Installation

Add dependency

Add the dependency from command-line

$ flutter pub add waterbus_sdk

The command above will add this to the pubspec.yaml file in your project (you can do this manually):

dependencies:
    waterbus_sdk: ^1.3.15

Usage

Initialize

Firstly, call WaterbusSdk.instance.initial to set your server url and sdk connect WebSocket.

await WaterbusSdk.instance.initial(
  apiUrl: 'https://service.waterbus.tech/busapi/v1/',
  wsUrl: 'wss://sfu.waterbus.tech',
);

Create room

final Meeting? meeting = await WaterbusSdk.instance.createRoom(
  meeting: Meeting(title: 'Meeting with Kai Dao'),
  password: 'password',
  userId: 1, // <- modify to your user id
);

Update room

final Meeting? meeting = await WaterbusSdk.instance.updateRoom(
  meeting:  Meeting(title: 'Meeting with Kai Dao - 2'),
  password: 'new-password',
  userId: 1, // <- modify to your user id
);

Join room

final Meeting? meeting = await WaterbusSdk.instance.joinRoom(
  meeting: _currentMeeting,
  password: 'room-password-here',
  userId: 1, // <- modify to your user id
);

Set callback room events

void _onEventChanged(CallbackPayload event) {
  switch (event.event) {
    case CallbackEvents.shouldBeUpdateState:
      break;
    case CallbackEvents.newParticipant:
      break;
    case CallbackEvents.participantHasLeft:
      break;
    case CallbackEvents.meetingEnded:
      break;
    default:
      break;
  }
}

WaterbusSdk.instance.onEventChangedRegister = _onEventChanged;

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();

Configuration

Android

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
    }
}

iOS

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.

Note for iOS.

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
