🔑 Getting Your Widget Key

Every widget below needs a widgetKey from your MySampark account:

1. Sign up / log in at mysampark.com (dashboard: socialadmin.mysampark.com).
2. Open the Chatbot section of your dashboard and create (or select) a widget.
3. Copy its Widget Key (starts with pk_) — this is public and safe to embed in your app, same as the data-key used in the website embed script.
4. The widget also has a Widget Secret (starts with sk_) — used only for identifying logged-in users (see below). Never put this in your Flutter app's source. It belongs on your own backend.

Exact menu labels may differ slightly as the dashboard evolves — if a step above doesn't match what you see, the Chatbot → Widgets area is the place to look.

Identifying logged-in users (optional)

If you want returning/logged-in users to skip the pre-chat survey and be recognized automatically, your own backend (not the Flutter app) computes a verification hash for the current user and sends it to the app:

// your_backend — an authenticated endpoint, e.g. POST /me/chat-hash
return hash_hmac('sha256', $user->id, env('MYSAMPARK_WIDGET_SECRET'));

Then pass the result as userHash (see Usage below). Anonymous visitors can skip userId/userHash entirely.

📱 Platform Setup

Android Setup

To allow links (URLs) in chat messages to open in external browsers on Android 11+ (API Level 30+), add the following <queries> configuration inside <manifest> in your app's android/app/src/main/AndroidManifest.xml:

<manifest xmlns:android="http://schemas.android.com/apk/res/android">
    <queries>
        <intent>
            <action android:name="android.intent.action.VIEW" />
            <data android:scheme="https" />
        </intent>
        <intent>
            <action android:name="android.intent.action.VIEW" />
            <data android:scheme="http" />
        </intent>
    </queries>
</manifest>

🔧 Usage

Option A — Floating Bubble (Recommended)

Drop it as your Scaffold's floatingActionButton and it renders a branded chat bubble:

import 'package:mysampark_chat/mysampark_chat.dart';

Scaffold(
  body: YourAppBody(),
  floatingActionButton: MySamparkChatBubble(
    widgetKey: 'YOUR_WIDGET_KEY',   // from MySampark dashboard

    // ── Optional: User identity parameters ───────────────────────────
    userId:    currentUser.id,
    userHash:  currentUser.chatHash,  // Verification hash from your backend
    userName:  currentUser.name,
    userEmail: currentUser.email,
    // ───────────────────────────────────────────────────────────────────
  ),
);

Option B — Full Screen Chat Page

Navigator.push(
  context,
  MaterialPageRoute(
    builder: (_) => MySamparkChatScreen(
      widgetKey: 'YOUR_WIDGET_KEY',

      // Optional: User identity parameters
      userId:    currentUser.id,
      userHash:  currentUser.chatHash,
      userName:  currentUser.name,
      userEmail: currentUser.email,
    ),
  ),
);

Option C — Anonymous Visitor (No login required)

// Just the widgetKey — everything else is optional
MySamparkChatBubble(widgetKey: 'YOUR_WIDGET_KEY');

🏠 Home Tab, Offers & Order Tracking

MySamparkChatScreen opens on a Home tab by default — a greeting header plus up to three cards:

Card	Shown when	What it does
Offers	Admin has show_offers on + an offers source connected	Fetches GET /api/chatbot/offers, shows a bottom sheet of live deals with tap-to-copy discount codes
Chat with us	Always	Switches to the normal chat conversation view
Track your order	Admin has show_order_tracking on + an order source connected	Opens a form (order number + email — email is skipped for HMAC-identified users), calls POST /api/chatbot/track-order, and shows status / carrier / tracking link

This is entirely admin-controlled — nothing to configure in Flutter. If a merchant hasn't enabled Offers or Order Tracking in the dashboard, those cards simply don't render and only "Chat with us" is shown.

The header back arrow (and the Android hardware back button) returns from the Chat view to Home instead of closing the screen; closing the screen itself is the ✕ button on the Home header.
