Impossible to add Controls (eg FAB) layered above tabbar


Hi there, I’ve an issue due I can’t find any working solution. I am trying to add FAB Buttons with fablist in the upper area of my app, ideally into the navbar. Unfortunately, the tabbar will always apper over the FAB, so that you cannot see all of the buttons. It seems to be impossible to change the z-index of the tabbar to get things work… Any idea will be appreciated.
