$ flutter pub get

Import files

Import the following files into your dart code:

import 'package:jitsi_meet_flutter_sdk/jitsi_meet_flutter_sdk.dart';

Usage

Join meeting

Firstly, create a JitsiMeet object, then call the method join from it with a JitsiMeetConferenceOptions object

var jitsiMeet = JitsiMeet();
var options = JitsiMeetConferenceOptions(room: 'jitsiIsAwesome');
jitsiMeet.join(options);

Configuration

iOS

Make sure in Podfile from ios directory you set the ios version 12.4 or higher

platform :ios, '12.4'

The plugin requests camera and microphone access, make sure to include the required entries for NSCameraUsageDescription and NSMicrophoneUsageDescription in your Info.plist file from the ios/Runner directory.

<key>NSCameraUsageDescription</key>
<string>The app needs access to your camera for meetings.</string>
<key>NSMicrophoneUsageDescription</key>
<string>The app needs access to your microphone for meetings.</string>

To use the screen sharing feature requires Broadcast Upload Extension. Please check the following to integrate it: https://jitsi.github.io/handbook/docs/dev-guide/dev-guide-ios-sdk/#screen-sharing-integration.

Android

Go to android/app/build.gradle and make sure that the minSdkVersion is set to at lest 24

android {
    ...
    defaultConfig {
        ...
        minSdkVersion 24
    }
}

The application:label field from the Jitsi Meet Android SDK will conflict with your application's one . Go to android/app/src/main/AndroidManifest.xml and add the tools library and tools:replace="android:label" to the application tag.

<manifest xmlns:android="http://schemas.android.com/apk/res/android" 
    xmlns:tools="http://schemas.android.com/tools">
    <application
        tools:replace="android:label"
        android:label="sample_app"
        android:name="${applicationName}"
        android:icon="@mipmap/ic_launcher">
        ...
    </application>
</manifest>
