```xml <com.google.android.material.navigation.NavigationView android:id="@+id/navigation_view" android:layout_width="wrap_content" android:layout_height="match_parent" android:layout_gravity="start" app:insetForeground="@android:color/transparent" app:menu="@menu/toolbar" />
```
- You must add the insetForeground
```app:insetForeground="@android:color/transparent"```
