I'm using the NavigationBar class for the navigation through my app, but I have a problem, which is that I can't preserve the information on the screen when I'm navigating, so everything loads up again at the start of the screen. How should I do to preserve the screen even if I am in another screen so everything doesnt load up again?

You can use bloc for your state management.

Use states. There are a lot of options available like for example stateful widgets.
