MasterDetailLayout class
Very similar to TwoPageLayout. This layout has better support for having related, "deeper", content in the second page that would usually be accessed by navigating to a new page.
It's common to use this type of layout when you have a list of items that when tapped let you view a detailed view of the item. Email and instant messaging apps are examples of this.
On a single screen device, or when the app is only running on a single
screen, master will display first. When isSelected is true, detail is
displayed as a new page on top of master, similar to using Navigator.push
.
When spanned across 2 screens, both master and detail display at the same time and no navigation occurs. Even when isSelected is false.
MasterDetailLayout
also handles switching between spanned and non-spanned
modes appropriately, so the UI will be the same if you select and then span,
or span and then select.
