React-native-router-flux: Disable backButton on Modal

[GCour]

Is it possible to disable the hardware backButton from popping when a modal is visible?

I'm using a load screen in a modal scene but users on Android can easily press on the back button which will make the load screen pop, even though the data hasn't even loaded yet..

import {BackAndroid} from 'react-native'

then in your component...

componentWillMount() {
    // Disable back button by just returning true instead of Action.pop()
    BackAndroid.addEventListener('hardwareBackPress', () => {return true});
}

Why, not practical /reset/ this method

This is not working for me on RN 0.48, ReactNavigation 2.0 with

componentWillMount = () => BackHandler.addEventListener('hardwareBackPress', () => true);
