Finally, creating a ZegoCloud account and creating a live audio room project in ZegoCloud is completed and successful.
How to build a ZegoCloud Live Audio Room application with Flutter. You can read about it below.
Okay, I will assist you in creating a Live Audio Room application in Flutter by utilizing the features provided by ZegoCloud.
I assume that you have already created an account and set up a ZegoCloud project by following the tutorial above.
Creating a Flutter Project for Live Audio Room with ZegoCloud
First, create a Flutter project either through the terminal or VSCode. I hope you are already familiar with and proficient in creating Flutter projects.
After that, you open the ZegoCloud documentation to implement the live audio room in Flutter. You can visit it through the following link: Flutter Dart Live Audio Room Kit SDK Quick start | ZEGOCLOUD Documentation.
Follow the steps inside.
On the sidebar, select Quick Start.
The first requirement is to go to the ZegoCloud admin console to obtain the AppId and AppSign. I hope you already know where it is. As I mentioned in the previous content, I have provided the link earlier.
After that, integrate the SDK from ZegoCloud's live audio room by adding the following dependency.
flutter pub add zego_uikit_prebuilt_live_audio_room
You can add the above command through the terminal console or using the Pubspec Assist library in VS Code.
If successfully added, it will appear in the pubspec.yaml.
After that, create a Dart file to store the AppId and AppSign from ZegoCloud.
Create it with the name constant_zego.dart and fill in the following code.
class ConstantZegoCloud {
static int appId = AppId_anda;
static String appSign ='AppSign_anda';
}
The AppId and AppSign can be seen as in the following image.
Next, create live_page.dart to display the live page. Insert the following code into it.
import 'package:flutter/material.dart';
import 'package:zego_uikit_prebuilt_live_audio_room/zego_uikit_prebuilt_live_audio_room.dart';
import 'package:flutter_live_audio_room_zego_cloud/constant_zego.dart';
class LivePage extends StatelessWidget {
final String roomID;
final bool isHost;
final String userName;
final String userId;
const LivePage({
Key? key,
required this.roomID,
required this.isHost,
required this.userName,
required this.userId,
}) : super(key: key);
@override
Widget build(BuildContext context) {
return SafeArea(
child: ZegoUIKitPrebuiltLiveAudioRoom(
appID: ConstantZegoCloud
.appId, // Fill in the appID that you get from ZEGOCLOUD Admin Console.
appSign: ConstantZegoCloud
.appSign, // Fill in the appSign that you get from ZEGOCLOUD Admin Console.
userID: userId,
userName: userName,
roomID: roomID,
config: (isHost
? ZegoUIKitPrebuiltLiveAudioRoomConfig.host()
: ZegoUIKitPrebuiltLiveAudioRoomConfig.audience())
..background = background()
..userAvatarUrl = 'https://robohash.org/$userId.png'),
);
}
Widget background() {
/// For background live page
return Stack(
children: [
Container(
decoration: BoxDecoration(
image: DecorationImage(
fit: BoxFit.fill,
image: Image.asset('assets/images/bg.jpeg').image,
),
),
),
const Positioned(
top: 10,
left: 10,
child: Text(
'Live Audio Room',
overflow: TextOverflow.ellipsis,
style: TextStyle(
color: Color(0xff1B1B1B),
fontSize: 20,
fontWeight: FontWeight.w800,
),
)),
Positioned(
top: 10 + 20,
left: 10,
child: Text(
'ID: $roomID',
overflow: TextOverflow.ellipsis,
style: const TextStyle(
color: Color(0xff606060),
fontSize: 16,
fontWeight: FontWeight.w500,
),
),
)
],
);
}
}
In the above code, the ZegoUIKitPrebuiltLiveAudioRoom widget is a UI kit widget from ZegoCloud used to display the Live Audio Room.
Then, the background() widget function is used to change the background of the live page. Meanwhile, userAvatarUrl is used to change the user's avatar when logged in and entering the live room.
The next step is to create login_page.dart because we will log in first before conducting live audio. Insert the following code into login_page.dart.
import 'package:flutter/material.dart';
import 'package:flutter_live_audio_room_zego_cloud/live_page.dart';
class LoginPage extends StatefulWidget {
const LoginPage({super.key});
@override
State<LoginPage> createState() => _LoginPageState();
}
class _LoginPageState extends State<LoginPage> {
final usernameController = TextEditingController();
final roomIdController = TextEditingController();
bool isHost = false;
@override
void dispose() {
usernameController.dispose();
roomIdController.dispose();
super.dispose();
}
@override
Widget build(BuildContext context) {
return Scaffold(
appBar: AppBar(
title: const Text(
'Join Live Audio Room',
style: TextStyle(
color: Colors.white,
),
),
centerTitle: true,
),
body: Padding(
padding: const EdgeInsets.all(20.0),
child: SingleChildScrollView(
child: Column(
mainAxisAlignment: MainAxisAlignment.center,
children: [
Image.asset(
'assets/images/live.png',
width: 150,
height: 150,
),
const SizedBox(
height: 15,
),
const Center(
child: Text(
'Podcast With Friends',
style: TextStyle(
color: Colors.black,
fontWeight: FontWeight.bold,
fontSize: 20,
),
),
),
const SizedBox(
height: 30,
),
TextField(
controller: usernameController,
decoration: const InputDecoration(labelText: 'Username'),
),
const SizedBox(
height: 8,
),
TextField(
controller: roomIdController,
decoration: const InputDecoration(labelText: 'RoomID'),
),
const SizedBox(
height: 8,
),
Row(
children: [
const Text('Host ?'),
const SizedBox(
width: 4,
),
Switch(
value: isHost,
onChanged: (val) {
setState(() {
isHost = val;
});
}),
],
),
const SizedBox(
height: 16,
),
ElevatedButton(
onPressed: () {
Navigator.push(context, MaterialPageRoute(builder: (context) {
return LivePage(
roomID: roomIdController.text,
isHost: isHost,
userName: usernameController.text,
userId:
usernameController.text.replaceAll(' ', '').trim());
}));
},
style: ElevatedButton.styleFrom(
backgroundColor: Colors.green.shade300,
foregroundColor: Colors.green.shade300,
fixedSize: const Size(400, 50),
),
child: const Text(
'Join Room',
style: TextStyle(
color: Colors.white,
fontWeight: FontWeight.bold,
fontSize: 16,
),
),
),
],
),
),
),
);
}
}
Next, go to the main.dart file and insert the code exactly as follows.
import 'package:flutter/material.dart';
import 'package:flutter_live_audio_room_zego_cloud/login_page.dart';
void main() {
runApp(const MyApp());
}
class MyApp extends StatelessWidget {
const MyApp({super.key});
@override
Widget build(BuildContext context) {
return MaterialApp(
title: 'Flutter Demo',
theme: ThemeData(
colorScheme: ColorScheme.fromSeed(seedColor: Colors.green.shade400),
useMaterial3: true,
appBarTheme: AppBarTheme(
color: Colors.green.shade400,
elevation: 0,
titleTextStyle: const TextStyle(
color: Colors.white,
fontSize: 16.0,
fontWeight: FontWeight.w500,
),
iconTheme: IconThemeData(
color: Colors.green.shade400,
),
),
),
home: const LoginPage(),
debugShowCheckedModeBanner: false,
);
}
}
At this point, you have created all the necessary pages and files. Next, we need to configure for Android and iOS. For this tutorial, I will demonstrate the configuration on Android. For iOS configuration, you can refer to the ZegoCloud documentation for Live Audio Room.
Android Configuration
Modify the compileSdkVersion to 33 and minSdkVersion to 21 in the build.gradle file in Android. You can find it at your_project/android/app/build.gradle.
After that, add permissions to the AndroidManifest.xml file, located here: your_project/app/src/main/AndroidManifest.xml. Copy the following permissions into it.
<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" />
To prevent obfuscation of the SDK's public class names, do the following:
In the folder your_project > android > app, create a file named proguard-rules.pro with the following code as shown below:
-keep class **.zego.** { *; }
-keep class **.**.zego_zpns.** { *; }
Add the following configuration code to the release section of your_project/android/app/build.gradle file.
proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
The Android configuration has been completed. Next, you can proceed with running to try out the results of your coding.
The result will be like the following video.
