isTap() method not working properly?

It seems to be triggered only when a long press is made over a Parent. Additionally, it is triggered twice in that case (at least for me).

[ReinBentdal]

will look into it in the next couple days. Could you please provide your code where the error occurs?

[JoseDelPino]

Here you have it, thanks for the quick response :)

Not entirely sure what the problem is but i think the problem is just an illusion when testing on a emulator. What feels like a long press on a emulator can be a normal tap on a real device. I would also suggest changing the itTap function to:

..isTap((isTapped) {
  print("The item was tapped $isTapped");
  _goToSection(widget.navigator);
  setState(() => pressed = isTapped);
}

When the setState function is called the widget will rerender. Therefore everthing you want to do should be done before you call setState.

Let me know if this helped. I would also suggest testing it on a real device if you havent yet to see if there is a problem in a "real" scenario.

[JoseDelPino]

The problem still persists, even on a real device. _goToSection(widget.navigator); is executed TWICE only when a long press is release.

Thanks in advance.
