Overview
App bar is composed of the following components:
It is essentially a FlexibleHeader with a HeaderStackView and NavigationBar added as subviews.
MDCAppBarViewController is the primary API for the component. All integration strategies will
make use of it in some manner. Unlike UIKit, which shares a single UINavigationBar instance across
many view controllers in a stack, app bar relies on each view controller creating and managing its
own MDCAppBarViewController instance.

Behavioral flags
A behavioral flag is a temporary API that is introduced to allow client teams to migrate from an old behavior to a new one in a graceful fashion. Behavioral flags all go through the following life cycle:
- The flag is introduced. The default is chosen such that clients must opt in to the new behavior.
- After some time, the default changes to the new behavior and the flag is marked as deprecated.
- After some time, the flag is removed.
- Recommended behavioral flags
- Removing safe area insets from the min/max heights
- Enabling top layout guide adjustment
- Enabling inferred top safe area insets
See the FlexibleHeader documentation for additional usage guides.
