Length constructor

Length({ int significantFigures = 10, bool removeTrailingZeros = true, dynamic name, })

Class for length conversions, e.g. if you want to convert 1 meter in inches:

var length = Length(removeTrailingZeros: false);
length.convert(Unit(LENGTH.meters, value: 1));
print(length.inches);

Implementation

Length({this.significantFigures = 10, this.removeTrailingZeros = true, name}) {
  size = LENGTH.values.length;
  this.name = name ?? PROPERTY.length;
  for (LENGTH val in LENGTH.values) {
    unitList.add(Unit(val, symbol: mapSymbols[val]));
  }
