LengthRateFormat class

Allows a LengthRate to be formatted.

See UnitOfMeasurementFormat for general notes on the pattern syntax and LengthFormat for length-specific notes.

final lengthRate = 42.meters().per(const Duration(seconds: 1));

// '42 m/s'
final result1 = LengthRateFormat().format(lengthRate);

// '42 meters per second'
final result2 = LengthRateFormat(pattern: "0.## U 'per' R").format(lengthRate);

// '8,267.72 ft/min'
final result3 = LengthRateFormat(
  pattern: "###,##0.## u:ft'/'r:min",
  permissibleValueUnits: LengthUnits.imperial,
).format(lengthRate);
