title: Is there any way to pass parameters to previous screen in react navigation without using onPress or onClick Events?
body: <p>I'm doing a React Native Project.In that to change screens i use react navigation which is great.Moving Screens and Passing Parameters is usually bind to a onPress or onClick event as Navigator.navigate('Settings',params) to move from 'Home' to 'Settings' screen.Moving back from Settings to Home is automatically done when pressing back button,without the need to bind it in a Button.But the problem is i can't pass parameters from 'Settings' to 'Home' Screen on going back.How can i resolve this?</p>
