stackLine function

List<List<int>> stackLine(List<int> p1, List<int> p2)

Implementation

List<List<int>> stackLine(List<int> p1, List<int> p2) {
  final stack = <List<int>>[];
  final dx = p2[0] - p1[0];
  final dy = p2[1] - p1[1];
  final length = math.sqrt(dx * dx + dy * dy).toInt();
  final rad = math.atan2(dy, dx);
  for (var l = 0; l < length; l++) {
    final x = p1[0] + l * math.cos(rad);
    final y = p1[1] + l * math.sin(rad);
    stack.add([x.toInt(), y.toInt()]);
  }
  return stack.toSet().toList();
}
