I was trying to create a layout the way it looks like now. But here's a problem.

When using a flyout, I want to use a flyout that covers the screen. However, there was a problem that only the page was overwritten as shown in the picture.

I want to add various buttons after putting a view or navigation view at the top, making a button with a toolbar, and moving the flyout button at the bottom.
Anyone who knows can tell me!?
