Installation #

1. Add Crisp dependency #

First, add crisp_chat as a dependency in your pubspec.yaml file.

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

Run this on your project terminal:

flutter pub add crisp_chat

or manually configure pubspec.yml file

dependencies:
  flutter:
    sdk: flutter
  crisp_chat: ^2.2.1

2. Setup platform specific settings #

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:

<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>

Android

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

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

Change the minimum Compile SDK version to 34 (or higher) in your android/app/build.gradle file.

compileSdkVersion 34

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

minSdkVersion 21

(Optional) Add Crisp authority and path to your FileProvider in `AndroidManifest.xml` (If your app declares a FileProvider in its AndroidManifest.xml)

<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

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

3. Configure your app to receive Crisp notifications #

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

In order to complete this step, follow the Firebase Get started guide.
At the end of it, also add the following dependency to your project.
```
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

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

Generate and download your Firebase Admin private key
Go to your Crisp Dashboard,
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

Crisp will notify you that it is checking FCM Credentials in order to send notifications to your users.

Crisp checking FCM Credentials

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

iii). Handle Push notifications in your Android app

You just have to declare our CrispNotificationService in the application tag of your AndroidManifest.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 open Crisp ChatActivity with the corresponding session.

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.

  <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 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

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.

vi). Ensure Firebase initialization in your Flutter project

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());
}

vii). 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.

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}');

viii). 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).

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, and copy your Website ID:

Crisp Dashboard

5. Setup your flutter app to use Crisp #

To open ChatView for crisp, use the openCrispChat method of the FlutterCrispChat class:

First Imported Package:

import 'package:crisp_chat/crisp_chat.dart';

Then:

 final String websiteID = 'YOUR_WEBSITE_KEY';
 late CrispConfig config;

   @override
  void initState() {
    super.initState();
    config = CrispConfig(
      websiteID: websiteID,
    );
  }

  @override
 Widget build(BuildContext context) {
   return MaterialApp(
     debugShowCheckedModeBanner: false,
     home: Scaffold(
       appBar: AppBar(
         title: const Text('Crisp Chat'),
       ),
       body: Center(
         child: Column(
           mainAxisAlignment: MainAxisAlignment.center,
           crossAxisAlignment: CrossAxisAlignment.center,
           children: [
             ElevatedButton(
               onPressed: () async {
                 await FlutterCrispChat.openCrispChat(config: config);
                 FlutterCrispChat.setSessionString(
                   key: "a_string",
                   value: "Crisp Chat",
                 );
                 FlutterCrispChat.setSessionInt(
                   key: "a_number",
                   value: 12345,
                 );

                 /// Checking session ID After 5 sec
                 await Future.delayed(const Duration(seconds: 5), () async {
                   String? sessionId =
                   await FlutterCrispChat.getSessionIdentifier();
                   if (sessionId != null) {
                     if (kDebugMode) {
                       print('Session ID: $sessionId');
                     }
                   } else {
                     if (kDebugMode) {
                       print('No active session found!');
                     }
                   }
                 });
               },
               child: const Text('Open Crisp Chat'),
             ),
             const SizedBox(height: 20),
             ElevatedButton(
               onPressed: () async {
                 await FlutterCrispChat.resetCrispChatSession();
               },
               child: const Text('Reset Chat Session'),
             ),
           ],
         ),
       ),
     ),
   );
 }

To use this code, you will need to provide your own Crisp website ID. You can do this by replacing YOUR_WEBSITE_KEY with your own website ID. Once you have done this, you can run the app and press the "Open Crisp Chat" button to launch the chat window. You can add more information using CrispConfig.
