Setup flutter app with firebase for google authentication using getx package
GetX works with stream and observable whereas provider works on the concept of notify and listen
When you run the project, at that time there will be a home screen; it will check whether the user is authenticated or not; if the user is authenticated, then the user will move to the welcome screen where the user's profile is displayed; if the user is not authenticated, then from the home screen, the user will move to the login screen- where the user will make a login and after that the user will move to the welcome screen.
