Draw the Triangle shape marker

Implementation

void drawTriangle(Path path, double x, double y, double width, double height) {
  path.moveTo(x - width / 2, y + height / 2);
  path.lineTo(x + width / 2, y + height / 2);
  path.lineTo(x, y - height / 2);
  path.lineTo(x - width / 2, y + height / 2);
  path.close();
