  • Performs login by redirecting user to an identity server's authorize endpoint
  • Performs logout by redirecting user to an identity server's end session endpoint
  • Periodically renews access/ID tokens in the background using iframe


This package is usually used together with an idle tracking library/package such as idle_tracker.

import 'package:silent_auth/silent_auth.dart';
import 'package:idle_tracker/idle_tracker.dart';

final silentAuth = new SilentAuth(
    baseIdentityUri: '',
    clientId: 'admin',
    scope: 'openid api',
    redirectUri: 'http://localhost:12345/index.html'
    silentRedirectUri: 'http://localhost:12345/silent_auth.html',
    onRenew: (auth) => requestHeaders['Authorization'] = 'Bearer ${auth.accessToken}');

// Request headers for making API calls.
final requestHeaders = {
  'Accept': 'application/json',
  'Content-Type': 'application/json; charset=UTF-8',
void logIn() {
  // Pre-login tasks may be done here.

void logOut() {
    // Pre-logout tasks may be done here.

void loadData() {
    // Make some API call using [requestHeaders].
void main() {
  // Initializes silent authentication.
  // If the access token doesn't exist or has expired, redirect user to the login page.
  if (!silentAuth.isAccessTokenValid) {
  // Set up an idle tracker to automatically log the user out after 30
  // minutes of inactivity.
  new IdleTracker(
      timeout: const Duration(minutes: 30),
      startsAsIdle: true,
      onIdle: logOut)

Features and bugs

Please file feature requests and bugs at the issue tracker.



  • Fixed a bug that happens when logOut is called due to the new Token type


  • refactoring: utils.dart was moved to /lib and no longer contains functions used internally
  • Added class Token, which represents an access or ID token
  • BREAKING CHANGE: SilentAuth.accessToken and SilentAuth.idToken are now of type Token rather than String.


  • Fixed a bug in which the token renewal is not properly scheduled the first time


  • Fixed a bug causing post_logout_redirect_uri not to be displayed in the logged-out page


  • Fixed a bug causing utils.callEndpoint to fail when compiled to JS
