+
+### WebRTC
+
+To work with WebRTC, you need to request `camera` and `microphone` permissions, for example using the `permission_handler` flutter package:
+```dart
+import 'package:permission_handler/permission_handler.dart';
+
+Future main() async {
+  WidgetsFlutterBinding.ensureInitialized();
+
+  await Permission.camera.request();
+  await Permission.microphone.request();
+
+  runApp(MyApp());
+}
+```
+Also, you need to set the cross-platform option `mediaPlaybackRequiresUserGesture` to `false` in order to autoplay HTML5 audio and video.
+
+After that, follow the instructions below for each platform where you want to use it.
+
+To test WebRTC, you can try to visit https://appr.tc/.
+
+#### WebRTC on Android
+
+On Android, you need to implement the `androidOnPermissionRequest` event, that is an event fired when the WebView is requesting permission to access a specific resource.
+This event is used to grant permissions for the WebRTC API, for example:
+```dart
+androidOnPermissionRequest: (controller, origin, resources) async {
+  return PermissionRequestResponse(resources: resources, action: PermissionRequestResponseAction.GRANT);
+}
+```
+
+Also, you need to add these permissions in your `AndroidManifest.xml` file:
+```xml
+<uses-permission android:name="android.permission.INTERNET"/>
+<uses-permission android:name="android.permission.CAMERA" />
+<uses-permission android:name="android.permission.RECORD_AUDIO" />
+<uses-permission android:name="android.permission.MODIFY_AUDIO_SETTINGS" />
+<uses-permission android:name="android.permission.VIDEO_CAPTURE" />
+<uses-permission android:name="android.permission.AUDIO_CAPTURE" />
+```
+
+#### WebRTC on iOS
+
+On iOS, WebRTC is supported starting from 14.3+.
+
+You need to set the iOS-specific option `allowsInlineMediaPlayback` to `true`, for example:
+```dart
+initialOptions: InAppWebViewGroupOptions(
+  crossPlatform: InAppWebViewOptions(
+    mediaPlaybackRequiresUserGesture: false,
+  ),
+  android: AndroidInAppWebViewOptions(
+    useHybridComposition: true
+  ),
+  ios: IOSInAppWebViewOptions(
+    allowsInlineMediaPlayback: true,
+  )
+),
+```
+Note that on iOS, to be able to play video inline, the `video` HTML element must have the `playsinline` attribute, for example:
+```html
+<video autoplay playsinline src="..."></video>
+```
+In your `Info.plist` file, you need to add also the following properties:
+```xml
+<key>NSMicrophoneUsageDescription</key>
+<string>Flutter requires access to microphone.</string>
+
+<key>NSCameraUsageDescription</key>
+<string>Flutter requires access to camera.</string>
+```
+If you open this file In Xcode, the `NSMicrophoneUsageDescription` property is represented by `Privacy - Microphone Usage Description` and
+`NSCameraUsageDescription` is represented by `Privacy - Camera Usage Description`.
+
+### Service Worker API
+
+Check https://caniuse.com/serviceworkers for JavaScript Service Worker API availability.
+
+#### Service Worker API on Android
+
+On Android, the `AndroidServiceWorkerController` and `AndroidServiceWorkerClient` classes can be used to intercept requests.
+Before using these classes or its methods, you should check if the service worker features you want to use are supported or not, for example:
+```dart
+Future main() async {
+  WidgetsFlutterBinding.ensureInitialized();
+
+  if (Platform.isAndroid) {
+    await AndroidInAppWebViewController.setWebContentsDebuggingEnabled(true);
+
+    var swAvailable = await AndroidWebViewFeature.isFeatureSupported(AndroidWebViewFeature.SERVICE_WORKER_BASIC_USAGE);
+    var swInterceptAvailable = await AndroidWebViewFeature.isFeatureSupported(AndroidWebViewFeature.SERVICE_WORKER_SHOULD_INTERCEPT_REQUEST);
+
+    if (swAvailable && swInterceptAvailable) {
+      AndroidServiceWorkerController serviceWorkerController = AndroidServiceWorkerController.instance();
+
+      serviceWorkerController.serviceWorkerClient = AndroidServiceWorkerClient(
+        shouldInterceptRequest: (request) async {
+          print(request);
+          return null;
+        },
+      );
+    }
+  }
+
+  runApp(MyApp());
+}
+```
+
+#### Service Worker API on iOS
+
+The JavaScript Service Worker API are available starting from iOS 14.0+.
+
+To enable this JavaScript API on iOS there are only 2 ways:
+- using `App-Bound Domains`
+- your App proposes itself as a possible Default Browser such as iOS Safari or Google Chrome
+
+##### iOS App-Bound Domains
+
+Read the [WebKit - App-Bound Domains](https://webkit.org/blog/10882/app-bound-domains/) article for details.
+
+You can specify up to 10 "app-bound" domains using a new Info.plist key `WKAppBoundDomains`, for example:
+```xml
+<dict>
+<key>WKAppBoundDomains</key>
+<array>
+    <string>flutter.dev</string>
+    <string>github.com</string>
+</array>
+</dict>
+```
+
+After that, you need to set to `true` the `limitsNavigationsToAppBoundDomains` iOS-specific WebView option, for example:
+```dart
+InAppWebViewGroupOptions(
+  ios: IOSInAppWebViewOptions(
+    limitsNavigationsToAppBoundDomains: true // adds Service Worker API on iOS 14.0+
+  )
+)
+```
+
+##### iOS Default Browser
+
+Read the [Preparing Your App to be the Default Browser or Email Client](https://developer.apple.com/documentation/xcode/allowing_apps_and_websites_to_link_to_your_content/preparing_your_app_to_be_the_default_browser_or_email_client) article for details.
