formatPrice function

String formatPrice(Decimal? val, { int? precision, bool showSign = false, bool signFirst = false, RoundMode roundMode = RoundMode.truncate, bool cutInvalidZero = true, bool enableGrouping = true, ShrinkZeroMode? shrinkZeroMode, ShrinkZeroConverter? shrinkZeroConverter, ExplicitDirection? direction, String prefix = '', String suffix = '', String? defIfZero, String defIfNull = '--', })

Format price value 格式化价格值

This is a convenience function that wraps formatNumber with price-specific defaults:

• Trailing zeros removed by default (cutInvalidZero = true)
• Grouping enabled by default (enableGrouping = true)
• Truncate rounding mode by default (roundMode = RoundMode.truncate)

这是一个便捷函数，使用价格特定的默认值包装 formatNumber：

• 默认删除尾部零 (cutInvalidZero = true)
• 默认启用分组 (enableGrouping = true)
• 默认截断舍入模式 (roundMode = RoundMode.truncate)

Implementation

String formatPrice(
  Decimal? val, {
  int? precision,
  bool showSign = false,
  bool signFirst = false,
  RoundMode roundMode = RoundMode.truncate,
  bool cutInvalidZero = true,
  bool enableGrouping = true,
  ShrinkZeroMode? shrinkZeroMode,
  ShrinkZeroConverter? shrinkZeroConverter,
  ExplicitDirection? direction,
  String prefix = '',
  String suffix = '',
  String? defIfZero,
  String defIfNull = '--',
}) {
  return formatNumber(
    val,
    precision: precision,
    showSign: showSign,
    signFirst: signFirst,
    roundMode: roundMode,
    cutInvalidZero: cutInvalidZero,
    enableGrouping: enableGrouping,
    shrinkZeroMode: shrinkZeroMode,
    shrinkZeroConverter: shrinkZeroConverter,
    direction: direction,
    prefix: prefix,
    suffix: suffix,
    defIfZero: defIfZero,
    defIfNull: defIfNull,
  );
