Hi!

I've seen projects which use many screens each one for different layout and functionality.

I've seen projects with only one screen (like wizard workflow) where content is changed on user interaction (and this seems to be logical to use single screen in wizards).

But also I've seen projects (apps like game or messenger or phone settings utility) which use single screen for different functionalities.

I can see such advantages of having single screen in app:

• keep same decoration design and menu or toolbar (which may be also achieved with inheritance)
• keep single screen in ui stack (which may be achieved by pop/push screen)
• easy to handle data over application

Can you tell other advantages/disadvantages of single screen app?
When its better to use this approach?

Thank you!
