usage

<AutoHeightWebView
    onHeightUpdated={height => console.log(height)},
    // if page contains iframe on iOS, use a specific script for it
    hasIframe={true}
    /*
    if set to false may cause some layout issues (width of container not fit for screen) on android
    if set to true may cause some layout issues (smaller font size) on ios
    */

    enableBaseUrl={true}
    // offset of rn webview margin 
    heightOffset={5}
    // default width is the width of screen
    // to fix that it can not select text when the length of it is not long enough on iOS, the width should be reduced more than 15
    style={{ width: Dimensions.get('window').width - 15 }}
    // enable animation by default
    enableAnimation={true},
    // only works on enable animation
