeaderColor: Colors.white.withOpacity(0.60),
        backgroundColor: Color(0xff111016),
        elevatedButtonTheme: ElevatedButtonThemeData(
          style: ElevatedButton.styleFrom(
              padding: EdgeInsets.all(15),
              shape: CircleBorder(),
              elevation: 6,
              onPrimary: Color(0xff04072E),
              primary: Colors.yellow[100],
              textStyle: TextStyle(fontSize: 21)),
        ),

I'm not sure what is causing the text color of CupertinoDatePicker to be black, but I would like it to change its color. Any help is appreciated! Thanks!

After changing to dateTimePickerTextStyle, the following occurs:

Answer 1

What you are looking for is the

dateTimePickerTextStyle: TextStyle(color: Colors.white),

This property is part of the CupertinoTextThemeData .

So your code should be like this,

CupertinoTheme(
  data: CupertinoThemeData(
    textTheme: CupertinoTextThemeData(
      dateTimePickerTextStyle: TextStyle(color: Colors.white),
    ),
  ),
  child: CupertinoDatePicker(
    onDateTimeChanged: (_) {},
  ),
)

From the official documentation,

Content texts are shown with CupertinoTextThemeData.dateTimePickerTextStyle.

Answer 2

Use dateTimePickerTextStyle instead of pickerTextStyle

Here is the working code

          CupertinoTheme(
            data: CupertinoThemeData(
              textTheme: CupertinoTextThemeData(
                dateTimePickerTextStyle: TextStyle(
                  color: Colors.red,
                ),
              ),
            ),
            child: CupertinoDatePicker(
              minimumDate: DateTime.now(),
              minuteInterval: 1,
              mode: CupertinoDatePickerMode.dateAndTime,
              onDateTimeChanged: (DateTime dateTime) {
                print("dateTime: ${dateTime}");
              },
            ),
          );

                              initialDateTime: DateTime.now(),
                              maximumDate: new DateTime(2050, 12, 30),
                              minimumYear: 2010,

                                setState(() {
                                  tanggalController.text =
                                      newdate.formatDateView();
                                });
                              }),
                        ),
                      );
