Dart: previous and next weekday name

Question

Is there any way in dart to find next and previous weekday name? Such as, today is say Friday, so previous day was Thursday and next day will Saturday. Can I programmatically handle that?

At the time I posted this it's Thursday where I live

For yesterday:

print(DateFormat("EEEE").format(DateTime.now().add(Duration(days: -1))));

output:

Wednesday

For tomorrow:

print(DateFormat("EEEE").format(DateTime.now().add(Duration(days: 1))));

Output:

Friday

The output might be different depending on your locale.

This needs

import 'package:intl/intl.dart';

to work.

This is dangerous on the days that are 23 or 25 hours long (at DST shifts). See my videos https://youtu.be/usFSVUEadyo and https://youtu.be/LpoBYgzKVwU for details. – Randal Schwartz Jul 01 '22 at 03:38

in your pubspec.yaml file, dependencies section. add intl dependency like so

dependencies:
  intl: ^latest version

and then import :

import 'package:intl/intl.dart';

now you can use DateFormat as you wish, here is an example :

print(DateFormat('EEEE').format(DateTime.now())); // prints Tuesday
print(DateFormat('EEEE').format(DateTime.now().subtract(Duration(days: 1))));// prints Monday
print(DateFormat('EEEE').format(DateTime.now().add(Duration(days: 1)))); // prints Wednesday

Dart: previous and next weekday name
