How to draw an arc from points in Flutter

Question

I'm trying to draw an arc with drawPoints method, how can I calculate the points necessary to make an arc? (of any radius)

  @override
  void paint(Canvas canvas, Size size) {
    final pointMode = ui.PointMode.points;
    final points = [
      Offset(50, 100),
      Offset(150, 75),
      Offset(250, 250),
      Offset(130, 200),
      Offset(270, 100),
    ];

    final paint = Paint()
      ..color = Colors.black
      ..strokeWidth = 1
      ..strokeCap = StrokeCap.round;
    canvas.drawPoints(pointMode, points, paint);

I've stumbled across this article which helped me a lot drawing arcs (didn't do it with points though), but maybe it helps anyway.
