How to fetch weekday name from date saved in timeStamp in Flutter / Firebase

I am saving my timeStamp to Firestore as DateTime.now(). Now, I need to retrieve from this timeStamp a specific day of the week.

For example to reset some variables every Monday morning.

Please help how it should be done. Many thanks in advance!

Solution

  • Firestore’s timestamp contains a method called toDate() method that will return a dart DateTime object.

    toDate():

    timestamp.toDate(); // e.g 2022-01-10 00:00:00.000

    From the return of the method, you can now use regular Dart solutions. You can use DateFormat library to display it as day of the week.

    DateFormat:

    DateFormat('EEEE').format(date); // e.g Monday
