onLinearGradient(double fromX, double fromY, double toX, double toY, Int32List colors, Float32List? offsets, int tileMode, int id) → void
A linear gradient shader has been parsed.
onMask() → void
Prepare to draw a new mask, until the next onRestoreLayer command.
onPaintObject({required int color, required int? strokeCap, required int? strokeJoin, required int blendMode, required double? strokeMiterLimit, required double? strokeWidth, required int paintStyle, required int id, required int? shaderId}) → void
