In Flutter, navigation refers to the process of moving between different screens or pages in your app. The Navigator class is responsible for managing the navigation stack, which keeps track of the route history. You can use the push and pop methods of the Navigator class to navigate forward and backward, respectively, in the navigation stack.
Pushing a New Screen:
The push method is used to navigate to a new screen. You provide it with a Route object, typically created using the MaterialPageRoute constructor, which defines the destination
Popping the Current Screen:
To navigate back to the previous screen, you can use the pop method. This removes the topmost route from the navigation stack.
