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) {
  Animation? animation = listenable as Animation?;
  return new CustomPaint(
    foregroundPainter: Circle(
      xCoordinate: xCoor,
      yCoordinate: yCoor,
      color: pointColor,
      pointSize: pointSize,
      blinkRadius: animation!.value,
    ),
  );
}
