Exclude widget from scrolling in flutter

I was looking for design inspiration for my website and came across a very interesting design, this one (in web view).

What intrigued me, was how the brand name text (DYNAMIC STUDIOS) kept its static position, while the rest of the "widgets" -both in front and behind the text- were included in the scrolling.

My question is: how could we implement this feature with Flutter?

If we only had items in front or behind the Text, then with a simple Stack and SingleChildScrollView that could have easily been done. But how can you "Stack" an item in between "a scroll view"?
