Flutter: How to disable onTap for a while in gesture detector?

Question

I have a GestureDetector in a custom stateless view. when onTap triggered I show a snack bar that displays some info. When the user makes multiple clic

Answer 1

Personally I use two others methods from GestureDetector:

onTapDown: When user is pressing your widget.

onTapUp: When user leave the widget.

onTap: Is when tap down and tap up follows. If user slide his finger too much Flutter take this like a cancel tap.

onTapCancel: When user cancel.

bool pressing = false;

GestureDetector(
  // when user is pressing
  onTapDown: (details) {
    setState(() {
      pressing = true;
    });
  },
  // when user leaved
  onTapUp: (details) {
    setState(() {
      pressing = false;
    });
  },
  // when user leaved
  onTapCancel: () {
    setState(() {
      pressing = false;
    });
  }
  // the action to do when user tap
  onTap: () {
    // code...
  }
);
