article 2025/3/15 13:19:56

在开发遇到设置生日等信息需要选择日期，这里用到的是CupertinoDatePicker

iOS效果的日期、时间选择器

一、效果图

运行后效果图如下

在这里插入图片描述

二、代码实现

我们需要调用底部弹窗显示

//显示底部弹窗
  static void bottomSheetDialog(
    BuildContext context,
    Widget widget, {
    bool? isScrollControlled,
    bool? enableDrag,
    Color? backgroundColor,
  }) {
    showModalBottomSheet(
      context: context,
      isScrollControlled: isScrollControlled ?? true,
      enableDrag: enableDrag ?? true,
      backgroundColor: backgroundColor ?? Colors.white,
      builder: (ctx) {
        return widget;
      },
    );
  }

生日日期选择
ProfileBirthdayPicker

class ProfileBirthdayPicker extends StatefulWidget {
  const ProfileBirthdayPicker({
    Key? key,
    required this.confirmPressed,
  }) : super(key: key);

  final Function(String date) confirmPressed;

  @override
  State<ProfileBirthdayPicker> createState() => _ProfileBirthdayPickerState();
}

class _ProfileBirthdayPickerState extends State<ProfileBirthdayPicker> {
  String _datePickerDate = "";

  @override
  Widget build(BuildContext context) {
    return Container(
      height: 256.0,
      color: Colors.white,
      child: Column(
        mainAxisAlignment: MainAxisAlignment.start,
        crossAxisAlignment: CrossAxisAlignment.center,
        children: [
          _buildButtonRow(context),
          Expanded(
            child: CupertinoDatePicker(
              dateOrder: DatePickerDateOrder.ymd,
              mode: CupertinoDatePickerMode.date,
              initialDateTime: DateTime.now(),
              onDateTimeChanged: (date) {
                print('onDateTimeChanged - $date');
                String dateString =
                    DateUtil.formatDate(date, format: "yyyy-MM-dd");
                _datePickerDate = dateString;
              },
            ),
          ),
        ],
      ),
    );
  }

  Widget _buildButtonRow(BuildContext context) {
