layout method

Implementation

@override
PwBox layout(Context context, BoxConstraints constraints) {
  final (String bg, String fg) = _palette(tone);
  // Intrinsic chip — avoid Container expand-to-maxWidth when parent is tight.
  final PwBox chip = Padding(
    padding: padding,
    child: DecoratedBox(
      decoration: BoxDecoration(color: backgroundColor ?? bg),
      child: Text(
        label,
        softWrap: false,
        style: TextStyle(
          fontSize: fontSize,
          fontWeight: FontWeight.bold,
          color: foregroundColor ?? fg,
        ),
      ),
    ),
  ).layout(context, const BoxConstraints());
  return ProxyBox(constraints.constrain(chip.size), child: chip);
