DateTime now = DateTime.now(); String formattedDate = DateFormat('yyyy-MM-dd HH:mm:ss').format(now.toUtc().add(Duration(hours: 8))); print(formattedDate); 在上面的代码中,我们使用DateFormat类将当前时间格式化为指定的日期和时间格式。toUtc()方法将时间转换为UTC时间,然后使用add()方法添加指定...
In Flutter, you can get only the date from DateTime by using thetoLocal()method to convert the DateTime object to the local time zone, and then using thetoString()method with a specified format string that only includes the date fields. Here’s an example: DateTime now = DateTime.now();...
一、DateTime 1、格式化 //引入import 'package:intl/intl.dart';DateTime date=DateTime(2020,9,1);String dateString=DateFormat("yyyy-MM-dd").format(date).toString();print(dateString);//2020-09-01DateTime date=DateTime.now();String dateString=DateFormat("yyyy-MM-dd HH:mm:ss").format(date)....
dart中不包含时区设置,格式化输出时无法按照时区偏移输出时间。 import'package:intl/intl.dart';/// 扩展DateFormat,增加时区偏移extension DateZoneFormat on DateFormat{/// 时区 [-11] 到 [+13]StringformatZone(DateTime date,{required int zoneOffset}){vardateUTC=date.toUtc();varnewDate=dateUTC.add(...
