Android hardware back button exits app on react navigation

I am using react navigation {create stack navigator} and so many pages. When I press hardware back button it exits app instead of going back.

My friend said that it is may be because of firebase (which I use for autheticating (no db)). Version of firebase 5.3.1 and he gave advice to install 5.0.0 (I've tried npm install [email protected] --save, but it shows some errors and hence is not installed)

And I've asked many of my friends and hardware back button returns goBack, but not for me

What should I do? I've tried to use BackHandler but I'm confused,so it doesn't work

react 16.3.1

react native 0.55.2

react navigation 2.9.3

The issue is with the npm firebase package. This issue can be fixed by changing the way you import firebase. Use: 

import firebase from "@firebase/app";
import "firebase/auth";
import "firebase/database";

Don't use import * as firebase from "firebase"; or import firebase from "firebase";

See this GitHub issue for more details.
