The Tooltip docs say:

Wrap the button in a Tooltip widget to show a label when the widget long pressed (or when the user takes some other appropriate action).

The (or when the user takes some other appropriate action) implies we could choose other actions to show the Tooltip, or that at least they are already built-in, but the docs don't mention any other ways to show the Tooltip neither how to reconfigure it's default behavior, like changing "long-press" to "on tap".

The only hint I could get to the explanation of this sentence is in the waitDuration description where it says the Tooltip will also be shown on a pointer hover.

So are the docs incomplete or the Tooltip should have additional functionality?
