Implement live streaming

Create Project

Run the following code to create a new project.

flutter create --template app.
create project

Add live button

Insert two buttons, one to start life and one to watch live.

add live button
import 'package:flutter/material.dart';

void main() {
  runApp(const MyApp());

class MyApp extends StatelessWidget {
  const MyApp({Key? key}) : super(key: key);

  Widget build(BuildContext context) {
    return const MaterialApp(title: 'Flutter Demo', home: HomePage());

class HomePage extends StatelessWidget {
  const HomePage({Key? key}) : super(key: key);
  Widget build(BuildContext context) {
    return MaterialApp(
      home: Scaffold(
        body: Center(
          child: Column(
            children: [
                  child: const Text('Start a live'),
                  onPressed: () => jumpToLivePage(context, isHost: true)),
                  child: const Text('Watch a live'),
                  onPressed: () => jumpToLivePage(context, isHost: false)),

  jumpToLivePage(BuildContext context, {required bool isHost}) {}

Set ZegoUIKitPrebuiltLiveStreaming as a dependency

Run the following command in your project root directory:

flutter pub add zego_uikit_prebuilt_live_streaming
add live streaming sdk

Import the SDK

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

import 'package:zego_uikit_prebuilt_live_streaming/zego_uikit_prebuilt_live_streaming.dart';
import live streaming sdk

Implement live streaming

Use ZegoUIKitPrebuiltLiveStreaming to quickly build a live-streaming page

class LivePage extends StatelessWidget {
  const LivePage({Key? key, this.isHost = false}) : super(key: key);
  final bool isHost;

  Widget build(BuildContext context) {
    return SafeArea(
      child: ZegoUIKitPrebuiltLiveStreaming(
        appID: , // use your appID
        appSign: 'yourAppSign', // use your appSign
        userID: userID,
        userName: 'user_$userID',
        liveID: 'testLiveID',
        config: isHost
            : ZegoUIKitPrebuiltLiveStreamingConfig.audience(),

Now, you can create a new live or watch a live one by navigating to this live page.

void jumpToLivePage(BuildContext context, {required bool isHost}) {
  Navigator.push(context, MaterialPageRoute(builder: (context) => LivePage(isHost: isHost)));
implement live streaming

Configure your project

  • Android:
  1. You need to open the your_project/android/app/build.gradle file, and modify the compileSdkVersion to 33.
compile sdk version
  1. 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" />
permission android
  1. 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 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'), ''
android class confusion
  • iOS:
  1. Add app permissions.

a. open the your_project/ios/Podfile file, and add the following to the post_install do |installer| part:

# Start of the permission_handler configuration
target.build_configurations.each do |config|
  config.build_settings['GCC_PREPROCESSOR_DEFINITIONS'] ||= [
# End of the permission_handler configuration
permission podfile

b. open the your_project/ios/Runner/Info.plist file, and add the following to the dict part:

    <string>We require camera access to connect to a live</string>
    <string>We require microphone access to connect to a live</string>
permission ios

Run a Demo
