 ### `InAppWebView` class
 Flutter Widget for adding an **inline native WebView** integrated into the flutter widget tree.
 
-[AndroidView](https://docs.flutter.io/flutter/widgets/AndroidView-class.html) and [UiKitView](https://docs.flutter.io/flutter/widgets/UiKitView-class.html) are not officially stable yet!
-So, if you want use it, you can but you will have some limitation such as the inability to use the keyboard!
+The plugin relies on Flutter's mechanism (in developers preview) for embedding Android and iOS native views: [AndroidView](https://docs.flutter.io/flutter/widgets/AndroidView-class.html) and [UiKitView](https://docs.flutter.io/flutter/widgets/UiKitView-class.html).
+Known issues are tagged with the [platform-views](https://github.com/flutter/flutter/labels/a%3A%20platform-views) label in the [Flutter official repo](https://github.com/flutter/flutter).
 
 To use `InAppWebView` class on iOS you need to opt-in for the embedded views preview by adding a boolean property to the app's `Info.plist` file, with the key `io.flutter.embedded_views_preview` and the value `YES`.
