Usage

Integration

CometChatIncomingCall being a custom widget, offers versatility in its integration. It can be seamlessly launched via button clicks or any user-triggered action, enhancing the overall user experience and facilitating smoother interactions within the application.

You can launch CometChatIncomingCall directly using Navigator.push, or you can define it as a widget within the build method of your State class.

1. Using Navigator to Launch CometChatIncomingCall
Navigator.push(context, MaterialPageRoute(builder: (context) => CometChatIncomingCall(user: user, call: callObject))); // User object and Call object is required to launch the incoming call widget.
2. Embedding CometChatIncomingCall as a Widget in the build Method
import 'package:cometchat_calls_uikit/cometchat_calls_uikit.dart';
import 'package:flutter/material.dart';

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


State<IncomingCallExample> createState() => _IncomingCallExampleState();
}

class _IncomingCallExampleState extends State<IncomingCallExample> {


Widget build(BuildContext context) {
return Scaffold(
body: SafeArea(
child: CometChatIncomingCall(
user: user, // User Object
call: callObject
), // User object and Call object is required to launch the incoming call widget.
),
);
}
}

Actions

Actions dictate how a widget functions. They are divided into two types: Predefined and User-defined. You can override either type, allowing you to tailor the behavior of the widget to fit your specific needs.

1. onAccept

The onAccept action is typically triggered when the user clicks on the accept button, initiating a predefined action. However, by implementing the following code snippet, you can easily customize or override this default behavior to suit your specific requirements.

CometChatIncomingCall(
user: user, // User Object
call: callObject, // Call Object
onAccept: (BuildContext context, Call call) {
// TODO("Not yet implemented")
},
)

2. onDecline

The onDecline action is typically triggered when the user clicks on the reject button, initiating a predefined action. However, by implementing the following code snippet, you can easily customize or override this default behavior to suit your specific requirements.

CometChatIncomingCall(
user: user, // User Object
call: callObject, // Call Object
onDecline: (BuildContext context, Call call) {
// TODO("Not yet implemented")
},
)

3. onError

You can customize this behavior by using the provided code snippet to override the onError and improve error handling.

CometChatIncomingCall(
user: user, // User Object
call: callObject, // Call Object
onError: (e) {
// TODO("Not yet implemented")
},
)

Filters

Filters allow you to customize the data displayed in a list within a Widget. You can filter the list based on your specific criteria, allowing for a more customized. Filters can be applied using RequestBuilders of Chat SDK.

The CometChatIncomingCall widget does not have any exposed filters.


Events

Events are emitted by a Widget. By using event you can extend existing functionality. Being global events, they can be applied in Multiple Locations and are capable of being Added or Removed.

The CometChatIncomingCall widget does not have any exposed events.


Customization

To fit your app's design requirements, you can customize the appearance of the conversation widget. We provide exposed methods that allow you to modify the experience and behavior according to your specific needs.

Style

You can customize the appearance of the CometChatIncomingCall Widget by applying the CometChatIncomingCallStyle to it using the following code snippet.

Functionality

These are a set of small functional customizations that allow you to fine-tune the overall experience of the widget. With these, you can change text, set custom icons, and toggle the visibility of UI elements.

Example

In this example, we're enhancing the interface by customizing the accept and decline button icons. By setting custom icons for both the accept and decline buttons, users can enjoy a more visually appealing and personalized experience.

This level of customization allows developers to tailor the user interface to match the overall theme and branding of their application.

Here is the complete example for reference:

CometChatIncomingCall(
user: user, // User Object
call: callObject, // Call Object
disableSoundForCalls: true,
declineButtonText: "Decline",
acceptButtonText: "Accept"
)
