The Navigator widget in Flutter manages a stack of Route objects, where each Route represents a full-screen widget. The push method is used to add a new route to the top of the stack, while the pop method is used to remove the topmost route.

The push method takes two required arguments: the context and the new route. The context is used to find the Navigator widget, and the route is the new screen that you want to navigate to.

On the other hand, the popUntil method allows you to remove all routes above a specified route from the stack. It takes two required arguments: the context and a predicate that determines which route to stop at. The predicate is a function that takes a Route and returns a bool.

For example, you can use the ModalRoute.withName function as the predicate to pop until a route with a specific name. This can be useful when you have a deep navigation stack and you want to return to a specific point without having to pop multiple times.
