a ZEGOCLOUD developer account – Sign up
Install and configure Flutter on your computer.
Make sure you have Android or iOS devices with audio and internet connectivity.
Navigate to the ZEGOCLOUD Admin Console:

Create a new project, and make a note of the generated AppID and AppSign.
Enable the In-app Chat service by activating it within the console.

Live Audio Room SDK Integration

If you want to use the Live Audio Room Kit SDK to create karaoke tracks, here’s what you need to do:

Add the ZegoUIKitPrebuiltLiveAudioRoom to your project directory by running this code in the root directory of your project:

flutter pub add zego_uikit_prebuilt_live_audio_room

Import the SDK into your main.dart file by adding this line of code:

import 'package:zego_uikit_prebuilt_live_audio_room/zego_uikit_prebuilt_live_audio_room.dart';

With these steps complete, you’ll be ready to start using the Live Audio Room Kit SDK to create your own karaoke tracks.

Using the Live Audio Room Kit to Make a Karaoke Track

To use Live Audio Room Kit, you’ll need your userID username. The roomID is the identifier of the live audio room you wish to join. Please provide accurate information in order to gain access to the service.

class LivePage extends StatelessWidget {
  final String roomID;
  final bool isHost;

  const LivePage({Key? key, required this.roomID, this.isHost = false}) : super(key: key);

  @override
  Widget build(BuildContext context) {
    return SafeArea(
      child: ZegoUIKitPrebuiltLiveAudioRoom(
        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',
        roomID: roomID,
        config: isHost
            ? ZegoUIKitPrebuiltLiveAudioRoomConfig.host()
            : ZegoUIKitPrebuiltLiveAudioRoomConfig.audience(),
      ),
    );
  }
}

With the ability to create a live audio room at your fingertips, it’s easy to host virtual events and gatherings. Simply set up the room and share the unique roomID with your intended audience, and they’ll be able to join in and participate in the live audio experience with you.

Configure your project (Android)

In order to properly integrate the SDK into your Flutter project, there are a few key steps you’ll need to follow.

First, open the your_project/android/app/build.gradle file and modify the compileSdkVersion to be set to 33.
Next, you’ll need to add several permissions to your project by opening the AndroidManifest.xml file located in the app/src/main directory of your project. Simply add the following lines of code to include the necessary permissions:

<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" />

In order to ensure that the public class names in the SDK are not obscured during the build process, it is necessary to create a file called proguard-rules.pro within the android > app directory of your project.

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

Then, in the release section of the your_project/android/app/build.gradle file, include the following configuration code:

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

Configure your project (iOS)

To add necessary permissions and disable Bitcode in your iOS project, you can follow these steps:

Open the Podfile located in the your_project/ios directory.

In the post_install do |installer| section, add the following code snippet to enable camera and microphone permissions in your app:

# Start of the permission_handler configuration
target.build_configurations.each do |config|
  config.build_settings['GCC_PREPROCESSOR_DEFINITIONS'] ||= [
    '$(inherited)',
    'PERMISSION_CAMERA=1',
    'PERMISSION_MICROPHONE=1',
  ]
end
# End of the permission_handler configuration

Open the Info.plist located in the your_project/ios/Runner directory. In the dict section, add the following lines of code to provide descriptions for the camera and microphone permissions that will be displayed to the user when they are requested:

<key>NSCameraUsageDescription</key>
<string>We need camera access to connect to a live</string>
<key>NSMicrophoneUsageDescription</key>
<string>We need microphone access to connect to a live</string>

To disable Bitcode, open the Runner.xcworkspace located in the your_project > iOS directory. Select your target project and follow the instructions in the provided images to disable Bitcode.
