After the Flutter upgrade to Flutter Version 3.17, many controls have a new look. I managed to make most of the adjustments to get the old design back. But I have a ListView in a Tab of a TabBar. The elements are now displayed a little differently. But I can't figure out where and how I have to make the necessary settings on the theme to get the old status back. I'm missing the "shadow" between Tabbar and ListView. I once took a greatly enlarged picture. Look for the new one on the left. On the right the old condition. Can someone maybe give me a tip? Or is there a documentation on how to adapt the old Flutter ThemeData to the new ThemeData?
