Is there an equivalent od QSpace, but vertical?

[wsw70]

I have a page that consists of

• a container: <q-layout class='q-pa-md full-height flex column'>
• inside this container are three <div>.

I would like the first and third <div> to take the space of its contents (this is done by default), and the second <div> is intended to be empty and take all remaining space (pushing the top and bottom <div> away).

That would be the equivalent of a <q-space>, but for vertical space.

Since I dod not find anything relevant in the documentation for columns, I tried to make it a <div style="flex: 1"></div> but it did not expand as expected.

What is the correct approach?
