• Join room

    await WaterbusSdk.instance.joinRoom(
      roomId: roomCode,
      participantId: participantId,
      onNewEvent: (event) {
        switch (event.event) {
          case CallbackEvents.shouldBeUpdateState:
            // rebuild your ui
            break;
          case CallbackEvents.newParticipant:
            final String? participantId = event.participantId;
            if (participantId == null) return;

            // add new participant to your ui
            break;
          case CallbackEvents.participantHasLeft:
            final String? participantId = event.participantId;
            if (participantId == null) return;

            // remove participant to your ui
            break;
          default:
            break;
        }
      },
    );

• Leave room

await WaterbusSdk.instance.leaveRoom();

• Prepare Media (will prepare the camera and microphone for you to turn on and off before entering the meeting)

await WaterbusSdk.instance.prepareMedia();

• Include this package to your pubspec.yaml

waterbus_sdk:
    git:
      url: https://github.com/waterbustech/waterbus-flutter-sdk.git
      path: '.'
      ref: 0.0.1

Ensure the following permission is present in your Android Manifest file, located in <project root>/android/app/src/main/AndroidManifest.xml:

<uses-feature android:name="android.hardware.camera" />
<uses-feature android:name="android.hardware.camera.autofocus" />
<uses-permission android:name="android.permission.CAMERA" />
<uses-permission android:name="android.permission.RECORD_AUDIO" />
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
<uses-permission android:name="android.permission.CHANGE_NETWORK_STATE" />
<uses-permission android:name="android.permission.MODIFY_AUDIO_SETTINGS" />

If you need to use a Bluetooth device, please add:

<uses-permission android:name="android.permission.BLUETOOTH" android:maxSdkVersion="30" />
<uses-permission android:name="android.permission.BLUETOOTH_ADMIN" android:maxSdkVersion="30" />

The Flutter project template adds it, so it may already be there.

Also you will need to set your build settings to Java 8, because official WebRTC jar now uses static methods in EglBase interface. Just add this to your app level build.gradle:

android {
    //...
    compileOptions {
        sourceCompatibility JavaVersion.VERSION_1_8
        targetCompatibility JavaVersion.VERSION_1_8
    }
}

Add the following entry to your Info.plist file, located in <project root>/ios/Runner/Info.plist:

<key>NSCameraUsageDescription</key>
<string>$(PRODUCT_NAME) Camera Usage!</string>
<key>NSMicrophoneUsageDescription</key>
<string>$(PRODUCT_NAME) Microphone Usage!</string>

This entry allows your app to access camera and microphone.

The WebRTC.xframework compiled after the m104 release no longer supports iOS arm devices, so need to add the config.build_settings['ONLY_ACTIVE_ARCH'] = 'YES' to your ios/Podfile in your project

ios/Podfile

post_install do |installer|
  installer.pods_project.targets.each do |target|
    flutter_additional_ios_build_settings(target)
     target.build_configurations.each do |config|
      # Workaround for https://github.com/flutter/flutter/issues/64502
      config.build_settings['ONLY_ACTIVE_ARCH'] = 'YES' # <= this line
     end
  end
end
