edge-swipe back disable (on scaffold)

[david...@gmail.com]

Hello, i have a basic flutter app with two classes that extends statefullwidget class, the first is a login form and the second a basic page with a basic drawer. I would like to prevent my app to navigate back to the login page if the user activate the edge-swipe gesture. 

thanks in advance

If you use Material or CupertinoPageRoute, you can prevent a back swipe if you pushed your route as a fullscreenDialog (https://github.com/flutter/flutter/blob/master/packages/flutter/lib/src/cupertino/route.dart#L85). Using a WillPopScope (https://github.com/flutter/flutter/blob/master/packages/flutter/lib/src/widgets/will_pop_scope.dart) also lets you control when a navigation pop is allowed. It also disables a back swipe. 

Though in your specific case, it sounds like you don't need to keep your login page around. You can use pushReplacement on the Navigator (https://github.com/flutter/flutter/blob/master/packages/flutter/lib/src/widgets/navigator.dart#L681) to replace the first page altogether.
