4 years ago 没有指定pickerMode，默认是 DateTimePickerMode.date，dateFormat 的值不合法，H、m、s 之间的分隔符不包括 "/"，v1.0.23版本新增了pickerMode的校验，并且添加了分隔符 "/"
No pickerMode is specified, the default is DateTimePickerMode.date, the value of dateFormat is invalid, and the separator between H, m, and s does not include"/", pickerMode verification is added in v1.0.23, and a separator is added /.

DatePicker.showDatePicker(context, dateFormat: 'HH/mm/ss');
When I press the button I get this error: The following NoSuchMethodError was thrown building DatePickerWidget(dirty, state: _DatePickerWidgetState#7c286): The getter 'last' was called on null.
