TabBarView | Android Library to help you create actionbar tabs | Android library

I'm relatively new to Flutter and am stuck on a Tab Bar issue.

I've created this tab bar on a pop-up container. I'd like the tab bar itself to remain in place, with the content scrolling beneath it. However, in my current version the whole section (incl. tab bar options) gets pushed beneath the text container above.

How can I keep this fixed? I've looked into SliverAppBars, but I don't need a full app bar in place, just the tab bar.

Code below - with a focus on the NestedScrollView section. Any help greatly appreciated!

As the title above, I want the page I've scrolled down to scroll back up when the BottomNavigationBar is pressed (double-pressed). I've managed to make it, no problem. But there is a problem if on the page there is contain a TabBar.

For Example I have a bottom navigation bar, that contains two pages:

HomePage and ProfilePage

On the HomePage I have a TabBar, and that contains two pages also:

FirstTabBarView and SecondTabBarView

The problem is when I've scrolled those two pages down (HomePage & ProfilePage at a different) I just want the FirstTabBarView view page to scroll to the top if I'm currently opening the FirstTabBarView page. But from my code, if I press the BottomNavigationBar button twice, both FirstTabBarView and SecondTabBarView both scroll up.

This is just a simple code sample, you can copy-paste and test it on the dart pad directly
