I have WebView content are which changes it's height depending on amount of content. So I found a way how to take the height of the content through the document.title attribute onNavigationStateChange. Looks like this:

let html = '<!DOCTYPE html><html><body><script>document.title = document.height;</script></body></html>';

And on onNavigationStateChange

onNavigationStateChange(navState) {
  this.setState({
    height: navState.title
  });
  console.log("DATA");
  console.log(this.state.height)
}

On the actual WebView render I do:

<WebView style={this._setWebviewHeight()}
           automaticallyAdjustContentInsets={false}
           scrollEnabled={false}
           onNavigationStateChange={this.onNavigationStateChange.bind(this)}
           html={html}>
</WebView>

Where: 

_setWebviewHeight() {
 return {
  height: this.state.height,
  padding: 20,
 }
}

And in this case I'm getting error and I am not able to get the height of content through state. What shall I do then?

The idea of solution is taken from here: React native: Is it possible to have the height of a html content in a webview?

Reset to default 2

I have found the solution in the implementation of one of the RN third party libraries. Here is the link to it: https://github./danrigsby/react-native-web-container/blob/master/index.js

With this kind of approach all worked good.

Just try this lib: https://github./iou90/react-native-autoheight-webview It will works both on iOS & Android
