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);
