flutter开发实战-时间显示刚刚几分钟前几小时前

在开发中经常遇到从服务端获取的时间戳，需要转换显示刚刚、几分钟前、几小时前、几天前、年月日等格式。

一、代码实现

static String timeFormatterChatTimeStamp(int seconds) {try {int nowDateSeconds =(DateTime.now().millisecondsSinceEpoch / 1000).truncate();String anotherDate =DateUtil.formatDateMs(seconds*1000, format: DateFormats.full);String nowDate =DateUtil.formatDateMs(nowDateSeconds*1000, format: DateFormats.full);print("timeFormatterChatTimeStamp ""seconds:${seconds},""nowDateSeconds:${nowDateSeconds},""anotherDate:${anotherDate},""nowDate:${nowDate}");//为了判断当前时间是否为未来时间if (seconds > nowDateSeconds) {return anotherDate;}List<String> anotherDateList = anotherDate.split(" ");List<String> nowDateList = nowDate.split(" ");if (anotherDateList.length == 2 && nowDateList.length == 2) {String nowDateYMD = nowDateList[0];String nowDateHMS = nowDateList[1];String anotherDateYMD = anotherDateList[0];String anotherDateHMS = anotherDateList[1];List<String> anotherDateYMDList = anotherDateYMD.split("-");List<String> nowDateYMDList = nowDateYMD.split("-");List<String> anotherDateHMSList = anotherDateHMS.split(":");List<String> nowDateHMSList = nowDateHMS.split(":");String anotherDateY = anotherDateYMDList[0];String anotherDateM = anotherDateYMDList[1];String anotherDateD = anotherDateYMDList[2];String nowDateY = nowDateYMDList[0];String nowDateM = nowDateYMDList[1];String nowDateD = nowDateYMDList[2];String anotherDateH = anotherDateHMSList[0];String anotherDateMi = anotherDateHMSList[1];String anotherDateS = anotherDateHMSList[2];int year = int.parse(anotherDateY) - int.parse(nowDateY);if (year < 0) {// 过去（今年以前）return "${anotherDateY}年${anotherDateM}月${anotherDateD}日 ${anotherDateH}:${anotherDateMi}";} else {if (nowDateY == anotherDateY) {// 今年return "${anotherDateM}月${anotherDateD}日 ${anotherDateH}:${anotherDateMi}";} else {return "${anotherDateY}年${anotherDateM}月${anotherDateD}日 ${anotherDateH}:${anotherDateMi}";}}} else {return anotherDate;}} catch (e) {return "${seconds}";}}

二、小结
flutter开发实战-格式化时间显示刚刚几分钟前几小时前等

从服务端获取的时间戳，需要转换显示刚刚、几分钟前、几小时前、几天前、年月日等格式。用到了DateUtil。
