VolumeRateFormat class

Allows a VolumeRate to be formatted.

See UnitOfMeasurementFormat for general notes on the pattern syntax and VolumeRate for volume-specific notes.

final volumeRate = 42.liters().per(const Duration(minutes: 1));

// '2520L/hr'
final result1 = VolumeRateFormat().format(volumeRate);

// '2520 Liters per hour'
final result2 = VolumeRateFormat(pattern: "0.## U 'per' R").format(volumeRate);

// '14,950.84 ft³/wk'
final result3 = VolumeRateFormat(
  pattern: "###,##0.## u:ft³'/'r:wk",
  permissibleValueUnits: VolumeUnits.imperial,
  permissibleRateUnits: RateUnits.all,
).format(volumeRate);
