​
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
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
import 'package:cometchat_calls_uikit/cometchat_calls_uikit.dart';
import 'package:flutter/material.dart';

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

  @override
  State<OutgoingCallExample> createState() => _OutgoingCallExampleState();
}

class _OutgoingCallExampleState extends State<OutgoingCallExample> {

  @override
  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. 
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. 
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.
EventDescription
ccCallAcceptedTriggers when the outgoing call is accepted.
ccCallRejectedTriggers when the outgoing call is rejected.
Example Here is the complete example for reference: 
import 'package:cometchat_chat_uikit/cometchat_chat_uikit.dart';
import 'package:flutter/material.dart';

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

  @override
  State<YourScreen> createState() => _YourScreenState();
}

class _YourScreenState extends State<YourScreen> with CometChatCallEventListener {

  @override
  void initState() {
    super.initState();
    CometChatCallEvents.addCallEventsListener("unique_listener_ID", this); // Add the listener
  }

  @override
  void dispose(){
    super.dispose();
    CometChatCallEvents.removeCallEventsListener("unique_listener_ID"); // Remove the listener
  }

  @override
  void ccCallAccepted(Call call) {
    // TODO("Not yet implemented")
  }

  @override
  void ccCallRejected(Call call) {
    // TODO("Not yet implemented")
  }

  @override
  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: 
CometChatOutgoingCall(
  user: user, // User Object
  call: callObject, // Call Object
  outgoingCallStyle: CometChatOutgoingCallStyle(
       avatarStyle: CometChatAvatarStyle(
          backgroundColor: Color(0xFFFBAA75),
          borderRadius: BorderRadius.circular(8),
       ),
       declineButtonColor: Color(0xFFF44649),
       declineButtonBorderRadius: BorderRadius.circular(12),
     )
)

​
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. Example Here is the example for reference: 
CometChatOutgoingCall(
    user: user, // User Object
    call: callObject, // Call Object
    disableSoundForCalls: true,
    declineButtonText: "Decline",
)
