Flutter WebRTC plugin for iOS/Android.

Flutter-WebRTC #

pub package Flutter WebRTC plugin for iOS/Android

Usage #

Add flutter_webrtc as a dependency in your pubspec.yaml file.

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.

Android #

Ensure the following permission is present in your Android Manifest file, located in `

<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" />

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

Functionality #

We intend to implement support the following features:
