I tried to look for a way of customising my bottom navigation bar as seen in the image.
I still cannot get the exact look. I am able to highlight the Icon with the blue box around it when its selected but not with label. is there a way to achieve this or to approach differently ? glad if someone can help with a code snippet.

Here's my simple solution without any third party package, You can customize this widget, I am sure there's a lot of scope for improvement. Hope this gives you an idea on How to move further.
