Headers help drivers understand which app and what part of the app they're
using. They need to be brief and easy to read at a glance while on the road.
Headers must include at least one of the following: text, app icon, or back
button.
Headers can include:
Icon or image (optional), such as app icon
Text (limited to one line – longer text is truncated), typically the
title of the screen
This example shows different types of headers you can create.

Template support
You can use a header in all templates except the Navigation template. In

the optional action strip.
