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

The AppBar widget has a property called automaticallyImplyLeading. By default it's value is true. If you don't want flutter automatically build the back button for you then just make the property false.

appBar: AppBar(
  title: Text("YOUR_APPBAR_TITLE"), 
  automaticallyImplyLeading: false,
),

To add your custom back button

appBar: AppBar(
  title: Text("YOUR_APPBAR_TITLE"), 
  automaticallyImplyLeading: false,
  leading: YOUR_CUSTOM_WIDGET(),
),

If navigating to another page                                                Navigator pushReplacement   can be used  It can be used If you re navigating from login to home screen         Or you can use    AppBar automaticallyImplyLeading  false

You can remove the back button by passing an empty new Container   as the leading argument to your AppBar  If you find yourself doing this  you probably don t want the user to be able to press the device s back button to get back to the earlier route  Instead of calling pushNamed  try calling Navigator pushReplacementNamed to cause the earlier route to disappear  The function pushReplacementNamed will remove the previous route in the  backstack and replace it with the new route  Full code sample for the latter is below  import  package flutter material dart    class LogoutPage extends StatelessWidget      override   Widget build BuildContext context        return new Scaffold        appBar  new AppBar          title  new Text  quot Logout Page quot                   body  new Center          child  new Text  You have been logged out                           class MyHomePage extends StatelessWidget       override   Widget build BuildContext context        return new Scaffold        appBar  new AppBar          title  new Text  quot Remove Back Button quot                   floatingActionButton  new FloatingActionButton          child  new Icon Icons fullscreen exit           onPressed                 Navigator pushReplacementNamed context   quot  logout quot                                      void main       runApp new MyApp        class MyApp extends StatelessWidget      override   Widget build BuildContext context        return new MaterialApp        title   Flutter Demo         home  new MyHomePage          routes             quot  logout quot         gt  new LogoutPage

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 lt dynamic gt   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           gt  false     Cheers
