Configuration

IOS

Note: Example compilable with XCode 12.2 & Flutter 1.22.4.

Podfile

Ensure in your Podfile you have an entry like below declaring platform of 11.0 or above and disable BITCODE.

platform :ios, '11.0'

...

post_install do |installer|
  installer.pods_project.targets.each do |target|
    target.build_configurations.each do |config|
      config.build_settings['ENABLE_BITCODE'] = 'NO'
    end
  end
end

Info.plist

Add NSCameraUsageDescription and NSMicrophoneUsageDescription to your Info.plist.

<key>NSCameraUsageDescription</key>
<string>$(PRODUCT_NAME) MyApp needs access to your camera for meetings.</string>
<key>NSMicrophoneUsageDescription</key>
<string>$(PRODUCT_NAME) MyApp needs access to your microphone for meetings.</string>

Android

Gradle

Set dependencies of build tools gradle to minimum 3.6.3:

dependencies {
    classpath 'com.android.tools.build:gradle:3.6.3' <!-- Upgrade this -->
    classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:$kotlin_version"
}

Set distribution gradle wrapper to minimum 5.6.4.

distributionBase=GRADLE_USER_HOME
distributionPath=wrapper/dists
zipStoreBase=GRADLE_USER_HOME
zipStorePath=wrapper/dists
distributionUrl=https\://services.gradle.org/distributions/gradle-5.6.4-all.zip <!-- Upgrade this -->

AndroidManifest.xml

Jitsi Meet's SDK AndroidManifest.xml will conflict with your project, namely the application:label field. To counter that, go into 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"
    package="yourpackage.com"
    xmlns:tools="http://schemas.android.com/tools"> <!-- Add this -->
    <application 
        tools:replace="android:label"  
        android:name="your.application.name"
        android:label="My Application"
        android:icon="@mipmap/ic_launcher">
        ...
    </application>
...
</manifest>

Minimum SDK Version 23

Update your minimum sdk version to 23 in android/app/build.gradle

defaultConfig {
    applicationId "com.gunschu.jitsi_meet_example"
    minSdkVersion 23 //Required for Jitsi
    targetSdkVersion 28
    versionCode flutterVersionCode.toInteger()
    versionName flutterVersionName
}

Proguard

Jitsi's SDK enables proguard, but without a proguard-rules.pro file, your release apk build will be missing the Flutter Wrapper as well as react-native code. In your Flutter project's android/app/build.gradle file, add proguard support

buildTypes {
    release {
        // TODO: Add your own signing config for the release build.
        // Signing with the debug keys for now, so `flutter run --release` works.
        signingConfig signingConfigs.debug
        
        // Add below 3 lines for proguard
        minifyEnabled true
        useProguard true
        proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
    }
}

Then add a file in the same directory called proguard-rules.pro. See the example app's proguard-rules.pro file to know what to paste in.

Note
If you do not create the proguard-rules.pro file, then your app will crash when you try to join a meeting or the meeting screen tries to open but closes immediately. You will see one of the below errors in logcat.

## App crashes ##

.....

WEB

To implement you need to include Jitsi Js library in the index.html of web section

<script src="https://meet.jit.si/external_api.js" type="application/javascript"></script>

Example:

<body>
  <!-- This script installs service_worker.js to provide PWA functionality to
       application. For more information, see:
       https://developers.google.com/web/fundamentals/primers/service-workers -->
  <script>
    if ('serviceWorker' in navigator) {
      window.addEventListener('load', function () {
        navigator.serviceWorker.register('/flutter_service_worker.js');
      });
    }
  </script>
  <script src="https://meet.jit.si/external_api.js" type="application/javascript"></script>
  <script src="main.dart.js" type="application/javascript"></script>
</body>
</html>

Note See usage example in jitsi_meet plugin

FeatureFlag

Feature flag allows you to limit video resolution and enable/disable few features of Jitsi Meet SDK mentioned in the list below.
If you don't provide any flag to JitsiMeetingOptions, default values will be used.

We are using the official list of flags, taken from the Jitsi Meet repository

`conferenceTimerEnabled`	true	true	Enable conference timer.
`chatEnabled`	true	true	Enable chat (button and feature).
`inviteEnabled`	true	true	Enable invite option in menu.

REMARK about Call integration Call integration on Android (known as ConnectionService) has been disabled on the official Jitsi Meet app because it creates a lot of issues. You should disable it too to avoid these issues.

JitsiMeetingResponse

Field	Type	Description
isSuccess	bool	Success indicator.
message	String	Success message or error as a String.
error	dynamic	Optional, only exists if isSuccess is false. The error object.

Listening to Meeting Events

Events supported

onConferenceJoined	User has joined meeting.
onConferenceTerminated	User has exited the conference.
onPictureInPictureWillEnter	User entered PIP mode.
onPictureInPictureTerminated	User exited PIP mode.
onError	Error has occurred with listening to meeting events.

Per Meeting Events

To listen to meeting events per meeting, pass in a JitsiMeetingListener in joinMeeting. The listener will automatically be removed when an
onConferenceTerminated event is fired.

await JitsiMeet.joinMeeting(options,
  listener: JitsiMeetingListener(onConferenceWillJoin: ({message}) {
    debugPrint("${options.room} will join with message: $message");
  }, onConferenceJoined: ({message}) {
    debugPrint("${options.room} joined with message: $message");
  }, onConferenceTerminated: ({message}) {
    debugPrint("${options.room} terminated with message: $message");
  }, onPictureInPictureWillEnter: ({message}) {
	debugPrint("${options.room} entered PIP mode with message: $message");
  }, onPictureInPictureTerminated: ({message}) {
	debugPrint("${options.room} exited PIP mode with message: $message");
  }));

Global Meeting Events

To listen to global meeting events, simply add a JitsiMeetListener with
JitsiMeet.addListener(myListener). You can remove listeners using
JitsiMeet.removeListener(listener) or JitsiMeet.removeAllListeners().

@override
void initState() {
  super.initState();
  JitsiMeet.addListener(JitsiMeetingListener(
    onConferenceWillJoin: _onConferenceWillJoin,
    onConferenceJoined: _onConferenceJoined,
    onConferenceTerminated: _onConferenceTerminated,
    onPictureInPictureWillEnter: _onPictureInPictureWillEnter,
    onPictureInPictureTerminated: _onPictureInPictureTerminated,
    onError: _onError));
}

@override
void dispose() {
  super.dispose();
  JitsiMeet.removeAllListeners();
}

_onConferenceWillJoin({message}) {
  debugPrint("_onConferenceWillJoin broadcasted");
}

_onConferenceJoined({message}) {
  debugPrint("_onConferenceJoined broadcasted");
}

_onConferenceTerminated({message}) {
  debugPrint("_onConferenceTerminated broadcasted");
}

_onPictureInPictureWillEnter({message}) {
debugPrint("_onPictureInPictureWillEnter broadcasted with message: $message");
}

_onPictureInPictureTerminated({message}) {
debugPrint("_onPictureInPictureTerminated broadcasted with message: $message");
}

_onError(error) {
  debugPrint("_onError broadcasted");
}
