How to hide bottom tab navigator (persistent_bottom_nav_bar) when the screen is not the main screens-CodePudding

I am currently using persistent_bottom_nav_bar: ^4.0.2 package of flutter which showing 3 screens (A,B,C screens) in the bottom tab navigator. In the first screen I have a button that navigate user to another screen (D screen). The problem is the bottom tab navigator (persistent_bottom_nav_bar) is still showing in D screen, while the main screens are AB,C. Is there a way to hide persistent_bottom_nav_bar when the screen is not one of three main screen ?

CodePudding user response：

You use persistent_bottom_nav_bar which is worthless if you don't want bottom bar in all your screens. You can use simple bottomNavigationBar of Scaffold property. It will work.

CodePudding user response：

can you check persistent_bottom_nav_bar in example code.

onScreenHideButtonPressed: () {
          setState(() {
            _hideNavBar = !_hideNavBar;
          });
        },
