Button problem

[aDarkRider]

I'm trying to use the latest version in my app. I'm trying to create a simple button in the dark theme of my application but the shadows around the button are still white. How can I create a dark theme Neumorph Button. I have tried applying the style. Below is my code:
<soup.neumorphism.NeumorphButton
android:id="@+id/get_started"
android:layout_width="wrap_content"
style="@style/Widget.Neumorph.Button"
android:layout_height="wrap_content"
android:fontFamily="@font/poppins_regular"
android:text="Get Started"
android:textColor="@color/white"
app:neumorph_shapeType="flat"
app:layout_constraintBottom_toBottomOf="parent"
app:layout_constraintEnd_toEndOf="parent"
app:layout_constraintStart_toStartOf="parent" />
