The CometChat Calls SDK enables real-time voice and video calling capabilities in your Flutter application. Built on top of WebRTC, it provides a complete calling solution with built-in UI components and extensive customization options.
To set up the CometChat Calls SDK and utilize CometChat for your calling functionality, you'll need to follow these steps:
- Registration: Go to the CometChat Dashboard and sign up for an account.
- After registering, log into your CometChat account and create a new app. Once created, CometChat will generate an Auth Key and App ID for you. Keep these credentials secure as you'll need them later.
- Check the Key Concepts to understand the basic components of CometChat.
Add the dependency to your pubspec.yaml:
dependencies:
cometchat_calls_sdk: ^5.1.0| Platform | Minimum |
|---|---|
| iOS | 15.1, built with Swift Package Manager and Xcode 26.1.1 or later |
| Android | API 26 (Android 8.0), compileSdk 36, Android Gradle Plugin 8.9.1 |
iOS: the plugin builds with Swift Package Manager only, since the native
Calls SDK 5.1 is not on the CocoaPods trunk. It is on by default from Flutter
3.44; on an older Flutter, or if your app turned it off, run
flutter config --enable-swift-package-manager.
Android: declare the plugin's ongoing call service in your app's
AndroidManifest.xml, inside <application>. Without it, Android stops the
microphone and camera when the app goes to the background:
<service
android:name="com.cometchatcalls.cometchatcalls_plugin.services.OngoingCallService"
android:exported="false"
android:foregroundServiceType="microphone|camera" />Upgrading from 5.0.x? See the 5.1.0 changelog for the breaking changes.
