jwt_decode

jwt_decode is a lightweight library for decoding JSON Web Tokens (JWTs) in Dart.

IMPORTANT: This library does not validate the tokens. It can decode any well-formed ones.

Installation

Add jwt_decode to your project's pubspec.yaml file:

dependencies:
  jwt_decode: ^0.3.1

Then run flutter pub get to install the package.

Using

Here's an example of how to use jwt_decode to decode a JWT:

import 'package:jwt_decode/jwt_decode.dart';

void main() {
  final String token = 'eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.eyJzdWIiOiIxMjM0NTY3ODkwIiwibmFtZSI6IkpvaG4gRG9lIiwiaWF0IjoxNTE2MjM5MDIyLCJleHAiOjE1MTYyMzkwMjJ9.SflKxwRJSMeKKF2QT4fwpMeJf36POk6yJV_adQssw5c';
  final Map<String, dynamic> decodedToken = Jwt.parseJwt(token);
  print(decodedToken);
}

This will output the following:

{
  "sub": "1234567890",
  "name": "John Doe",
  "iat": 1516239022,
  "exp": 1516239022
}
