How to convert DateTime to Timestamp before saving in Firestore in Flutter?

Question

I picked a "date" form datePicker and wanted to save that date (type as DateTime) to Firestore in Timestamp type. I used Firestore.fromDate(date) but it stores data in Firestore as a map(nanoseconds, seconds).

Answer 1

Use the Firebase Timestamp class as:

Timestamp.fromMicrosecondsSinceEpoch(myDateTime.microsecondsSinceEpoch)

There are many other constructors, take a look at the docs.
