  final resolved = resolveFont(canvas.document);

  if (background != null) {
    canvas.setFillColor(background);
    canvas.drawRect(0, 0, size.x, size.y);
    canvas.fillPath();
  }

  if (borderColor != null && borderWidth > 0) {
    canvas.setStrokeColor(borderColor);
    canvas.setLineWidth(borderWidth);
    canvas.drawRect(0, 0, size.x, size.y);
    canvas.strokePath();
  }

  canvas.setFillColor(color);
  // The baseline sits above the bottom edge by the depth of the font
  // descenders, otherwise letters such as "g" would come out clipped.
  canvas.drawString(
    resolved,
    fontSize,
    text,
    padding,
    padding + (-resolved.descent) * fontSize,
  );
