The error is simple
import 'package:intl/intl.dart';
DateFormat.d().format(DateTime.now().toString())
Return
The method 'd' isn't defined for the class 'DateFormat'. Try correcting the name to the name of an existing method, or defining a method named 'd'.
Is clear what happen but how can i fix it?
Try use this to get a day of week (like at monday)
Add dependency intl
intl: ^0.16.0 // Or the last version
Code:
import 'package:intl/intl.dart';
DateFormat.EEEE().format(DateTime.now())
