## 1. Which method should be used to navigate to a new screen with Navigator 1.0?

**Answer**

Navigator.push() adds a new route to the navigation stack, allowing navigation to a new screen while keeping the previous screen in the stack. This method takes context and a Route (usually MaterialPageRoute) as parameters. Push stacks the new route, while pop removes it from the stack.

## 2. What does Navigator.pop() return when sending data back to the previous screen?

**Answer**

Navigator.pop() can take an optional argument that will be returned to the previous screen via the Future returned by Navigator.push(). This allows sending a result (confirmation, selection, modified data) back to the screen that initiated navigation. Use await with push() to retrieve this result.

## 3. What is the role of MaterialPageRoute in Flutter navigation?

**Answer**

MaterialPageRoute is a route that uses Material Design transitions (slide from right on iOS, fade on Android). It takes a builder that returns the destination widget. It automatically handles transition animations and respects platform conventions for a native user experience.
