    style={{ width: Dimensions.get('window').width - 15, marginTop: 35 }}
    customScript={`document.body.style.background = 'lightyellow';`}

demo

You may have to use yarn to install the dependencies of the demo and remove demo/node_modules/react-native-autoheight-webview/demo manually, cause of installing a local package with npm will create symlink, but there is no supporting of React Native to symlink (https://github.com/facebook/watchman/issues/105).
