NavHost

• NavHost → is a container which is responsible for rendering (or) displaying a composable screen (or) group of composable screens.

NavController

• NavController → is used to navigate from one screen to another screen

NavGraph

• NavGraph → is like a Map, it will consists of the path connection of the screens.

• The NavController and NavGraph will present inside the “NavHost”.

For Navigating from one screen to another screen, one important concept we need to understand is “Route”

Route

• Route → is similar to a “url” name for different web pages present in a web site.
• Same like that, each screen in an application has it’s unique “url” as a “route”
• We will use this url(route) on the “NavGraph” to point the url to a particular screen.
