This is my first time writing a flutter app.

I write a widget which listening to tap event.

Listener(
  onPointerUp: (e) {
    // A function here
  },
  child: child,
);

But it always has a delay after i tap the widget.

I don’t want a delay on button. I have tried InkWell, GestureDetector and Listener. All of these doesn’t work as i expected.

I searched the problem on google, found that there would have delay on button when it have both onTap and onDoubleTap event. But i never write onDoubleTap event.

My code is in https://github.com/yuanzui-cf/grassh/blob/main/lib/src/component/window_button.dart . I want to know why it has a delay and how to resolve it.
