title: Theme.MaterialComponents.DayNight not found
body: <p>In my build.gradle, I included the material design library(version 1.1.0) but in <code>styles.xml</code>, when I try to use <code>Theme.MaterialComponents.DayNight</code>, it says <code>cannot resolve symbol</code>. Wasn't the DayNight theme already implemented in material design library 1.1.0? Please help. Thanks.</p>
