Usage #
Initializing the Chatify #
Before using Chatify functionality, you need to initialize it with the appropriate options. Use the init method to initialize the chat with the desired options:
ChatifyController.init(ChatifyOptions(
// Provide the necessary options here
));

The init method initializes the chat functionality by providing the necessary options. Let's go through each field in the ChatifyOptions example and explain its purpose:
ChatifyController.init(ChatifyOptions(
usersCollectionName: 'users'
userData: UserData(
id: 'id', //required
name: 'name', //required
clientNotificationId: 'clientNotificationId', //optional
profileImage: 'profileImage', //optional
uid: 'uid', //optional
searchTerms: 'searchTerms' //optional
),
chatBackground: 'assets/png/chat.png',
notificationKey: 'notificationKeyFromFirebase',
onUserClick: (user) {
Get.to(UserProfile(user: Account.fromJson(user.data)));
},
customMessages: [
MessageWidget(
key: 'reel',
builder: (ctx, msg) => ReelCard(message: msg, width: 300),
),
],
));

Let's go through each field and its purpose:


usersCollectionName (required): The firestore collection of your users data.


userData (required): It represents the mapping model for user data in Firestore collection. In this example, the UserData class is used, which has properties like id, name, clientNotificationId, profileImage, searchTerms, and uid. You need to provide appropriate values for these properties based on your Firestore user data model. If you have searchTerms in your model you can specify to add the ablity to search for users.


chatBackground: It specifies the chat background image. In this example, the path to the chat background image is set to 'assets/png/chat.png'. You can provide the path to your own image asset or leave it as null if you don't want to set a custom background.


notificationKey: It is used to send notifications using Firebase Messaging. In this example, the value 'notificationKeyFromFirebase' is provided. You need to configure Firebase Messaging in your app and obtain the appropriate notification key to use here. If you don't want to send notifications, you can leave this field as null.


onUserClick: It is a callback function that is invoked when a user's image is clicked. In this example, it navigates to a user profile screen using the Get.to method from the GetX package. You can customize this callback function to perform any action you want when a user is clicked.


customMessages: It allows you to add custom message types to the chat. In this example, a custom message widget is added with the key 'reel' and a builder function that returns a ReelCard widget. You can add your own custom message types by providing a unique key and a builder function that returns the widget for that message type.


By providing the appropriate values for each field in the ChatifyOptions object, you can customize and configure the chat functionality according to your specific requirements.
