Oracle datetime format in dart language - dart

Question

I get from API a json object with datetime field in format:
"date": "6/23/2018 12:00:00 AM",
How to transform it to valid date time object in Dart?
While parsing it I get an error
Invalid date format
class User {
int id;
DateTime date;
User({this.id,this.date});
factory User.fromJson(Map<String, dynamic> json) {
return User(
id: json['id'],
date: DateTime.parse(json['date'])
);
}
}

Answer 1

final dateRegExp =
RegExp(r'(\d{1,2})/(\d{1,2})/(\d{4}) (\d{2}):(\d{2}):(\d{2}) (AM|PM)');
var match = dateRegExp.firstMatch('6/23/2018 12:00:00 AM');
var result = DateTime(
int.parse(match[3]),
int.parse(match[1]),
int.parse(match[2]),
int.parse(match[4]) + (match[7] == 'AM' ? 0 : 12),
int.parse(match[5]),
int.parse(match[6]),
);
print(result);

Answer 2

You can do this in a simpler way by using this package, Jiffy. It tries to mimic the simplicity of momentjs
To get the DateTime object
DateTime d = Jiffy("6/23/2018 12:00:00 AM", "MM/dd/yyyy hh:mm:ss a").dateTime;
You can also format it
Jiffy("6/23/2018 12:00:00 AM", "MM/dd/yyyy hh:mm:ss a").format("yyyy, MM dd"); // 2018, 06 23
// You can also use default formats
Jiffy("6/23/2018 12:00:00 AM", "MM/dd/yyyy hh:mm:ss a").yMMMEdjm; // Sat, Jun 23, 2018 12:00 AM
