Sticky footer: unsure how flex-grow pushes the footer to the base - why?

In the video I watched, Guil shows us how to make a sticky footer with flexbox. Everything makes sense and was explained simply, but I am not completely understanding why using flex-grow would be successful in pushing the footer to the base of the viewport. This is the snippet of code that I am questioning. I understand that it is good syntax, but just not sure why it eliminates the gap forcing footer to the base.

.row {
     flex: 1;

flex-gow stretches the height of .row to the maximum of available space. Guil explains it on minute 2:30.

without flex-grow, the height of .row is defined by its content. with flex-grow, its takes all the available space thats left inside the viewport.

this is my favorite guide for flexbox when i need to recheck something: https://css-tricks.com/snippets/css/a-guide-to-flexbox/

hope it helps you!
