Below are my dependencies

implementation 'com.google.android.material:material:1.0.0'
implementation 'androidx.appcompat:appcompat:1.0.2'
implementation 'androidx.constraintlayout:constraintlayout:1.1.3'

My layout.xml

<?xml version="1.0" encoding="utf-8"?>
<androidx.coordinatorlayout.widget.CoordinatorLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    android:id="@+id/main_content"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:background="#ffffff"
    android:fitsSystemWindows="true">


    <com.google.android.material.bottomappbar.BottomAppBar
        android:id="@+id/bottomBar"
        style="@style/Widget.MaterialComponents.BottomAppBar"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:layout_gravity="bottom"
        android:backgroundTint="@color/colorPrimary"
        app:fabAlignmentMode="center"
        app:fabCradleMargin="10dp"
        app:fabCradleVerticalOffset="4dp"
        app:navigationIcon="@drawable/ic_drawer" >

    </com.google.android.material.bottomappbar.BottomAppBar>

    <com.google.android.material.floatingactionbutton.FloatingActionButton
        android:id="@+id/fab"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        app:layout_anchor="@id/bottomBar"
        app:srcCompat="@drawable/ic_apps" />

</androidx.coordinatorlayout.widget.CoordinatorLayout>

The Above code is working fine for me

But when i update the dependencies of material design 

implementation 'com.google.android.material:material:1.1.0-alpha01'

I'm getting below error:

There is some issue with material:1.1.0-alpha01

A simple solution is to change the parent theme

<style name="AppTheme" parent="Theme.MaterialComponents.Light.DarkActionBar">
        <!-- Customize your theme here. -->
       
</style>
