Change the color of overflow menu icons in a material toolbar

Question

I want to change the overflow menu icons color in my material toolbar depending on the android:theme value.

In this example my search icon is affected by the toolbar's theme via some magic related to the app:actionViewClass attribute implementation, but my info icon is not.

My toolbar:

<?xml version="1.0" encoding="utf-8"?>
<com.google.android.material.appbar.AppBarLayout
    xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:fitsSystemWindows="true"
    app:liftOnScroll="true">

    <com.google.android.material.appbar.MaterialToolbar
        android:id="@+id/toolbar"
        android:layout_width="match_parent"
        android:layout_height="?attr/actionBarSize"
        android:theme="@style/ThemeOverlay.MaterialComponents.Dark.ActionBar"
        style="@style/Widget.MaterialComponents.Toolbar.Primary"
        app:title="@string/app_name"
        app:menu="@menu/menu_main"
        app:layout_scrollFlags="scroll|enterAlways|snap"/>

</com.google.android.material.appbar.AppBarLayout>

My menu:

<?xml version="1.0" encoding="utf-8"?>
<menu
    xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto">

    <item
        android:id="@+id/action_search"
        android:icon="@drawable/ic_search_24dp"
        app:showAsAction="always"
        app:actionViewClass="androidx.appcompat.widget.SearchView"
        android:title="TODO" />

    <item android:id="@+id/action_info"
        android:icon="@drawable/ic_info_24dp"
        app:showAsAction="always"
        android:title="TODO" />

</menu>

Does a simple solution exists?

You can use:

<com.google.android.material.appbar.MaterialToolbar
    style="@style/Widget.MaterialComponents.Toolbar.Primary"
    android:theme="@style/MyThemeOverlay_Toolbar"
    ...>

  <style name="MyThemeOverlay_Toolbar" parent="ThemeOverlay.MaterialComponents.Toolbar.Primary">
    <!-- color used by navigation icon and overflow icon -->
    <item name="colorOnPrimary">@color/myColor</item>
  </style>
