paintWithPattern method

void paintWithPattern(Canvas canvas, double x, double y, double width, double height,)

After clipping the canvas to the shape we want, paint the Pattern on the rectangle defined by the provided x, y, width, height.

Implementation

void paintWithPattern(
    Canvas canvas, double x, double y, double width, double height) {
  final stripesCount = featuresCount * 2;
  var stripeH = height / stripesCount / 1.5;
  final paint = Paint()
    ..style = PaintingStyle.fill
    ..color = bgColor;
  canvas.drawRect(Rect.fromLTWH(x, y, width, height), paint);
  var dy = 0.0;
  final rectsPath = Path();
  for (var i = 1; i < stripesCount; i += 2) {
    // Start the pattern from half a background stripe height.
    final rect = Rect.fromLTWH(x, y + dy + stripeH, width, stripeH);
    rectsPath.addRect(rect);
    dy += stripeH * 3;
  }
  paint
    ..style = PaintingStyle.fill
    ..color = fgColor;
  canvas.drawPath(rectsPath, paint);
}
