Outgoing Call
Overview
The CometChatOutgoingCall
Widget is a visual representation of a user-initiated call, whether it's a voice or video call. It serves as an interface for managing outgoing calls, providing users with essential options to control the call experience. This Widget typically includes information about the call recipient, call controls for canceling the call, and feedback on the call status, such as indicating when the call is in progress.

You can launch CometChatOutgoingCall
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 CometChatOutgoingCall
- Dart
Navigator.push(context, MaterialPageRoute(builder: (context) => CometChatOutgoingCall(user: user, call: callObject))); // User object and Call object is required to launch the incoming call widget.
2. Embedding CometChatOutgoingCall
as a Widget in the build Method
- Dart
import 'package:cometchat_calls_uikit/cometchat_calls_uikit.dart';
import 'package:flutter/material.dart';
class OutgoingCallExample extends StatefulWidget {
const OutgoingCallExample({super.key});
State<OutgoingCallExample> createState() => _OutgoingCallExampleState();
}
class _OutgoingCallExampleState extends State<OutgoingCallExample> {
Widget build(BuildContext context) {
return Scaffold(
body: SafeArea(
child: CometChatOutgoingCall(
user: user, // User Object
call: callObject
), // User object and Call object is required to launch the incoming call widget.
),
);
}
}
Actions
Actions dictate how a component functions. They are divided into two types: Predefined and User-defined. You can override either type, allowing you to tailor the behavior of the component to fit your specific needs.
1. onCancelled
The onCancelled
action is typically triggered when the call is ended, carrying out default actions. However, with the following code snippet, you can effortlessly customize or override this default behavior to meet your specific needs.
- Dart
CometChatOutgoingCall(
user: user, // User Object
call: callObject, // Call Object
onCancelled: (BuildContext context, Call call) {
// TODO("Not yet implemented")
},
)
2. onError
You can customize this behavior by using the provided code snippet to override the onError
and improve error handling.
- Dart
CometChatOutgoingCall(
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 CometChatOutgoingCall
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.
Events emitted by the Outgoing call Widget are as follows.
Event | Description |
---|---|
ccCallAccepted | Triggers when the outgoing call is accepted. |
ccCallRejected | Triggers when the outgoing call is rejected. |
Example
Here is the complete example for reference:
- Dart
import 'package:cometchat_chat_uikit/cometchat_chat_uikit.dart';
import 'package:flutter/material.dart';
class YourScreen extends StatefulWidget {
const YourScreen({super.key});
State<YourScreen> createState() => _YourScreenState();
}
class _YourScreenState extends State<YourScreen> with CometChatCallEventListener {
void initState() {
super.initState();
CometChatCallEvents.addCallEventsListener("unique_listener_ID", this); // Add the listener
}
void dispose(){
super.dispose();
CometChatCallEvents.removeCallEventsListener("unique_listener_ID"); // Remove the listener
}
void ccCallAccepted(Call call) {
// TODO("Not yet implemented")
}
void ccCallRejected(Call call) {
// TODO("Not yet implemented")
}
Widget build(BuildContext context) {
return const Placeholder();
}
}
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 CometChatOutgoingCall
Widget by applying the CometChatOutgoingCallStyle
to it using the following code snippet.
Example
Here is the complete example for reference:
- Dart
CometChatOutgoingCall(
user: user, // User Object
call: callObject, // Call Object
outgoingCallStyle: CometChatOutgoingCallStyle(
avatarStyle: CometChatAvatarStyle(

borderRadius: BorderRadius.circular(8),

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 decline button icons. By setting custom icons for 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.

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