Conditionally activate Material UI tooltip?
Should be
<Tooltip title={warningText == null ? "" : warningText}> <Button>Do action</Button> </Tooltip>the docs say that it won't be displayed if the string length is zero.

Tooltip title. Zero-length titles string are never displayed.
You should take a look at https://material-ui.com/api/tooltip/
There are options like
- disableFocusListener
- disableHoverListener
- disableTouchListener
- interactive
I think interactive={true} should fit your needs best
<Tooltip title={warningText} interactive={!warningText}>...</Tooltip>
