Flutter navigation, reopen page instead of pushing it again

Question

I'm new to flutter and I'm working on an App that have multiple screens.

I would like to know to stop flutter from creating multiple screens of the same route, for example I have Page 1 and Page 2, if I click on the button to navigate to Page 2 and clicked again on the same button the application will push a new screen of Page 2 and i will have it twice and if I click on the return button it will send me back to the first created Page 2

is there a way to create every page only once and then reopen it if it's already pushed to the stack ?

I'm using Navigator.push for all my navigation

These answers are not correct. PushReplacement will still create a new instance of the widget. That's very simple to identify if you have a scrollable list in RouteA and scroll it before navigating to a RouteB. When you pushReplacement(RouteA) , you'll see the scrolling position have changed to its initial state. That is because a new widget was instantiated, and that is not the behaviour you want.

You should use popUntil, as previously answered by JoaoSoares
