toPath method

Path toPath({ required double progress, int startAngle = 0, bool repeatPath = false, bool closePath = true, double rotationPivotX = 0, double rotationPivotY = 0, Path? path, })

Returns a Path for a Morph.

progress is the Morph's progress.

path is a Path to reset and set with the new path data.

startAngle is an angle (in degrees) to rotate the Path to start drawing from. If startAngle is non zero, then caller has to use the returned Path, as path transformation creates a new path.

repeatPath is whether or not to repeat the Path twice before closing it. This flag is useful when the caller would like to draw parts of the path while offsetting the start and stop positions (for example, when phasing and rotating a path to simulate a motion as a Star circular progress indicator advances).

closePath is whether or not to close the created Path.

rotationPivotX is the rotation pivot on the X axis. By default it's set to 0, and that should align with Morph instances that were created for RoundedPolygon with zero centerX. In case the RoundedPolygon were normalized (i. e. moved to (0.5, 0.5)), or where created with a different centerX coordinated, this pivot point may need to be aligned to support a proper rotation.

rotationPivotY is the rotation pivot on the Y axis. By default it's set to 0, and that should align with Morph instances that were created for RoundedPolygon with zero centerY. In case the RoundedPolygon were normalized (i. e. moves to (0.5, 0.5)), or where created with a different centerY coordinated, this pivot point may need to be aligned to support a proper rotation.

Implementation

Path toPath({
  required double progress,
  int startAngle = 0,
  bool repeatPath = false,
  bool closePath = true,
  double rotationPivotX = 0,
  double rotationPivotY = 0,
  Path? path,
}) {
  return pathFromCubics(
    path: path ?? Path(),
    startAngle: startAngle,
    repeatPath: repeatPath,
    closePath: closePath,
    cubics: asCubics(progress),
    rotationPivotX: rotationPivotX,
    rotationPivotY: rotationPivotY,
  );
}
