Inline Android and iOS WebView

Presumably this requires some compositor work, similar to maps or video?

Adding an example use case for this:

I have a hybrid Android application where some rendering is handled by a WebView but controls for things like navigation are handled by native UI widgets. I would like to port a version to Flutter, off the top of my head the requirements for getting this to work are:

• A way to add a WebView into the rendered tree so that it can live along side native widgets for things like navigation buttons.
• A way to allow interaction with JS in the WebView (something like [this](http://developer.android.com/reference/android/webkit/WebView.html#addJavascriptInterface%28java.lang.Object, java.lang.String%29)).
• A way to intercept HTTP requests from the WebView.

The last item here allows us to stream the contents of PDF files to the WebView. The current Android implementation intercepts HTTP requests from the WebView and streams back the contents of the requested PDF file. The implementation can be seen here.

I'm new to Flutter so I may have gotten some of the terminology wrong, let me know if you need clarification on anything.

We're currently moving towards an approach of making it easier to use native views in conjunction with FlutterView:

This is more about having a way to put a WebView within a Flutter widget tree, I think. As you say in your original comment, we need something similar for embedding videos or maps provided by a third-party non-Flutter library.

Any updates on integrating a webview with flutter?

Looks like someone has started a plugin to do full screen webviews: https://github.com/dart-flitter/flutter_webview_plugin
