BottomNavigationView's titles' color being a gradient

问题

I need to make the titles in BottomNavigationView in android be of a gradient color.

<?xml version="1.0" encoding="utf-8"?>
<gradient xmlns:android="http://schemas.android.com/apk/res/android"
        android:startColor="@color/gradientLeft"
        android:endColor="@color/gradientRight"
        android:angle="0"/>

I have the colors set up and it works with e.g. icons on BtmNavView, but I can't get the titles to change their color to a gradient.

<com.google.android.material.bottomnavigation.BottomNavigationView
        android:id="@+id/btmNav"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:layout_alignParentBottom="true"
        android:layout_gravity="bottom"
        android:background="?attr/toolbarColor"
        android:theme="@style/Widget.BottomNavigationView"
        app:itemHorizontalTranslationEnabled="false"
        app:itemTextColor="@drawable/test_gradient_colorstatelist"
        app:layout_behavior="com.x.x.tools.BottomNavigationBehavior"
        app:menu="@menu/bottom_nav" />

I have a selector set up too, but to no effect with the titles.

<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item android:state_pressed="true"
    android:color="@color/gradient" />
<item android:state_checked="true"
    android:color="@color/gradient" />
<item android:color="@color/gradient" />

Any ideas how can I change the color of the bottom titles to a gradient?
