Taller row?

Is there a way to increase a row’s height beyond that of its children, so that I can set cross_align=“center” to vertically center it? The only other way I know to do this is to wrap the row in a Padding widget and apply enough padding on the top so that its centered, but I’d like to avoid hard-coding that padding value and instead simply let it use whatever height is available and center vertically based on that. Any way to do something like that?
