Use case

I'm interested in sending analytics events when a user triggers a tooltip, but it looks like this isn't possible without a somewhat hacky workaround, like:

• Essentially reimplementing Tooltip with the callback functionality
• Using a Stack to overlay a GestureDetector on top of the tooltip widget
• Adding a new GestureDetector as the immediate child of the Tooltip -- this seems like a hacky solution

Proposal

It seems Tooltip should offer an onTriggered void callback that gets invoked when the user activates it.
