How to navigate to screen and remove all rout history [sign out functionality]

Question

How can i navigate to a screen and remove all previous routing history so that the user cannot press back and get to the previous screen?
In my case I want to push the login screen when a user is logged out, but the navigation history is still there so the user can just press back and return to the previous page.

What I have:
A -> B -> C       //Before signing out
A -> B -> C -> L  //After signing out

What I want:
A -> B -> C       //Before signing out
L                 //After signing out

Solution 1

Use below code

Navigator.pushAndRemoveUntil(context, MaterialPageRoute(builder: (context) => HomePage(),), (route) => false);

Change HomePage() to your class name "L".

pushAndRemoveUntil will remove all existing routes and push to new page.

Solution 2

Navigator.of(context).popUntil(ModalRoute.withName('L'));

I've seen this suggestion before, but when I execute the code I land on the page after the login: A -> B -> C becomes L -> A. If I press back I will return to the login page.

Make sure you are using pop on backpress. Because im using this on every sigout code

I'm not using named routes. Is there an equivalent version for routing worth screen arguments?

[Joel Broström]

Yes, it also has 290+ upvotes in the other PR, so it should work. What do you mean with pop on backpress. Isn't that handled by the flutter navigation framework?

The code you provided works, it's my firebase connection that had little bit of lag so when i signed out and checked my auth status it stil said authenticated and proceeded to login. Thanks for your help buddy!
