AppBar(
   scrolledUnderElevation: 0.0,
   backgroundColor: Colors.transparent,
)

or

forceMaterialTransparency: true,

These worked for me.

Note: both will make the appbar jerky for page transitions. And i have not found the perfect solution yet.

Try to put:

shadowColor: Theme.of(context).colorScheme.surface,
backgroundColor: Theme.of(context).colorScheme.surface,

or whatever color you want. This should disable color change when scrolling

Try to set scrolledUnderElevation to 0 in the AppBar.

scrolledUnderElevation: defines The elevation that will be used if this app bar has something scrolled underneath it.

That's if your TabBar is placed in the bottom of the AppBar. if not then try to provide some code.
