How can i convert a DateTime variable "2022-09-29T07:26:52.000Z" to seconds in dart flutter?

I have a variable in dart string and would like to convert it all to seconds or minutes….

String x = "2022-09-29T07:26:52.000Z"

I want the opposite of this code below

final newYearsDay =
    DateTime.fromMillisecondsSinceEpoch(1640979000000, isUtc:true);
print(newYearsDay); // 2022-01-01 10:00:00.000Z

I want to be able to get this back to seconds from the current timedate formart

>Solution :

You can convert your string to a datetime by using intl like this:

String x = "2022-09-29T07:26:52.000Z";
var dateTime = DateFormat('yyyy-MM-ddThh:mm:ss').parse(x);

and for get the number of milliseconds since the Unix epoch :

print("numbers= ${dateTime.millisecondsSinceEpoch}")
