Spacer: to add some whitespace between controls

[ndonkoHenri]

I want it to be a discussion, before raising an issue.
So, I think this Spacer(https://api.flutter.dev/flutter/widgets/Spacer-class.html) is super useful. And should be implemented.
What do you guys think?

So, I had an answer for a way round on discord.
Adding a Container in the UI, and if needed, modify its height and width.
