Overview

---

Call Kit is a prebuilt feature-rich call component, which enables you to build one-on-one and group voice/video calls into your app with only a few lines of code.

And it includes the business logic with the UI, you can add or remove features accordingly by customizing UI components.

One-on-one call	Group call

When do you need the Call Kit

• Build apps faster and easier

  When you want to prototype 1-on-1 or group voice/video calls ASAP

  Consider speed or efficiency as the first priority

  Call Kit allows you to integrate in minutes

• Customize UI and features as needed

  When you want to customize in-call features based on actual business needs

  Less time wasted developing basic features

  Call Kit includes the business logic along with the UI, allows you to customize features accordingly

To finest-grained build a call app, you may try our Video Call SDK to make full customization.

Embedded features

• Ready-to-use 1-on-1/group calls
• Customizable UI styles
• Real-time sound waves display
• Device management
• Switch views during a 1-on-1 call
• Extendable menu bar
• Participant list
• Call invitation
• Custom call ringtones

Quick start

---

Integrate the SDK

Add ZegoUIKitPrebuiltCall as dependencies

Run the following code in your project root directory:

flutter pub add zego_uikit_prebuilt_call

Import the SDK

Now in your Dart code, import the prebuilt Call Kit SDK.

import 'package:zego_uikit_prebuilt_call/zego_uikit_prebuilt_call.dart';

Using the ZegoUIKitPrebuiltCall in your project

• Go to ZEGOCLOUD Admin Console, get the appID and appSign of your project.
• Specify the userID and userName for connecting the Call Kit service.
• Create a callID that represents the call you want to make.

• userID and callID can only contain numbers, letters, and underlines (_).
• Users that join the call with the same callID can talk to each other.

class CallPage extends StatelessWidget {
  const CallPage({Key? key, required this.callID}) : super(key: key);
  final String callID;

  @override
  Widget build(BuildContext context) {
    return ZegoUIKitPrebuiltCall(
      appID: yourAppID, // Fill in the appID that you get from ZEGOCLOUD Admin Console.
      appSign: yourAppSign, // Fill in the appSign that you get from ZEGOCLOUD Admin Console.
      userID: 'user_id',
      userName: 'user_name',
      callID: callID,
      // You can also use groupVideo/groupVoice/oneOnOneVoice to make more types of calls.
      config: ZegoUIKitPrebuiltCallConfig.oneOnOneVideoCall() 
        ..onOnlySelfInRoom = () => Navigator.of(context).pop(),
    );
  }
}

Now, you can make a new call by navigating to this CallPage.

Configure your project

• Android:

1. If your project is created with Flutter 2.x.x, you will need to open the your_project/android/app/build.gradle file, and modify the compileSdkVersion to 33.

2. Add app permissions. Open the file your_project/app/src/main/AndroidManifest.xml, and add the following code:

   <uses-permission android:name="android.permission.ACCESS_WIFI_STATE" />
   <uses-permission android:name="android.permission.RECORD_AUDIO" />
   <uses-permission android:name="android.permission.INTERNET" />
   <uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
   <uses-permission android:name="android.permission.CAMERA" />
   <uses-permission android:name="android.permission.BLUETOOTH" />
   <uses-permission android:name="android.permission.MODIFY_AUDIO_SETTINGS" />
   <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
   <uses-permission android:name="android.permission.READ_PHONE_STATE" />
   <uses-permission android:name="android.permission.WAKE_LOCK" />
   

   

3. Prevent code obfuscation.

To prevent obfuscation of the SDK public class names, do the following:

a. In your project's your_project > android > app folder, create a proguard-rules.pro file with the following content as shown below:

-keep class **.zego.** { *; }

b. Add the following config code to the release part of the your_project/android/app/build.gradle file.

proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'

• iOS:

To add permissions, open your_project/ios/Runner/Info.plist, and add the following code to the dict part:

<key>NSCameraUsageDescription</key>
<string>We require camera access to connect to a call</string>
<key>NSMicrophoneUsageDescription</key>
<string>We require microphone access to connect to a call</string>

Run & Test

Now you have finished all the steps!

You can simply click the Run or Debug to run and test your App on your device.

Quick start (with call invitation)

---

Integrate the SDK

Prerequisites

• Go to ZEGOCLOUD Admin Console, and do the following:
  • Create a project, get the AppID and AppSign.
  • Activate the In-app Chat service (as shown in the following figure).

Add ZegoUIKitPrebuiltCallWithInvitation as dependencies

1. Edit your project's pubspec.yaml file to add local project dependencies.

dependencies:
  flutter:
    sdk: flutter
  zego_uikit_prebuilt_call: ^1.4.0 # Add this line
  zego_uikit_signaling_plugin: ^1.4.0 # Add this line

2. Run the following code in your project root directory to install all dependencies.

flutter pub get

Import the SDK

Now in your Dart code, import the prebuilt Call Kit SDK.

import 'package:zego_uikit_prebuilt_call/zego_uikit_prebuilt_call.dart';
import 'package:zego_uikit_signaling_plugin/zego_uikit_signaling_plugin.dart';

Integrate the SDK with the call invitation feature

1. Wrap your widget with ZegoUIKitPrebuiltCallWithInvitation, and specify the userID and userName for connecting the Call Kit service.

• userID can only contain numbers, letters, and underlines (_).

@override
Widget build(BuildContext context) {
   return ZegoUIKitPrebuiltCallWithInvitation(
      appID: yourAppID,
      serverSecret: yourServerSecret,
      appSign: yourAppSign,
      userID: userID,
      userName: userName,
      plugins: [ZegoUIKitSignalingPlugin()],
      child: YourWidget(),
   );
}

2. Add the button for making call invitations, and pass in the ID of the user you want to call.

ZegoSendCallInvitationButton(
   isVideoCall: true,
   invitees: [
      ZegoUIKitUser(
         id: targetUserID,
         name: targetUserName,
      ),
      ...
      ZegoUIKitUser(
         id: targetUserID,
         name: targetUserName,
      )
   ],
)

Now, you can make call invitations by simply clicking on this button.

Configure your project

• Android

1. If your project is created with Flutter 2.x.x, you will need to open the your_project/android/app/build.gradle file, and modify the compileSdkVersion to 33.

   

2. Add app permissions.

Open the file your_project/app/src/main/AndroidManifest.xml, and add the following code:

<uses-permission android:name="android.permission.ACCESS_WIFI_STATE" />
<uses-permission android:name="android.permission.RECORD_AUDIO" />
<uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
<uses-permission android:name="android.permission.CAMERA" />
<uses-permission android:name="android.permission.BLUETOOTH" />
<uses-permission android:name="android.permission.MODIFY_AUDIO_SETTINGS" />
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
<uses-permission android:name="android.permission.READ_PHONE_STATE" />
<uses-permission android:name="android.permission.WAKE_LOCK" />
<uses-permission android:name="android.permission.VIBRATE"/>

3. Prevent code obfuscation.

b. Add the following config code to the release part of the your_project/android/app/build.gradle file.

proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'

• iOS

  <key>NSCameraUsageDescription</key>
  <string>We require camera access to connect to a call</string>
  <key>NSMicrophoneUsageDescription</key>
  <string>We require microphone access to connect to a call</string>
