Hi Darvin, this was a side-project.

In real world, all the apps where I am involved in are using Bootstrap. However, we never referenced any existing Material UI Bootstrap library as-is. We ended up “materializing” the default Boostrap and customizing it to match our design system, which is using Google’s Material Design key elements, but it is not exact copy in style, branding and some specific UI patterns such as tables or search & filter.
