cast method

@override int cast(dynamic value)

Casts the argument to this data type, otherwise throw an ArgumentError.

Implementation

@override
int cast(dynamic value) {
  if (value is num) {
    if (isSigned) {
      return value.toInt().toSigned(bits);
    } else {
      return value.toInt().toUnsigned(bits);
    }
  } else if (value is BigInt) {
    if (isSigned) {
      return value.toSigned(bits).toInt();
    } else {
      return value.toUnsigned(bits).toInt();
    }
  } else if (value is Fraction) {
    return cast(value.toInt());
  } else if (value is String) {
    return int.tryParse(value) ?? super.cast(value);
  }
  return super.cast(value);
