How to get last midnight in Dart?

Question

I guess this is pretty common task in most languages, however it was not clear to me how to get this done in my Flutter app. How to retrieve DateTime object of the last midnight in Dart? Or potentially, any particular time today / tomorrow / yesterday?

Answer 1

This should do the same

var now = DateTime.now(); var lastMidnight = DateTime(now.year, now.month, now.day); 

You can use this way to get different times of this day

var tomorrowNoon = DateTime(now.year, now.month, now.day + 1, 12);  var yesterdaySixThirty = DateTime(now.year, now.month, now.day - 1, 6, 30); 

Depending on what you want can absolute values be more safe because adding/subtracting Duration can result in surprises because of leap years and daylight saving time.

Answer 2

Try this package Jiffy, uses the simplicity of momentjs syntax. See below

To get last midnight

var lastMidnight = Jiffy().subtract(days: 1).startOf(Units.DAY);  print(lastMidnight.dateTime); // 2019-10-20 00:00:00.000 //or you can also format it print(lastMidnight.yMMMMEEEEdjm); // Sunday, October 20, 2019 12:00 AM
