Answer 1

This is working for me,

static navigationOptions = ({ navigation }) => {
       return {
            tabBarOnPress: ({previousScene, scene, jumpToIndex}) => {
                const { route, index, focused} = scene;

                if(focused){
                    navigation.state.params.scrollToTop()
                }
                jumpToIndex(0)
            }
        }
 };
