Our Ti.UI.Toolbar is currently using the Java androidx.appcompat.widget.Toolbar class. It should be updated to use the newer MaterialToolbar class. The newer class supports the material theme.
We must replace our usage below...
The app must use a "Theme.MaterialComponents" based theme or else an exception will occur. So, app's using a custom theme based from "Theme.AppCompat" or similar will crash. This is normal and the exception will state that the theme will need to change.
