How To Prevent Navigation Loops In Flutter

Question

In my application I have 13 screens in total, some of them has links to other screens, I also have a drawer that has links to most of these screens.

The following image shows the only navigation flow that I want in the app:

as you can see the only screens that have links to other screens are the home, warehouses and close expiry screens. But because the drawer exists in every screen I now can navigate from warehouses to products then warehouses then products and so on, or from close expiry to warehouses to products to home to close expiry until the end of time.

what I want is this: whenever the user navigates to one of the home screen direct links, the screens stack should only contain the home screen and the navigated to screen with it's descendants.

In other words, I want to make sure the the screens stack has only one instance of any screen in the app. I don't want loops, and I also don't want to get rid of the drawer.

Is there any way to achieve that?

Thanks in advance.

Answer 1

The only way that I've found is to always navigate to the home screen before going to any other screen, this way we can achieve exactly what is asked in the question
