Header
Stay organized with collections
Save and categorize content based on your preferences.
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
