straightPath method
Returns a closed Path with coordinates connected with straight line segments.
Implementation
Path straightPath() {
Path path = Path();
// create path starting from point 0, ...
path.moveTo(coords[0].x, coords[0].y);
for (int i = 1; i < coords.length; i++) {
path.lineTo(coords[i].x, coords[i].y);
}
// close path at starting point
path.lineTo(coords[0].x, coords[0].y);
return path;
}
