Update the code to work with new FlutterFire
I would like to upgrade all the dependencies of this project. As new FlutterFire has came so I would like to update all the firebase functions which have been deprecated or are not working.
I will not change your implementation but will update the code to work with new FlutterFire as when we add firebase_messaging it will not work as we need to add firebase_core and ultimately upgrade all libraries .
I have seen people facing problem in upgrading the project.
