flutter remove back button on appbar

Question

I am wondering, if anyone knows of a way to remove the back button that shows up on the appBar in a flutter app when you use Navigator.pushNamed to go to another page. The reason I do not want it on this resulting page is that it is coming from the navigation and I want users to use the logout button instead, so that the session starts over.

Answer 1

I believe the solutions are the following

You actually either:

• Don't want to display that ugly back button ( :] ), and thus go for : AppBar(...,automaticallyImplyLeading: false,...);

• Don't want the user to go back - replacing current view - and thus go for: Navigator.pushReplacementNamed(## your routename here ##);

• Don't want the user to go back - replacing a certain view back in the stack - and thus use: Navigator.pushNamedAndRemoveUntil(## your routename here ##, f(Route<dynamic>)→bool); where f is a function returning truewhen meeting the last view you want to keep in the stack (right before the new one);

• Don't want the user to go back - EVER - emptying completely the navigator stack with: Navigator.pushNamedAndRemoveUntil(context, ## your routename here ##, (_) => false);
