I'm trying to parse a Date signUpDate field from MongoDb User object received via http request into a Flutter DateTime signUpDate but it always fails. In my User Schema I have signUpDate: { type: Date, required: false, default: Date.now },. In my Flutter factory User.fromMongoDB(Map<String, dynamic> map) helper I'm using signUpDate: DateTime.parse(map['signUpDate']). When printing http response signUpDate is "signUpDate":"2021-12-15T11:10:01.521Z". Is it just the format coming back from mongo not parsable by DateTime parser or I'm parsing it wrongly?
Many thanks.
Here the code for parsing ISO8601 string to Date time just passing what format you need.
import 'package:intl/intl.dart';
void main() {
var data = "2021-12-15T11:10:01.521Z";
DateTime dateTime = getFormattedDateFromFormattedString(
value: data,
currentFormat: "yyyy-MM-ddTHH:mm:ssZ",
desiredFormat: "yyyy-MM-dd HH:mm:ss");
print(dateTime); //2021-12-15 11:10:01.000
}
getFormattedDateFromFormattedString(
{required value,
required String currentFormat,
required String desiredFormat,
isUtc = false}) {
DateTime? dateTime = DateTime.now();
if (value != null || value.isNotEmpty) {
try {
dateTime = DateFormat(currentFormat).parse(value, isUtc).toLocal();
} catch (e) {
print("$e");
}
}
return dateTime;
}
