How to add serializer in dart to convert iso 8601 to datetime object?
In dart I want to do this:
var s = "2018-11-23T04:25:41.9241411Z"; // string comes from a json but represented here for simplicity like this
var d = DateTime.parse(s);
but it throws a null.
Dart can't seem to parse iso 8601 date time formats. I've found a custom serializer called "Iso8601DateTimeSerializer" but how do I add it to my flutter app?
links: https://reviewable.io/reviews/google/built_value.dart/429#-
The instructions here only indicate adding it to dart using "SerializersBuilder.add" but I'm a newbie and cant find out how?

The problem is that Dart's DateTime.parse only accepts up to six digits of fractional seconds, and your input has seven.
... and then optionally a '.' followed by a one-to-six digit second fraction.
You can sanitize your input down to six digits using something like:
String restrictFractionalSeconds(String dateTime) =>
dateTime.replaceFirstMapped(RegExp("(.d{6})d+"), (m) => m[1]);
Maybe the parse function should just accept more digits, even if they don't affect the value.

Just to add to Irn's answer. You need to add some escapes for the regex to work properly.
String restrictFractionalSeconds(String dateTime) =>
dateTime.replaceFirstMapped(RegExp("(\.\d{6})\d+"), (m) => m[1]);
