React-native-router-flux: Navigation bar backButtonImage - can we use Icon instead if image

[kirankalyan5]

Hi,

I wanted to use Icon (react-native-vector-icons) instead of image in Navigation bar backButtonImage , has anyone tried this, or any alternate way to do this with the same behavior.
Thanks in advance.

const ionicon = (icon) => Platform.OS == 'ios' ? `ios-${icon}` : `md-${icon}`;

renderBackButton={(nav) => {
    return nav.navigationState.index ? (
        <TouchableOpacity onPress={Actions.pop}>
            <Icon name={ionicon('arrow-back')} size={26} color='#FFFFFF' />
        </TouchableOpacity>
    ) : null;
}}

It didn't work for me when i had the renderBackButton in the root Scene.
But when i put it inside individual scenes, it works smoothly.
