showDatePicker static method

void showDatePicker(BuildContext context, { DateMode mode = DateMode.YMD, PDuration? selectDate, PDuration? maxDate, PDuration? minDate, Suffix? suffix, PickerStyle? pickerStyle, DateCallback? onChanged, DateCallback? onConfirm, dynamic onCancel(bool isCancel)?, bool overlapTabBar = false, })

时间选择器 Suffix : 每列时间对应的单位 默认：中文常规 Suffix(years: '年',month: '月'); selectDate : 初始化选中时间 默认现在 PDuration.now(); PDuration.parse(DateTime.parse('20210139')); PDuration(year: 2020,month: 2); maxDate : 最大时间 用法同上 tip: 当只有单列数据，该限制不产生关联 只针对单列item限制，比如 maxDate>day = 3 minDate>day = 10,那么所有的月份都只显示3-10之间 minDate : 最小时间 用法同上 mode : 时间选择器所显示样式 16 种时间样式 默认：DateMode.YMD

  // 解析是否有对应数据

  if ((dateItemModel.day || dateItemModel.year)) {
    if (intEmpty(selectDate.year)) {

    }

    /// 如果有年item ，必须限制
    if (intEmpty(maxDate.year)) maxDate.year = 2100;

    // print('longer >>> ${minDate.year}');

    if (dateItemModel.month || dateItemModel.day) {
