How to change the android bottom tabbar height in Xamarin.Forms

I spent hours searching a way to increase the bottom tabbar height in android in my Xamarin.Forms project. I did not find any Custom Renderer for that instead I found this

<android.support.design.widget.TabLayout 
    ...
    android:minHeight="300dp"
    />

but it also didn't work for me. Can someone has a solution for this please.
