copyWith method

Sp3dMaterial copyWith({ Color? bg, bool? isFill, double? strokeWidth, Color? strokeColor, int? imageIndex, List<Offset>? textureCoordinates, String? name, Map<String, dynamic>? option, })

Creates a copy with only the specified values rewritten.

• bg : Background color
• isFill : If true, fill by bg color.
• strokeWidth : Stroke width.
• strokeColor : Stroke color.
• imageIndex : Invalid if null. When fill is enabled and there are 4 vertex, fill with image with the clockwise order as the vertices from the upper left.
• textureCoordinates : You can specify the part of the image that you want to cut out and use. Use by specifying the coordinate information for the image. Specify the coordinates counterclockwise with a triangle(3 vertices) or rectangle(There are two triangles. 6 vertices).
• name : The material name.
• option : Optional attributes that may be added for each app.

Implementation

Sp3dMaterial copyWith(
    {Color? bg,
    bool? isFill,
    double? strokeWidth,
    Color? strokeColor,
    int? imageIndex,
    List<Offset>? textureCoordinates,
    String? name,
    Map<String, dynamic>? option}) {
  List<Offset>? tCoord;
  if (textureCoordinates == null) {
    if (this.textureCoordinates != null) {
      tCoord = [];
      for (Offset o in this.textureCoordinates!) {
        tCoord.add(Offset(o.dx, o.dy));
      }
    }
  }
  return Sp3dMaterial(
      bg ??
          Color.fromARGB(
              this.bg.alpha, this.bg.red, this.bg.green, this.bg.blue),
      isFill ?? this.isFill,
      strokeWidth ?? this.strokeWidth,
      strokeColor ??
          Color.fromARGB(this.strokeColor.alpha, this.strokeColor.red,
              this.strokeColor.green, this.strokeColor.blue),
      imageIndex: imageIndex ?? this.imageIndex,
      textureCoordinates: textureCoordinates ?? tCoord,
      name: name ?? this.name,
      option: option ?? (option != null ? {...option} : null));
