Flutter：showDatePicker改变颜色

Question

我正在尝试更改日期选择器的颜色，但其中仍然有蓝色。我尝试了很多，但找不到更改蓝色的代码（见下文）。

文本：输入日期、下划线以及取消和确定按钮都应为青色。

这是我到目前为止的代码。感谢您的支持！

  TextEditingController _dateController = new TextEditingController();
  DateTime selectedDate = DateTime.now();
  var myFormat = DateFormat('d-MM-yyyy');
  Future<void> _selectDate(BuildContext context) async {
    final DateTime picked = await showDatePicker(
        context: context,
        initialDate: selectedDate,
        firstDate: DateTime(1930),
        lastDate: DateTime(2022),
        builder: (BuildContext context, Widget child) {
          return Theme(
            data: ThemeData.light().copyWith(
              colorScheme: ColorScheme.fromSwatch(
                primarySwatch: Colors.teal,
                primaryColorDark: Colors.teal,
                accentColor: Colors.teal,
              ),
            dialogBackgroundColor:Colors.white,
          ),
          child: child,
       );
    },
    );
    if (picked != null && picked != selectedDate)
      setState(() {
        selectedDate = picked;
      });
  }

试试这个

TextEditingController _dateController = new TextEditingController();
DateTime selectedDate = DateTime.now();
var myFormat = DateFormat('d-MM-yyyy');
Future<void> _selectDate(BuildContext context) async {
final DateTime picked = await showDatePicker(
    context: context,
    initialDate: selectedDate,
    firstDate: DateTime(1930),
    lastDate: DateTime(2022),
    builder: (BuildContext context, Widget child) {
      return Theme(
        data: ThemeData.light().copyWith(
          colorScheme: ColorScheme.fromSwatch(
            primarySwatch: Colors.teal,
            primaryColorDark: Colors.teal,
            accentColor: Colors.teal,
          ),
        dialogBackgroundColor:Colors.white,
      ),
      child: child,
   );
},
);
if (picked != null && picked != selectedDate)
  setState(() {
    selectedDate = picked;
  });
}
