How to increase min-height of q-layout?

[zaynab-raisi]

I have this for q-layout: view="lhh Lpr lff". Quasar sets min-height based on viewport height. Before fetching data, there is footer in viewport and after that, footer jumps to the end of page. To prevent this, I want to set min-height: viewport-height + footer-height. How can I do that?
