Chat with website visitors, integrate your favorite tools, and deliver a great customer experience. On **mobile**, the plugin uses the official Crisp Android and iOS SDKs. On **Web and desktop**, it uses the official Crisp Web Chat SDK (embedded chatbox or desktop WebView). The same Dart API covers session data, events, and REST helpers where supported.

Full API differences: [Supported platforms](https://alamin-karno.github.io/flutter-crisp-chat/getting_started/supported_platforms.html) in the docs.

## Installation

### 1. Add Crisp dependency
---

First, add `crisp_chat` as a [dependency in your pubspec.yaml file](https://flutter.dev/using-packages/).

To use the Flutter Crisp Chat, simply import the `crisp_chat` package:

Run this on your project terminal:

```yaml
flutter pub add crisp_chat
```

or manually configure pubspec.yml file

```yaml
dependencies:
  flutter:
    sdk: flutter
  crisp_chat: ^2.7.0
```

**Web / desktop:** No native Crisp SDK install. Web loads `client.crisp.chat` at runtime. Desktop uses an embedded WebView (`desktop_webview_window`) or opens your browser if WebView is unavailable. See [Supported platforms](https://alamin-karno.github.io/flutter-crisp-chat/getting_started/supported_platforms.html) in the docs.

### 2. Setup platform specific settings
---

#### iOS and Android

Configure permissions and push as below. **Web and desktop** only need a valid `websiteID` unless you use REST unread helpers (prefer a backend proxy on web).

#### iOS

Add three rows to the `ios/Runner/Info.plist`:

* key `Privacy - Camera Usage Description` and a usage description.
* key `Privacy - Photo Library Additions Usage Description` and a usage description.
* key `Privacy - Microphone Usage Description` and a usage description.

If editing `Info.plist` as text, add:

```html
<key>NSCameraUsageDescription</key>
<string>your usage description here</string>
<key>NSPhotoLibraryAddUsageDescription</key>
<string>your usage description here</string>
<key>NSMicrophoneUsageDescription</key>
<string>your usage description here</string>
```

**Optional — video/audio calls (iOS only):** **CocoaPods:** `$CrispChatWebRTC = true` in `ios/Podfile`, then `pod install`. **SPM (Flutter 3.44+ default):** `CRISP_CHAT_WEBRTC=true flutter build ios`. Adds ~10 MB. Android native video is not supported yet by Crisp. See [Platform setup — Enable video calls](https://alamin-karno.github.io/flutter-crisp-chat/getting_started/platform_setup.html#enable-video-calls-ios-only).

#### Android

Add Internet permission on `AndroidManifest.xml` in your `android/app/src/main/AndroidManifest.xml` file.

```html
<uses-permission android:name="android.permission.INTERNET"/>
```

Change the minimum Compile SDK version to 35 (or higher) in your `android/app/build.gradle` file.

```groovy
compileSdkVersion 36
```

Change the minimum Android SDK version to 21 (or higher) in your `android/app/build.gradle` file.

```groovy
minSdkVersion 23
```
---
##### *(Optional)* Add Crisp authority and path to your FileProvider in `AndroidManifest.xml` (If your app declares a FileProvider in its AndroidManifest.xml)

```html
<provider android:name="androidx.core.content.FileProvider"
  android:authorities="${applicationId}.fileprovider;${applicationId}.im.crisp.client.uploadfileprovider"
  android:exported="false"
  android:grantUriPermissions="true"
  tools:replace="android:authorities">
  <meta-data android:name="android.support.FILE_PROVIDER_PATHS" 
    android:resource="@xml/file_paths"
    tools:replace="android:resource" />
</provider>
```

and `res/xml/file_paths.xml` add this

```html
<files-path name="crisp_sdk_attachments" path="im.crisp.client/attachments/" />
```

#### Web

No native SDK install. The plugin loads `https://client.crisp.chat/l.js` when you call `openCrispChat`.

1. Enable Web if needed: `flutter create . --platforms=web`
2. Use your real **Website ID** from the [Crisp Dashboard](https://app.crisp.chat/)
3. **Identity verification:** only pass `User.signature` when it is a real HMAC-SHA256 hex string from your server (32+ hex characters). Placeholder values can leave the chat stuck on the loading skeleton.
4. If you use a **Content-Security-Policy**, allow `https://client.crisp.chat` and `https://*.crisp.chat`
5. For REST unread helpers on Web, do not ship API secrets in the client — use a **backend proxy** in production

Run the example:

```bash
cd example && flutter run -d chrome --dart-define=websiteId=YOUR_WEBSITE_ID
```

#### Desktop (macOS, Windows, Linux)

Uses the same Crisp Web Chat SDK in an embedded window (`desktop_webview_window`), or opens the system browser if WebView is unavailable.

1. Enable desktop targets: `flutter create . --platforms=macos,windows,linux`
2. Add the title-bar helper to `main()` **before** `runApp` (required for embedded WebView):

```dart
import 'package:desktop_webview_window/desktop_webview_window.dart';
import 'package:flutter/foundation.dart';

Future<void> main(List<String> args) async {
  WidgetsFlutterBinding.ensureInitialized();
  if (!kIsWeb &&
      (defaultTargetPlatform == TargetPlatform.macOS ||
          defaultTargetPlatform == TargetPlatform.windows ||
          defaultTargetPlatform == TargetPlatform.linux)) {
    if (runWebViewTitleBarWidget(args)) return;
  }
  runApp(const MyApp());
}
```

3. **macOS (sandbox):** add outgoing network client to `macos/Runner/DebugProfile.entitlements` and `Release.entitlements`:

```xml
<key>com.apple.security.network.client</key>
<true/>
```

4. **Windows:** install [WebView2 Runtime](https://developer.microsoft.com/microsoft-edge/webview2/)
5. **Linux:** `sudo apt install libwebkit2gtk-4.1-dev`

`openChatboxFromNotification`, `setOnNotificationTappedCallback`, `onCrispEvent`, and `CrispConfig.enableNotifications` do **not** apply on Web/desktop.

See [Supported platforms](https://alamin-karno.github.io/flutter-crisp-chat/getting_started/supported_platforms.html) for the API matrix and troubleshooting.

### 3. Configure your app to receive Crisp notifications (Android & iOS only)
---

> **Note:** Sections 3–ix below are for **mobile push notifications** only. Web and desktop do not use FCM/APNs through this plugin.

#### i). Create a Firebase project and add it to your Flutter project

- In order to complete this step, follow the Firebase [Get started](https://firebase.google.com/docs/android/setup) guide.

- At the end of it, also add the following dependency to your project.
  ```yaml
  flutter pub add firebase_core
  flutter pub add firebase_messaging
  ```

#### ii). Enable Push notifications in Crisp dashboard for your Android app

- Go to your Firebase **Project settings**,
- Go to the **Cloud Messaging** tab,
- In the Firebase **Cloud Messaging API (V1)** section, copy your **Sender ID (1)**, you will need it later.

![Copy your Firebase Cloud Messaging Sender ID](https://github.com/user-attachments/assets/778fcfdd-a9ad-465b-b425-a0b45bf5f0eb)

- Copy your Firebase Cloud Messaging **Sender ID**
- Go to the **Service accounts** tab,
- In the **Firebase Admin SDK** section, click on the **Generate new private key (2)** button and save it for later.
  
![Generate and download your Firebase Admin private key](https://github.com/user-attachments/assets/99d7faf3-c1db-41b4-afc9-4bbd64bec1f7)

- Generate and download your Firebase Admin private key
- Go to your **[Crisp Dashboard](https://app.crisp.chat/)**,
- Select your Workspace,
- Go to **Settings** > **ChatBox Settings** > **Push Notifications**,
- Under the **Firebase Cloud Messaging** section :
    - Enable the **Notify users using Android (3)** option,
    - Paste the **Sender ID** you have copied previously into the **Project ID (4)** field,
    - Select or drag your **Firebase Admin private key** file you have downloaded earlier in the **Certificate (5)** box,
    - Click on the Verify **Credentials (6)** button.
  
![Enable Push Notifications in Crisp dashboard](https://github.com/user-attachments/assets/1fe0225e-4a1b-49bd-8814-c4d662fbf703)

- Crisp will notify you that it is checking FCM Credentials in order to send notifications to your users.
  
![Crisp checking FCM Credentials](https://github.com/user-attachments/assets/66623e73-3b92-4c79-b6ed-9db696ff1bd9)

- Finally, if FCM Credentials are valid, Crisp will update the Push Notifications status to **live**.

#### iii). Handle Push notifications in your Android app

You have two options for handling Crisp push notifications:

##### Option A: Auto-open ChatActivity (Crisp only)

Declare the Crisp `CrispNotificationService` in the `<application>` tag of your `AndroidManifest.xml`.

```xml
<service
    android:name="im.crisp.client.external.notification.CrispNotificationService"
    android:exported="false">
    <intent-filter>
      <action android:name="com.google.firebase.MESSAGING_EVENT" />
    </intent-filter>
</service>
```

Notifications will be handled by **Crisp** `CrispNotificationService` and a tap on it will launch your `MainActivity` and **automatically open** the Crisp `ChatActivity` with the corresponding session.

##### Option B: Open app first, then chatbox (recommended)

If you want your app to open first (so the user sees your app UI) and then open the Crisp chatbox programmatically, use the SDK's `CrispChatNotificationService` instead:

```xml
<service
    android:name="com.alaminkarno.flutter_crisp_chat.CrispChatNotificationService"
    android:exported="false">
    <intent-filter>
      <action android:name="com.google.firebase.MESSAGING_EVENT" />
    </intent-filter>
</service>
```

Then in your Flutter code, handle the notification tap to open the chatbox:

```dart
@override
void initState() {
  super.initState();

// Handle app launched from a Crisp notification (terminated state)
  FlutterCrispChat.openChatboxFromNotification();

// Handle notification tap while app is in the background
  FlutterCrispChat.setOnNotificationTappedCallback(() {
    FlutterCrispChat.openChatboxFromNotification();
  });
}
```

- `openChatboxFromNotification()` — Checks if the app was launched from a Crisp notification and opens the chatbox. Returns `true` if successful, `false` otherwise.
- `setOnNotificationTappedCallback(callback)` — Sets a callback that fires when a Crisp notification is tapped while the app is already running in the background.

#### iv). Customize Push notifications for android app

Crisp Push notifications customizable in 3 ways: color, icon and sound.

For the first two, you can update them from your `AndroidManifest.xml` as you would do with Firebase.

```xml
  <application>
    <meta-data
      android:name="com.google.firebase.messaging.default_notification_icon"
      android:resource="@drawable/my_notification_icon"
      tools:replace="android:resource" />
    <meta-data
      android:name="com.google.firebase.messaging.default_notification_color"
      android:resource="@color/my_notification_color"
      tools:replace="android:resource" />
  </application>
```

For the sound, you can add a `raw` resource named `crisp_chat_message_receive` to your app which will be played upon notification receipt.

#### v). Enable Push notifications in Crisp dashboard for your iOS app

- Create an **APNs-enabled** private key in your Apple Developer account. See the [Apple documentation](https://developer.apple.com/help/account/manage-keys/create-a-private-key/) for detailed instructions.
- Upload your key and configure push notifications in the Crisp web app at **Settings** > **Chatbox Settings** > **Push Notifications**.
- Add the **“Push Notifications”** capability to your app:
    - Open your project in **Xcode**
    - Select your target
    - Go to the **“Signing & Capabilities”** tab
    - Click the **“+”** button and add **“Push Notifications”**
 
![Push Notifications](https://github.com/user-attachments/assets/8581c872-f836-45f6-9a8c-7a5c5a998cea)

#### vi). 🔔 iOS Push Notification Setup

To enable Crisp push notifications on iOS, **you must register for remote notifications in your app's `AppDelegate.swift`**.

➡️ **Step: Add the following inside `didFinishLaunchingWithOptions`**:

```swift
DispatchQueue.main.async {
    UIApplication.shared.registerForRemoteNotifications()
}
```
- Important
    - `Currently, push notifications are only sent to production APNs channels. Notifications will not be received when testing with development provisioning profiles or in sandbox mode. This limitation will be resolved in a future update.`

#### vii). Ensure Firebase initialization in your Flutter project

```dart
import 'package:firebase_core/firebase_core.dart';

import 'firebase_options.dart';

Future<void> main() async {
  WidgetsFlutterBinding.ensureInitialized();
  await Firebase.initializeApp(
    options: DefaultFirebaseOptions.currentPlatform,
  );
  runApp(const MyApp());
}
```

#### viii). Request permission to receive messages

On iOS, and Android 13 (or newer), before FCM payloads can be received on your device, you must first ask the user's permission.

```dart
FirebaseMessaging messaging = FirebaseMessaging.instance;

NotificationSettings settings = await messaging.requestPermission(
  alert: true,
  announcement: false,
  badge: true,
  carPlay: false,
  criticalAlert: false,
  provisional: false,
  sound: true,
);

print('User granted permission: ${settings.authorizationStatus}');
```

#### ix). Background messages

The process of handling background messages is different on native Android and Apple platforms.

There are a few things to keep in mind about your background message handler:

- It must not be an anonymous function.
- It must be a top-level function (e.g. not a class method which requires initialization).
- When using Flutter version 3.3.0 or higher, the message handler must be annotated with `@pragma('vm:entry-point')` right above the function declaration (otherwise it may be removed during tree shaking for release mode).

```dart
import 'package:firebase_core/firebase_core.dart';
import 'package:firebase_messaging/firebase_messaging.dart';

import 'firebase_options.dart';

@pragma('vm:entry-point')
Future<void> _firebaseMessagingBackgroundHandler(RemoteMessage message) async {
  // If you're going to use other Firebase services in the background, such as Firestore,
  // make sure you call `initializeApp` before using other Firebase services.
  await Firebase.initializeApp();

print("Handling a background message: ${message.messageId}");
}

Future<void> main() async {
  WidgetsFlutterBinding.ensureInitialized();
  await Firebase.initializeApp(
    options: DefaultFirebaseOptions.currentPlatform,
  );
  FirebaseMessaging.onBackgroundMessage(_firebaseMessagingBackgroundHandler);
  runApp(const MyApp());
}
```

### 4. Get your Website ID:
---
Go to your [Crisp Dashboard](https://app.crisp.chat/), and copy your Website ID:

![Crisp Dashboard](https://github.com/user-attachments/assets/ef6b9932-8141-4108-8f11-f5f3b40cbe15)

- **Android / iOS:** disable **Lock the chatbox to website domain (and subdomains)** under **Settings** → **Website Settings** → **Chatbox & Email Settings** → **Chatbox Security**. With domain lock enabled, chat fails with **"Error starting chat"** even when the Website ID is valid. See [docs — Chatbox Security](https://alamin-karno.github.io/flutter-crisp-chat/core_feature/configuration.html#crisp-dashboard-chatbox-security).

### 5. Setup your flutter app to use Crisp
---

Here's a more detailed example of how to configure CrispConfig and use the plugin methods. To open ChatView for crisp, use the `openCrispChat` method of the `FlutterCrispChat` class:

```dart
import 'package:flutter/material.dart';
import 'package:crisp_chat/crisp_chat.dart';
import 'package:flutter/foundation.dart'; // For kDebugMode

class CrispChatPage extends StatefulWidget {
  const CrispChatPage({super.key});

@override
  State<CrispChatPage> createState() => _CrispChatPageState();
}

class _CrispChatPageState extends State<CrispChatPage> {
  final String websiteID = 'YOUR_WEBSITE_ID'; // Replace with your actual Website ID
  final String identifier = 'YOUR_CRISP_API_IDENTIFIER'; // Replace with your actual Crisp API Identifier
  final String crispApiKey = 'YOUR_CRISP_API_KEY'; // Replace with your actual Crisp API Key
  int count = 0;
  
  late CrispConfig _crispConfig;

@override
  void initState() {
    super.initState();

// Handle Crisp notification tap (Option B only - see section 3.iii)
    // Opens the chatbox if the app was launched from a Crisp notification (terminated state)
    FlutterCrispChat.openChatboxFromNotification();

// Listen for Crisp notification taps while the app is in the background
    FlutterCrispChat.setOnNotificationTappedCallback(() {
      FlutterCrispChat.openChatboxFromNotification();
    });

// Configure Crisp User (Optional)
    // All user fields are optional. Only provide what you have.
    final crispUser = User(
      email: "user@example.com",
      signature: "USER_EMAIL_HMAC_SHA256_SIGNATURE",
      nickName: "John Doe",
      phone: "1234567890", 
      avatar: "https://example.com/avatar.png", 
      company: Company(
        name: "Example Corp",
        url: "https://example.com", 
        companyDescription: "A sample company providing excellent services.",
        employment: Employment(title: "Lead Developer", role: "Software Engineer"),
        geoLocation: GeoLocation(city: "New York", country: "USA"),
      ),
    );

// 1. Initialize CrispConfig with all desired parameters.
    _crispConfig = CrispConfig(
      websiteID: websiteID, // [required] Your Crisp website ID.
      tokenId: "your_user_token_id_optional", // Optional: Assign a unique token to this session.
      sessionSegment: "beta_testers", // Optional: Assign a segment to categorize users (e.g., "premium", "trial").
      user: crispUser, // Optional: Provide user details.
      enableNotifications: true, // Optional: Enable or disable push notifications. Defaults to true.
      modalPresentationStyle: ModalPresentationStyle.fullScreen, // Optional: iOS modal presentation style. Defaults to fullScreen.
    );

// 2. Optionally, set additional session data *before* opening the chat.
    // This data is associated with the session when it's created or next resumed.
    // Useful for sending custom attributes that might not fit into the User object.
    FlutterCrispChat.setSessionString(key: "custom_data_point", value: "some_important_value");
    FlutterCrispChat.setSessionInt(key: "user_score", value: 120);
    FlutterCrispChat.setSessionSegments(segments: ["registered_user", "newsletter_subscriber"], overwrite: false);
  }

void _openChat() async {
    // 3. Open the Crisp Chat UI using the prepared configuration.
    await FlutterCrispChat.openCrispChat(config: _crispConfig);

// 4. Optionally, retrieve the session identifier after the chat is opened.
    // This can be useful for logging or internal tracking.
    String? sessionId = await FlutterCrispChat.getSessionIdentifier();
    if (sessionId != null) {
      if (kDebugMode) {
        print('Crisp Session ID: $sessionId');
      }
    } else {
      if (kDebugMode) {
        print('No active Crisp session found or an error occurred while retrieving the ID.');
      }
    }
  }

void _resetSession() async {
    // Call resetCrispChatSession, for example, when your app user logs out.
    // This is crucial for privacy and ensuring that the next user (or a guest)
    // does not see or interact with the previous user's chat history and data
    // within the Crisp SDK session on the device.
    await FlutterCrispChat.resetCrispChatSession();
    if (kDebugMode) {
      print('Crisp session has been reset. The previous user\'s data is cleared from the local SDK session.');
    }
  }

void _checkUnreadMessages() async {
    // Call getUnreadMessageCount to check for unread messages.
    int? unreadCount = await FlutterCrispChat.getUnreadMessageCount(
      websiteId: websiteID,
      identifier: identifier,
      key: crispApiKey,
    );

if (unreadCount != null && unreadCount > 0) {
      if (kDebugMode) {
        print('You have $unreadCount unread messages.');
      }
      setState(() {
        count = unreadCount;
      });
    }
  }

@override
  Widget build(BuildContext context) {
    return Scaffold(
      appBar: AppBar(
        title: const Text('Crisp Chat Example'),
      ),
      body: Center(
        child: Column(
          mainAxisAlignment: MainAxisAlignment.center,
          children: <Widget>[
            ElevatedButton(
              onPressed: _openChat,
              child: const Text('Open Crisp Chat (Full Config)'),
            ),
            const SizedBox(height: 20),
            ElevatedButton(
              onPressed: _resetSession,
              child: const Text('Reset Crisp Session'),
            ),
            const SizedBox(height: 20),
            Badge.count(
              count: count,
              isLabelVisible: count != 0,
              maxCount: 9,
              child: ElevatedButton(
                onPressed: _checkUnreadMessages,
                child: Text('Unread'),
              ),
            )
          ],
        ),
      ),
    );
  }
}
```

To use this code, replace `YOUR_WEBSITE_ID` with your own website ID from the Crisp dashboard. The example demonstrates initializing `CrispConfig` with detailed user and company information, setting additional session data, opening the chat interface, retrieving the session ID, and resetting the session.

### iOS Modal Presentation Styles

The `modalPresentationStyle` parameter in `CrispConfig` allows you to control how the Crisp chat view is presented on iOS devices. This is particularly important for preventing touch events from passing through to the underlying Flutter UI.

#### Available Modal Presentation Styles:

- **`ModalPresentationStyle.fullScreen`** (Default) - The view controller covers the entire screen. This prevents touch events from passing through to the underlying UI.
- **`ModalPresentationStyle.pageSheet`** - The view controller is displayed as a page sheet with a dimmed background.
- **`ModalPresentationStyle.formSheet`** - The view controller is displayed as a form sheet, centered on the screen.
- **`ModalPresentationStyle.overFullScreen`** - The view controller covers the screen but allows underlying content to show through.
- **`ModalPresentationStyle.overCurrentContext`** - The view controller is displayed over the parent view controller's content.
- **`ModalPresentationStyle.popover`** - Popover on iPad (centered); on iPhone UIKit adapts to full screen.

#### Example Usage:

```dart
// Using pageSheet presentation style
final config = CrispConfig(
  websiteID: 'YOUR_WEBSITE_ID',
  modalPresentationStyle: ModalPresentationStyle.pageSheet,
);

// Using formSheet presentation style
final formSheetConfig = CrispConfig(
  websiteID: 'YOUR_WEBSITE_ID',
  modalPresentationStyle: ModalPresentationStyle.formSheet,
);
```

**Note:** This parameter is iOS-specific and will only affect iOS devices. On Android, the chat will always use the platform's default presentation behavior. On **Web and desktop**, it is ignored.

### iOS video and audio calls (optional)

Crisp video/audio calls are **iOS-only** and **opt-in at build time** (not a `CrispConfig` flag). Default builds use the standard `Crisp` SDK without calls.

| Build system  | Enable video                                                   |
|---------------|----------------------------------------------------------------|
| **CocoaPods** | `$CrispChatWebRTC = true` in `ios/Podfile`, then `pod install` |
| **SPM**       | `CRISP_CHAT_WEBRTC=true flutter build ios`                     |

Check at runtime:

```dart
final supported = await FlutterCrispChat.isVideoCallsSupported();
// true on iOS WebRTC builds, Web, and desktop; false on Android and default iOS builds
```

Adds ~10 MB to the iOS binary. Android native video is [not supported yet by Crisp](https://github.com/crisp-im/crisp-sdk-android/issues/181). Full setup: [Enable video calls (iOS only)](https://alamin-karno.github.io/flutter-crisp-chat/getting_started/platform_setup.html#enable-video-calls-ios-only).

### Helpdesk / FAQ

Open the Crisp Helpdesk/FAQ interface directly without going through the live chat. Useful when you want to direct users to self-service help content.

> **Platform support:** All platforms — Android, iOS, Web, macOS, Windows, and Linux. Android/iOS use the native SDK; Web and desktop use the Crisp Web Chat SDK (`$crisp.push`).

#### Open the helpdesk search screen

```dart
await FlutterCrispChat.openHelpdesk(websiteId: 'YOUR_WEBSITE_ID');
```

#### Open a specific helpdesk article

```dart
await FlutterCrispChat.openHelpdeskArticle(
  websiteId: 'YOUR_WEBSITE_ID',
  locale: 'en',               // article language code
  slug: 'article-slug',       // article slug from your Crisp Helpdesk dashboard
  title: 'Optional title',    // optional
  category: 'Optional cat',   // optional
);
```

The `slug` for an article can be found in the Crisp dashboard under **Helpdesk** → open the article → the URL contains the slug. Both methods throw `ArgumentError` if required fields are empty.

For every request that you make to `getUnreadMessageCount` or `markMessagesAsRead`, you must submit your authentication token (`identifier` and `key`), as well as your `website_id`.

::: tip iOS unread count
On iOS, `unread.visitor` may not reset after reading chat in the native SDK. Call `FlutterCrispChat.markMessagesAsRead()` after the visitor closes chat. See [docs/unread-count-verification.md](docs/unread-count-verification.md).
:::

**Obtaining `Identifier` & `Key`:**

1. Head over to the [Crisp Marketplace](https://marketplace.crisp.chat/)
2. Sign in or create an account (this account is different from your main Crisp account)
3. Once logged-in, go to **Plugins** and click on the **New Plugin button**
4. Select the plugin type, in this case Private
5. Name your plugin a name, eg. "My First Crisp Plugin", and hit **Create**
6. On the plugin tab, go to **Tokens** and scroll down to **Development Token** to view (and manage) your token `identifier`/`key` pair 
7. Obtaining a production token is the next natural step once you are ready to step into production with your plugin or if your usage requires higher quotas.

Before using your development token, you now need to associate your marketplace account to your Crisp workspace. This is done by specifying a **Trusted Workspace**:

1. Go to the **Settings** of your **Crisp Marketplace** account
2. Click on **Add Trusted Workspace** and submit your `website_id`
3. Enter the credentials of your main Crisp account (the ones you use to access your main Crisp account) and then submit your 2FA token (if any is enabled)
4. You're all done! You are now ready to use REST API and start building your plugin

### Chat Events

Listen to native Crisp SDK events — useful for updating an unread badge in real time instead of polling `getUnreadMessageCount()`.

> **Platform support:** Android and iOS only. The stream never emits on Web/desktop.

```dart
final subscription = FlutterCrispChat.onCrispEvent.listen((event) {
  switch (event.type) {
    case CrispEventType.sessionLoaded:
      print('Session loaded: ${event.sessionId}');
    case CrispEventType.chatOpened:
      print('Chat opened');
    case CrispEventType.chatClosed:
      print('Chat closed');
    case CrispEventType.messageSent:
    case CrispEventType.messageReceived:
      print('Message from ${event.message?.from}: ${event.message?.text}');
    case CrispEventType.notificationReceived:
      print('Notification data: ${event.notificationData}'); // Android-only
  }
});

// Later, when no longer needed:
await subscription.cancel();
```

The native event callback is registered on the first `.listen()` call and unregistered once the last listener cancels, so it's safe to listen and cancel freely.

`CrispMessage` (carried by `messageSent`/`messageReceived` events) is a minimal summary — `isMe`, `from`, `origin`, `timestamp`, `fingerprint`, `contentType`, and `text` (only populated when `contentType` is `CrispMessageContentType.text`). Rich content (carousel targets, picker choices, file/audio metadata) is not mapped in this version.

`CrispEventType.notificationReceived` is Android-only — the iOS Crisp SDK has no matching callback, so iOS never emits it.
