keycloak_adapter 0.0.3

This project contains Keycloak Js Adapter

Keycloak JS adapter

A Flutter package that bundles the official Keycloak JavaScript adapter (keycloak.js) as an asset.
This makes it easy to integrate Keycloak into Flutter Web apps without relying on an external CDN or changing your CI pipeline.

---

Features

• Ships keycloak.js directly inside the package assets.
• Can be loaded in your web/index.html or a custom script.js.
• Ensures reproducible builds: the asset is versioned together with the package.
• Works with Flutter Web out of the box.

---

Installation

Add the dependency to your pubspec.yaml:

dependencies:
  keycloak_adapter : ^0.0.1

Run:

flutter pub get

---

Asset Path

After a Flutter Web build, the file is served automatically at:

/assets/packages/keycloak_adapter/assets/js/keycloak.js

---

Usage

1. Include in index.html

Inside your web/index.html, add:

<script src="/assets/packages/my_keycloak_pkg/assets/js/keycloak.js"></script>

This ensures the Keycloak client is available globally as Keycloak.

2. Load and configure in script.js

(async () => {
  const keycloak = new Keycloak({
    url: "https://auth.example.com",
    realm: "my-realm",
    clientId: "my-client"
  });
 
  try {
    await keycloak.init({ onLoad: "login-required" });
    window.keycloak = keycloak; // expose globally
    console.log("Authenticated:", keycloak.token);
  } catch (err) {
    console.error("Keycloak init failed:", err);
  }
})();

3. Consume from Flutter

In Dart you can call JS interop to access window.keycloak,
or fetch configuration values from your script via window.APP_CONFIG if you export them there.
