dateTimeFormat static method

String dateTimeFormat(BuildContext context, { required Object? time, FormatFn? customFormat, HmsFormat? hmsAddFormat, })

日期格式化: 且会根据不同国家显示不同的样式 默认格式：2023/10/06 12:56:34 customFormat格式是：日期格式化，DateFormat.yMd，DateFormat.Md，DateFormat.yMMMMd hmsAddFormat: 添加时分秒的格式化样式 time，可以是 DateTime类型，String，int类型为时间戳
