title: Increase height of selected icon in navigation bottom view android when using custom icon?
body: <p>Please, I want to use custom icon for bottom navigation view in android like this. How to change icon position when selected? When they are selected they go up a bit. Do you create a selected icon with a certain margin or is there a way to set the height in android? This image is from a flutter library though. I want to reproduce that in an Android Java project. Or find a library that implement it
