Hide tooltips after a duration ?

Hi,
Thanks for this amazing repo, the only question is how can hide the tooltip after a duration?

This is a good question! I haven't thought before.

Here is my idea to achieve that:

The tooltip is controlled by selection, showing triggered by on signals and hiding triggered by clear signals (doubleTap by default).

There is a way to emit and detect signals manually: the signalChannel of the element. it is a Dart StreamController. By this method, you can do some magic, like when tooltip is triggered by tapping, record and start a timer, and emit a doubleTap signal back to the chart after a duration.

Please try this way.
