How to reload the layout

Hi,

Not sure if this has been handled or not, but I couldn't find a way to reload the base view/stack view. Is the support added, if yes, could you please help me with that?

Also, I need a way to modify a height of a view based on some condition. For eg., in landscape I need the view to take 100 px height and in portrait it should take 150 px. Is there any way we can achieve that?
