Which method should be used to navigate to a new screen with Navigator 1.0?
Antwort
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.
2What does Navigator.pop() return when sending data back to the previous screen?
What does Navigator.pop() return when sending data back to the previous screen?
Antwort
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.
