Flutter 有没有办法制作动态时间戳，打印 10 分钟前、1 小时前或 2 个月前的内容

我已经将我的lastseen时间戳发送到firebase中，如何用我已经发送到firestore的时间戳来扣除当前时间戳。这会给我Last Seen 15 分钟前，或者可能是很长一段时间，看起来像Last Seen 20 days ago 那样。我已经尝试在 pub.dev 中使用 timeago 包，但我不知道在持续时间内应该替换什么。代码看起来像这样

final fifteenAgo = DateTime.now().subtract(Duration(minutes: 15));

我应该用什么替换分钟？

这是我从 firestore 检索到的数据

i already send my lastseen timestamp into firebase and how can i deduct the current timestamp with the one that i already sent to firestore. that will give me Last Seen 15 minutes ago, or maybe a long time that look like this Last Seen 20 days ago that did it. im already try to use the timeago package in pub.dev but i dont know what should i replace in the duration. the code look like this

final fifteenAgo = DateTime.now().subtract(Duration(minutes: 15));

what should i replace the minutes with ?

this is the data that i've been retrieve from firestore

final DateTime lastSeen = DateTime.parse(yourDataFromFireStore);
final Duration timePassed = DateTime.now().difference(lastSeen);

timePassed 变量将保存自上次查看以来经过的持续时间。然后，您必须定义一个函数，该函数获取持续时间并返回应显示的正确字符串，例如“5 天前”或其他内容。

final DateTime lastSeen = DateTime.parse(yourDataFromFireStore);
final Duration timePassed = DateTime.now().difference(lastSeen);

The timePassed variable will then hold the duration that passed since it was last seen. You will then have to define a function that takes the duration and returns the proper string that should be displayed like for example "5 days ago" or something else.
