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 = {
