A easy dart package to decode JSON Web Tokens, and to check and give its expiry dates.

Using #

Decode a token #

The easiest way to use this library is via the top-level function parseJwt().

import 'package:jwt_decode/jwt_decode.dart';

String token = 'eyJ0eXAiOiJKV1QiLCJhbGciOiJIUzI1NiJ9.eyJpc3MiOiJKV1QgRGVjb2RlIiwiaWF0IjoxNjA4NTgxNzczLCJleHAiOjE2NDAxMTc3NzMsImF1ZCI6Ind3dy5qd3RkZWNvZGUuY29tIiwic3ViIjoiQSBzYW1wbGUgSldUIiwibmFtZSI6IlZhcnVuIFMgQXRocmV5YSIsImVtYWlsIjoidmFydW4uc2F0aHJleWFAZ21haWwuY29tIiwicm9sZSI6IkRldmVsb3BlciJ9.vXE9ogUeMMsOTz2XQYHxE2hihVKyyxrhi_qfhJXamPQ';

Map<String, dynamic> payload = Jwt.parseJwt(token);

print(payload);

// After decoding, payload would look like this:
//  payload = {
//    'iss': 'JWT Decode',
//    'iat': 1608581773,
//    'exp': 1640117773,
//    'aud': 'www.jwtdecode.com',
//    'sub': 'A sample JWT',
//    'name': 'Varun S Athreya',
//    'email': 'varun.sathreya@gmail.com',
//    'role': 'Developer'
//  }

Getting expiry date #

To get the expiry date of the given token pass the token in the function getExpiryDate(). Note: The return value from this function is nullable.

import 'package:jwt_decode/jwt_decode.dart';

String token = 'eyJ0eXAiOiJKV1QiLCJhbGciOiJIUzI1NiJ9.eyJpc3MiOiJKV1QgRGVjb2RlIiwiaWF0IjoxNjA4NTgxNzczLCJleHAiOjE2NDAxMTc3NzMsImF1ZCI6Ind3dy5qd3RkZWNvZGUuY29tIiwic3ViIjoiQSBzYW1wbGUgSldUIiwibmFtZSI6IlZhcnVuIFMgQXRocmV5YSIsImVtYWlsIjoidmFydW4uc2F0aHJleWFAZ21haWwuY29tIiwicm9sZSI6IkRldmVsb3BlciJ9.vXE9ogUeMMsOTz2XQYHxE2hihVKyyxrhi_qfhJXamPQ';

DateTime? expiryDate = Jwt.getExpiryDate(token);

print(expiryDate);

// The expiry date would look like:
// expiryDate = 2021-12-22 01:46:13.000

Checking weather the token has expired or not #

To check weather the token has expired or not pass the token in the function isExpired().
