I am using react-native-paper along with react-navigation and the notification tray background color is not a darker shade of the AppBar color as shown in the documentations of react-native-paper and I cannot figure a way out to do that.

Expected Output:

Current Output

As it can be seen above the notification tray color is the same as the AppBar color. How do I get it to work like the expected output. You can see the current implementation on the link above.
