applaudiq_embed 1.2.0

Embed the Applaud IQ recognition portal in a Flutter app (Android + iOS) with auto / manual login and native SSO, in a hardened WebView. Mirrors the iOS / Android / React Native / Web SDKs.

Applaud IQ Embed SDK — Flutter

Embed the Applaud IQ recognition portal in a Flutter app (Android and iOS) with auto-login, manual login, and native SSO. The SDK renders the portal in a hardened webview_flutter WebView and mirrors the iOS / Android / React Native / Web SDK bridge protocol.

• Auto + manual login — silent sign-in with a server-minted token, or the portal's own email/SSO login.
• Native SSO — Google / Microsoft via the system browser, returned to your app on your own deep-link scheme.
• Callbacks — onReady / onAuthPending / onError / onClose / onSignOut.

Build integration

1. Install

flutter pub add applaudiq_embed
cd ios && pod install && cd ..   # iOS only

2. Register your SSO callback scheme

SSO opens in the system browser and returns to your app via a deep link. Pick a scheme unique to your app and register it natively; pass the same value as config.ssoCallback (myapp://sso-callback). The SDK sends it to the backend as native_redirect, so the callback returns to exactly your app.

iOS — ios/Runner/Info.plist:

<key>CFBundleURLTypes</key>
<array><dict>
  <key>CFBundleURLSchemes</key>
  <array><string>myapp</string></array>
</dict></array>

Android — android/app/src/main/AndroidManifest.xml, inside <application> (the CallbackActivity ships with flutter_web_auth_2):

<activity
    android:name="com.linusu.flutter_web_auth_2.CallbackActivity"
    android:exported="true">
  <intent-filter android:label="flutter_web_auth_2">
    <action android:name="android.intent.action.VIEW" />
    <category android:name="android.intent.category.DEFAULT" />
    <category android:name="android.intent.category.BROWSABLE" />
    <data android:scheme="myapp" />
  </intent-filter>
</activity>

3. Import

import 'package:applaudiq_embed/applaudiq_embed.dart';

4. Mint a session on your server (auto-login)

For auto-login, your backend exchanges the secret for a one-time token (single-use, ~60s). Manual login skips this entirely.

POST <your-api>/api/v1/embed/sessions
Authorization: Bearer aiq_embed_…          // the SECRET — server-side only
Content-Type: application/json

{ "employee": { "email": "[e-mail]" }, "autoProvision": true }

// 200 OK → { "embedToken": "9f3a…", "expiresIn": 60, "hrPending": false }

5. Present the embed

ApplaudIQEmbed(
  config: EmbedConfig(
    key: 'pk_live_…',                       // publishable key from HR
    baseUrl: 'https://recognize.applaudiq.com',
    ssoCallback: 'myapp://sso-callback',    // your scheme from step 2
  ),
  token: embedToken,            // auto mode only — omit for manual
  mode: ApplaudIQMode.auto,     // .auto | .manual
  onReady: () {},
  onAuthPending: () {},         // signed in, awaiting HR approval
  onError: (msg) {},            // bad key/token OR a failed SSO sign-in
  onClose: () {},
  onSignOut: () {},             // user signed out of an auto embed
)

SSO flow

Tapping Continue with Google / Microsoft opens the system browser (ASWebAuthenticationSession on iOS, Custom Tabs on Android). On success the one-time code returns on myapp://sso-callback?code=… and is exchanged inside the WebView (onReady). On failure (e.g. wrong account) the SDK fires onError(message) and reloads the login so the user can retry.

---

Security model

The SDK applies the same WebView hardening as the iOS and Android SDKs:

• The WebView is pinned to the portal origin. Only baseUrl loads in the main frame; off-origin top-level links open in the system browser instead (url_launcher), so an open-redirect can't move the authenticated session onto another page. Sub-frames (reCAPTCHA, fonts, analytics) still load in place.
• The native bridge runs only on the portal origin. The postMessage bridge and the window.__APPLAUDIQ_EMBED__ flag install only when the page is the portal.
• Only the portal can drive the bridge. Every incoming message is checked against the WebView's current origin (controller.currentUrl()) before it is processed.
• SSO runs in the system browser, not the WebView — Google/Microsoft reject WebView OAuth; the one-time code is exchanged inside the WebView (cookies stay in its store).
• The publishable key is browser-safe — only the pk_… key lives in the app; the aiq_embed_… server secret must never be embedded (mint tokens on your backend).
• baseUrl must use HTTPS — a plain-http:// base is rejected with onError('insecure_base_url') and nothing loads, except localhost/127.0.0.1/10.0.2.2 in a debug build.

Platform note: webview_flutter's Dart API doesn't expose every native WebView setting. Mixed-content blocking and file://-URL access controls aren't surfaced by the plugin — the portal is HTTPS-only and the navigation guard + origin checks are the primary defenses; the SDK never loads file:// content.

Downloads & external links

When the portal (or the reward store nested inside it) needs to open a URL outside the WebView — a file download, a payment page, or an OAuth handoff — it sends the applaudiq:open-external bridge message with payload { url }. The SDK opens http(s) URLs in the system browser (url_launcher, LaunchMode.externalApplication). No app code is required.
