Pop all screen when switching back to a tab

[andreferreiravntrs]

This is my current configuration. I would like to have the following flow:

• Render first TabItem initial screen;
• Push and render new screen inside the first TabItem with this script:

onPressed: () => pushNewScreen(
  context,
  screen: MyGroupsScreen(),
),

• Click on second TabItem and render a initial screen
• Return to first TabItem by clicking on the tab and render the initial screen;

What is happening at the moment is that the initial screen is not rendering when returning to a previous TabItem. Am I configuring something wrong? What should i do here?

return PersistentTabView(
      context,
      controller: _controller,
      screens: _buildScreens(),
      items: _navBarsItems(),
      confineInSafeArea: true,
      backgroundColor: Colors.white,
      handleAndroidBackButtonPress: true,
      resizeToAvoidBottomInset: true,
      stateManagement: true,
      hideNavigationBarWhenKeyboardShows: true,
      decoration: NavBarDecoration(
        colorBehindNavBar: Colors.white,
        border: Border(
          top: BorderSide(color: ColorPalette.veryLightBlue, width: 1.0),
        ),
      ),
      padding: NavBarPadding.all(0.0),
      popAllScreensOnTapOfSelectedTab: true,
      popActionScreens: PopActionScreensType.all,
      itemAnimationProperties: ItemAnimationProperties(
        duration: Duration(milliseconds: 200),
        curve: Curves.ease,
      ),
      screenTransitionAnimation: ScreenTransitionAnimation(
        animateTabTransition: true,
        curve: Curves.ease,
        duration: Duration(milliseconds: 200),
      ),
      navBarStyle: NavBarStyle.style3,
    );

I had the same issue as you do.

popAllScreensOnTapOfSelectedTab only pops the screen if an already selected tab is pressed/tapped again. All the screens pushed on that particular tab will pop until the first screen in the stack. popActionScreens does not seem to work for me either, I am also not sure what an ActionScreen is supposed to be...

I found a solution that works for me, adding the following function in the PersistsentTabBarView:

                selectedTabScreenContext: (context) {
                  if (context != null) {
                      WidgetsBinding.instance?.addPostFrameCallback((_) {
                        Navigator.of(context)
                            .popUntil((route) => route.isFirst);
                      });
                  }
                }

If you only want to pop specific tabs to the root you can achieve this by checking for the tabIndex:

                selectedTabScreenContext: (context) {
                  if (context != null) {
                    PersistentTabController _controller =
                        Provider.of<PersistentTabController>(context,
                            listen: false);
                    if (_controller.index == 0)
                      WidgetsBinding.instance?.addPostFrameCallback((_) {
                        Navigator.of(context)
                            .popUntil((route) => route.isFirst);
                      });
                  }
                },
