FoldPreview class
Shows child as it would look on device in posture, on any screen:
the window size, the fold, the hinge status and the safe area are faked,
so FoldInfo, FoldScaffold and FoldTwoPane behave like on the device.
Use it to build foldable layouts without a foldable, in widget tests, in golden tests and for screenshots. With controls you get a small toolbar to switch device, posture and orientation.
