* add allowFileAccessFromFileURLs propery to do the expected on android

* Added types

* Update WebViewTypes.ts

* feat(new prop): containerStyle

* chore(docs): Add documentation for `containerStyle`

* Filter out extra onLoadProgress calls; add url to onLoadProgress

* remove note about onLoadProgress not having the url property in docs

* Update Reference.md

* Add callback for WKWebView's onContentProcessDidTerminate

* Add platform information to docs

* Add new WebViewTerminatedEvent type

After needing to see what the origin of a "html" source'd WebView would be, I found the documentation that baseUrl would be utilized for the "origin" header when CORS requests are made.

Apple required us to remove this (see #819)

BREAKING CHANGE: UIWebView has been removed
BREAKING CHANGE: useWebkit prop removal
BREAKING CHANGE: scalesPageToFit prop removal on iOS (since it's not compatible with WKWebview)
BREAKING CHANGE: Renamed RNCWKWebView to RNCWebView on iOS

* Adding a `contentInsetAdjustmentBehavior` prop to the WebView for iOS.
This controls the way iOS will automatically adjust the insets when the
webview is behind things like the iPhone X notch.

* Removing the code to explicitly pass contentInsetAdjustmentBehavior to the WebView since it is already passed in otherProps.

added doc for the `textZoom` property

* Pass mainDocumentURL to onShouldStartLoadWithRequest

* Update reference

* Update typescript types

* Update WebViewTypes.ts

Added a note about the baseUrl usage since this has been the cause of some filed issues e.g. https://github.com/react-native-community/react-native-webview/issues/526#issuecomment-498067637

* Extract WebChromeClient from an anonymous class

* Support fullscreen videos on Android

Forces landscape mode while playing.

* Use sticky immersive mode for fullscreen videos

No longer forces landscape mode as that is a problem for portrait videos - allow
the user to rotate as necessary.

Only supports KitKat or greater, and falls back to leaving the status and navigation
bars visible for lower than KitKat. This is the easiest way to prevent issues with
resizing the video during playback.

Also implement a lifecyle event listener which means if a user backgrounds the app
or locks the screen with the video fullscreen, the UI visibility is re-applied.

* Add allowsFullscreenVideo prop to control whether videos can be fullscreen on Android

Luckily, we're able to change the WebChromeClient on demand in response to prop changes
without seeming to do any harm. If you switch to disallow fullscreen, it will attempt
to close the currently fullscreened video (if there is one) so users aren't stuck.

I did notice a bug that if you go from fullscreen allowed, to fullscreen disallowed,
the fullscreen button will remain on the video. Tapping the button will have no effect.

* [iOS] Allow focus without user interaction

* Add documentation for keyboardDisplayRequiresUserAction

* set keyboardDisplayRequiresUserAction default to true

We had the problem on iOS WebViews that local cookies (stored in local HTTPCookieStorage, set with  [react-native-cookie](https://github.com/shimohq/react-native-cookie) ) were not added in loadRequests. On Android the local stored cookies were sent like expected.
This kinda "hacky" solution is the only way we found, that works for us.
The stack overview link is in the code below.
If someone finds a better solution we would very much like to accept that.

Rewrote the whole repository into typescript. This will provide way better and up to date documentation. This should also add some safety for people contributing 😄 .
Flow types were not working until now which is why this PR doesn't have them but feel free to PR.

This also fixes #384 #435 #206 #171 #168.

* Added guides for communication between React Native and web pages

* Updated Guide a bit

* Add reference examples for:
- onError
- onNavigationStateChange
- originWhiteList
- renderError
- renderLoading
- onShouldStartLoadWithRequest

* Update to use jsx as code
Add properties of objects passed into methods

* Add examples for:
- onLoad
- onLoadEnd
- onLoadStart
- onLoadProgress
- style

* Add object descriptions, fix style issues, and remove onShouldStartLoad example

Object Descriptions for:
- onLoad
- onLoadEnd
- onLoadStart
- onLoadProgress

* Update Reference.md

Per #320, this adds an example for onShouldStartLoadWithRequest.

I was able to fix a bug with videos loaded from Azure that wouldn't start unless I set that prop to `false`

* Don't allow the scrollview to scroll the WebView body.

* Readme comment

* Remove duplicate protocol def

* Deleted onShouldStartLoadWithRequest platform reference

according to b1b662628e it's supported on android and Ios so  no platfor reference is needed

* Deleted onShouldStartLoadWithRequest platform reference 

Now with added note

fixes #304

fixes #29
fixes #272
fixes #221
fixes #105
fixes #66

BREAKING CHANGE: Communication from webview to react-native has been completely rewritten. React-native-webview will not use or override window.postMessage anymore. Reasons behind these changes can be found throughout so many issues that it made sense to go that way.

Instead of using window.postMessage(data, *), please now use window.ReactNativeWebView.postMessage(data).

Side note: if you wish to keep compatibility with the old version when you upgrade, you can use the injectedJavascript prop to do that:

const injectedJavascript = `(function() {
  window.postMessage = function(data) {
    window.ReactNativeWebView.postMessage(data);
  };
})()`;

Huge thanks to @jordansexton and @KoenLav!

Added a new cacheEnabled prop to toggle Android & iOS webview caching behavior.

BREAKING CHANGE:  This change makes caching enabled by default when previously there was no caching behavior which may cause unexpected behaviour changes in your existing implementations.

* add test code for disable hardware acceleration

* add interface to disable android hardware acceleration

* Update index.d.ts

Allows the webview to be opened with an ephemeral data storage.

* add style doc in reference.md

* Update Reference.md

In the current code using `startInLoadingState` and `injectedJavaScript` will result in an infinite loading state if `injectedJavaScript` fails to evaluate for some reason. This adds a red box error explaining there was a failure to evaluate javascript. In my case this was do to the JS string not returning a valid type so I've added a that as a potential solution in the error message and added some documentation to the API Reference with some additional warnings.

To reproduce the existing behavior setup a webview with `startInLoadingState` and `injectedJavaScript` that returns an invalid type (in my case it returned a function). You should see an infinite loading state as `onLoadEnd` is never called.

Try the same with this branch and you'll get a nice red box error suggesting one potential solution to the problem.
