build method

@override Widget build(BuildContext context)

Override this method to build widgets that depend on the state of the listenable (e.g., the current value of the animation).

Implementation

@override
Widget build(BuildContext context) {
  return GestureDetector(
    onTap: () {
      if (onTap != null) {
        onTap!();
      }
    },
    child: SizedBox(
      child: CustomPaint(
        painter: customPainter,
      ),
    ),
  );
}
